• Designer issue in VS: Events cannot be set on the object passed to the event binding service ...

  - by serhio

  I have a little problem: the Winform control (that contains between others WPF) suddenly stopped to be displayed in Designer. Message: Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located. Call Stack: at System.ComponentModel.Design.EventBindingService.EventPropertyDescriptor.SetValue(Object component, Object value) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAttachEventStatement(IDesignerSerializationManager manager, CodeAttachEventStatement statement) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager manager, CodeStatement statement) Where could be the problem?

• WCF: Using Streaming and Username/Password authentication at the same time

  - by Kay

  Hi, I have a WCF Service with the following requirements: a) The client requests a file from the server which is transferred as a Stream. Files may be 100MB or larger. I need streaming or chucking or whatever to make sure that IIS is not loading the whole package into memory before starting to send it. b) The client will transfer an ID to identify the file to be downloaded. The user should be authenticated by providing username/password. c) While the username/password part of the communication needs to be encrypted, encryption of the downloaded file is optional for our use case. My other services, where I am returning smaller files, I am using the following binding: <ws2007HttpBinding> <binding name="ws2007HttpExtern" maxReceivedMessageSize="65536000"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </ws2007HttpBinding> But, as I said, that is no good for streaming (Message encryption needs the complete message to encrypt and that is not the case when streaming). So, I asked Microsoft support and I got more or less the following proposal: <bindings> <basicHttpBinding> <binding name="basicStreaming" messageEncoding="Mtom" transferMode="StreamedResponse"> <security mode="Transport"> <transport clientCredentialType="Basic" /> </security> </binding> </bindings> <services> <service behaviorConfiguration="MyProject.WCFInterface.DownloadBehavior" name="MyProject.WCFInterface.DownloadFile"> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicStreaming" contract="MyProject.WCFInterface.IDownloadFile" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MyProject.WCFInterface.DownloadBehavior"> <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> When I use this, I get the following error message: Could not find a base address that matches scheme https for the endpoint with binding BasicHttpBinding. Registered base address schemes are [http]. I am using the Web Development Server so far (for production IIS7). I have two questions. a) How would you configure WCF to achieve the goal? b) If the MS proposal is good: What I am doing wrong, the error message does not really help me. Thanks.

• Datagrid using usercontrol

  - by klawusel

  Hello I am fighting with this problem: I have a usercontrol which contains a textbox and a button (the button calls some functions to set the textbox's text), here is the xaml: <UserControl x:Class="UcSelect" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Control1Name" <Grid x:Name="grid1" MaxHeight="25"> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="25"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="25"/> </Grid.RowDefinitions> <TextBox x:Name="txSelect" Text="{Binding UcText, Mode=TwoWay}" /> <Button x:Name="pbSelect" Background="Red" Grid.Column="1" Click="pbSelect_Click">...</Button> </Grid> And here the code behind: Partial Public Class UcSelect Private Shared Sub textChangedCallBack(ByVal [property] As DependencyObject, ByVal args As DependencyPropertyChangedEventArgs) Dim UcSelectBox As UcSelect = DirectCast([property], UcSelect) End Sub Public Property UcText() As String Get Return GetValue(UcTextProperty) End Get Set(ByVal value As String) SetValue(UcTextProperty, value) End Set End Property Public Shared ReadOnly UcTextProperty As DependencyProperty = _ DependencyProperty.Register("UcText", _ GetType(String), GetType(UcSelect), _ New FrameworkPropertyMetadata(String.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, New PropertyChangedCallback(AddressOf textChangedCallBack))) Public Sub New() InitializeComponent() grid1.DataContext = Me End Sub Private Sub pbSelect_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 'just demo UcText = UcText + "!" End Sub End Class The UserControl works fine when used as a single control in this way: <local:UcSelect Grid.Row="1" x:Name="ucSingle1" UcText="{Binding FirstName, Mode=TwoWay}"/> Now I wanted to use the control in a custom datagrid column. As I like to have binding support I choosed to derive from DataGridtextColumn instead of using a DataGridTemplateColumn, here is the derived column class: Public Class DerivedColumn Inherits DataGridTextColumn Protected Overloads Overrides Function GenerateElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oElement = MyBase.GenerateElement(oCell, oDataItem) Return oElement End Function Protected Overloads Overrides Function GenerateEditingElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oUc As New UcSelect Dim oBinding As Binding = CType(Me.Binding, Binding) oUc.SetBinding(UcSelect.UcTextProperty, oBinding) Return oUc End Function End Class The column is used in xaml in the following way: <local:DerivedColumn Header="Usercontrol" Binding="{Binding FirstName, Mode=TwoWay}"></local:DerivedColumn> If I start my program all seems to be fine, but changes I make in the custom column are not reflected in the object (property "FirstName"), the changes are simply rolled back when leaving the cell. I think there must be something wrong with my GenerateEditingElement code, but have no idea ... Any Help would really be appreciated Regards Klaus

• Can't use attached property on combobox inside hierarchical datatemplate WPF

  - by jesse_t_r

  I'm hoping to use an attached property to assign a command to the selection changed event of a combobox that is embedded inside a treeview. I'm attempting to set the attached property inside the hierchical data template for the tree but the command is not set and does not fire when the item in the combobox is changed. I've found that setting the attached property directly on a combobox outside of a datatemplate works fine; here is how I'm trying to set the property in the template: <HierarchicalDataTemplate x:Key="template1" ItemsSource="{Binding Path=ChildColumns}"> <Border Background="{StaticResource TreeItem_Background}" BorderBrush="Blue" BorderThickness="2" CornerRadius="5" Margin="2,5,5,2" HorizontalAlignment="Left" > <Grid> <Grid.ColumnDefinitions > <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <TextBlock MinWidth="80" HorizontalAlignment="Left" Grid.Column="0" Margin="5,2,2,2" Grid.Row ="0" Text="{Binding Path=ColName}"/> <ComboBox Name="cboColType" Grid.Column="1" HorizontalAlignment="Right" ItemsSource="{Binding Source={StaticResource dataFromEnum}}" SelectedItem="{Binding Path=ColumnType}" Margin="2,2,2,2" local:ItemSelectedBehavior.ItemSelected="{Binding Path=LoadConfigCommand}" /> </Grid> </Border> </HierarchicalDataTemplate> I also tried creating a style <Style x:Key="childItemStyle" TargetType="{x:Type FrameworkElement}"> <Setter Property="local:ItemSelectedBehavior.ItemSelected" Value="{Binding Path=LoadConfigCommand}" /> </Style> and setting the itemcontainerstyle to the style in the hierarchical datatemplate..still no luck .. <HierarchicalDataTemplate> ... <ComboBox Name="cboColType" Grid.Column="1" HorizontalAlignment="Right" ItemsSource="{Binding Source={StaticResource dataFromEnum}}" SelectedItem="{Binding Path=ColumnType}" Margin="2,2,2,2" ItemContainerStyle={StaticeResource childItemStyle}" /> ... </HierarchicalDataTemplate> I'm still learning a lot about WPF so I'm assuming there is something particular about the hierchical datatemplate that is not allowing the attache dproperty to be set..I have found similar posts in the forums and tried to implement their solutions as above, but after a day of searching and experimenting wiht no luck I'm hoping some one has an idea about this...

• WCF service with 2 Bindings and 2 Base Addresses

  - by Sean

  I have written a WCF service (I am a newb) that I want to provide 2 endpoints for (net.tcp & basicHttp) The problem comes when I try to configure the endpoints. If I configure them as seperate services, then my service names are the same which causes a problem. I have seen recomended creating shim classes (classA : MyService, and ClassB : MyService) but that seems smelly. <services> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.HttpBehavior"> <endpoint name="ApplicationHttp" address="Application" binding="basicHttpBinding" bindingConfiguration="HttpBinding" contract="MyWcfService.Interfaces.IMyService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8731/MyWcfService/" /> </baseAddresses> </host> </service> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.MyBehavior"> <endpoint name="Application" address="Application" binding="netTcpBinding" bindingConfiguration="SecuredByWindows" contract="EmsHistorianService.Interfaces.IApplicationHistorianService" /> <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:49153/MyWcfService" /> </baseAddresses> </host> </service> </services> I have tried using a single service with the base address integrated into the address, but that gives me errors as well <services> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.HttpBehavior"> <endpoint name="ApplicationHttp" address="http://localhost:8731/MyWcfService/Application" binding="basicHttpBinding" bindingConfiguration="HttpBinding" contract="MyWcfService.Interfaces.IMyService" /> <endpoint address="http://localhost:8731/MyWcfService/mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <endpoint name="Application" address="net.tcp://localhost:49153/MyWcfService/Application" binding="netTcpBinding" bindingConfiguration="SecuredByWindows" contract="EmsHistorianService.Interfaces.IApplicationHistorianService" /> <endpoint address="net.tcp://localhost:49153/MyWcfService/mex" binding="mexTcpBinding" contract="IMetadataExchange" /> </service> </services> Any ideas?

• Passing windows credentials through web application, to WCF

  - by IP

  I've checked other questions, but I can't find a working answer I have a .Net web application which successfully takes on the callers windows credentials (Thread.CurrentPrincipal is my windows user). Within that app, I call to a WCF service, but my windows identity isn't passed up. Regardless of what I put in the binding: NetTcpBinding binding = new NetTcpBinding(); binding.Security.Mode = SecurityMode.Transport; binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;

• Introducing the Earthquake Locator – A Bing Maps Silverlight Application, part 1

  - by Bobby Diaz

  Update: Live demo and source code now available!  The recent wave of earthquakes (no pun intended) being reported in the news got me wondering about the frequency and severity of earthquakes around the world. Since I’ve been doing a lot of Silverlight development lately, I decided to scratch my curiosity with a nice little Bing Maps application that will show the location and relative strength of recent seismic activity. Here is a list of technologies this application will utilize, so be sure to have everything downloaded and installed if you plan on following along. Silverlight 3 WCF RIA Services Bing Maps Silverlight Control * Managed Extensibility Framework (optional) MVVM Light Toolkit (optional) log4net (optional) * If you are new to Bing Maps or have not signed up for a Developer Account, you will need to visit www.bingmapsportal.com to request a Bing Maps key for your application. Getting Started We start out by creating a new Silverlight Application called EarthquakeLocator and specify that we want to automatically create the Web Application Project with RIA Services enabled. I cleaned up the web app by removing the Default.aspx and EarthquakeLocatorTestPage.html. Then I renamed the EarthquakeLocatorTestPage.aspx to Default.aspx and set it as my start page. I also set the development server to use a specific port, as shown below. RIA Services Next, I created a Services folder in the EarthquakeLocator.Web project and added a new Domain Service Class called EarthquakeService.cs. This is the RIA Services Domain Service that will provide earthquake data for our client application. I am not using LINQ to SQL or Entity Framework, so I will use the <empty domain service class> option. We will be pulling data from an external Atom feed, but this example could just as easily pull data from a database or another web service. This is an important distinction to point out because each scenario I just mentioned could potentially use a different Domain Service base class (i.e. LinqToSqlDomainService<TDataContext>). Now we can start adding Query methods to our EarthquakeService that pull data from the USGS web site. Here is the complete code for our service class: using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.ServiceModel.Syndication; using System.Web.DomainServices; using System.Web.Ria; using System.Xml; using log4net; using EarthquakeLocator.Web.Model;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// Provides earthquake data to client applications.     /// </summary>     [EnableClientAccess()]     public class EarthquakeService : DomainService     {         private static readonly ILog log = LogManager.GetLogger(typeof(EarthquakeService));           // USGS Data Feeds: http://earthquake.usgs.gov/earthquakes/catalogs/         private const string FeedForPreviousDay =             "http://earthquake.usgs.gov/earthquakes/catalogs/1day-M2.5.xml";         private const string FeedForPreviousWeek =             "http://earthquake.usgs.gov/earthquakes/catalogs/7day-M2.5.xml";           /// <summary>         /// Gets the earthquake data for the previous week.         /// </summary>         /// <returns>A queryable collection of <see cref="Earthquake"/> objects.</returns>         public IQueryable<Earthquake> GetEarthquakes()         {             var feed = GetFeed(FeedForPreviousWeek);             var list = new List<Earthquake>();               if ( feed != null )             {                 foreach ( var entry in feed.Items )                 {                     var quake = CreateEarthquake(entry);                     if ( quake != null )                     {                         list.Add(quake);                     }                 }             }               return list.AsQueryable();         }           /// <summary>         /// Creates an <see cref="Earthquake"/> object for each entry in the Atom feed.         /// </summary>         /// <param name="entry">The Atom entry.</param>         /// <returns></returns>         private Earthquake CreateEarthquake(SyndicationItem entry)         {             Earthquake quake = null;             string title = entry.Title.Text;             string summary = entry.Summary.Text;             string point = GetElementValue<String>(entry, "point");             string depth = GetElementValue<String>(entry, "elev");             string utcTime = null;             string localTime = null;             string depthDesc = null;             double?

Model I have also created a Model folder and added a new class, Earthquake.cs. The Earthquake object will hold the various properties returned from the Atom feed. Here is a sample of the code for that class. Notice the [Key] attribute on the Id property, which is required by RIA Services to uniquely identify the entity. using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ComponentModel.DataAnnotations;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     [DataContract]     public class Earthquake     {         /// <summary>         /// Gets or sets the id.         /// </summary>         /// <value>The id.</value>         [Key]         [DataMember]         public string Id { get; set; }           /// <summary>         /// Gets or sets the title.         /// </summary>         /// <value>The title.</value>         [DataMember]         public string Title { get; set; }           /// <summary>         /// Gets or sets the summary.         /// </summary>         /// <value>The summary.</value>         [DataMember]         public string Summary { get; set; }           // additional properties omitted     } }   View Model The recent trend to use the MVVM pattern for WPF and Silverlight provides a great way to separate the data and behavior logic out of the user interface layer of your client applications. I have chosen to use the MVVM Light Toolkit for the Earthquake Locator, but there are other options out there if you prefer another library. That said, I went ahead and created a ViewModel folder in the Silverlight project and added a EarthquakeViewModel class that derives from ViewModelBase. Here is the code: using System; using System.Collections.ObjectModel; using System.ComponentModel.Composition; using System.ComponentModel.Composition.Hosting; using Microsoft.Maps.MapControl; using GalaSoft.MvvmLight; using EarthquakeLocator.Web.Model; using EarthquakeLocator.Web.Services;   namespace EarthquakeLocator.ViewModel {     /// <summary>     /// Provides data for views displaying earthquake information.     /// </summary>     public class EarthquakeViewModel : ViewModelBase     {         [Import]         public EarthquakeContext Context;

            var container = new CompositionContainer(catalog);             container.ComposeParts(this);             Initialize();         }           /// <summary>         /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class.         /// </summary>         /// <param name="context">The context.</param>         public EarthquakeViewModel(EarthquakeContext context)         {             Context = context;             Initialize();         }           private void Initialize()         {             MapCenter = new Location(20, -170);             ZoomLevel = 2;         }           #region Private Methods           private void OnAutoLoadDataChanged()         {             LoadEarthquakes();

                    }                 }             }, null);         }           #endregion Private Methods           #region Properties           private bool autoLoadData;         /// <summary>         /// Gets or sets a value indicating whether to auto load data.         /// </summary>         /// <value><c>true</c> if auto loading data;

                    RaisePropertyChanged("AutoLoadData");                     OnAutoLoadDataChanged();                 }             }         }           private ObservableCollection<Earthquake> earthquakes;

}             set             {                 if ( mapCenter != value )                 {                     mapCenter = value;                     RaisePropertyChanged("MapCenter");                 }             }         }           private double zoomLevel;         /// <summary>         /// Gets or sets the zoom level.         /// </summary>         /// <value>The zoom level.</value>         public double ZoomLevel         {             get { return zoomLevel; }             set             {                 if ( zoomLevel != value )                 {                     zoomLevel = value;                     RaisePropertyChanged("ZoomLevel");                 }             }         }           #endregion Properties     } }   The EarthquakeViewModel class contains all of the properties that will be bound to by the various controls in our views. Be sure to read through the LoadEarthquakes() method, which handles calling the GetEarthquakes() method in our EarthquakeService via the EarthquakeContext proxy, and also transfers the loaded entities into the view model’s Earthquakes collection. Another thing to notice is what’s going on in the default constructor. I chose to use the Managed Extensibility Framework (MEF) for my composition needs, but you can use any dependency injection library or none at all. To allow the EarthquakeContext class to be discoverable by MEF, I added the following partial class so that I could supply the appropriate [Export] attribute: using System; using System.ComponentModel.Composition;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// The client side proxy for the EarthquakeService class.     /// </summary>     [Export]     public partial class EarthquakeContext     {     } }   One last piece I wanted to point out before moving on to the user interface, I added a client side partial class for the Earthquake entity that contains helper properties that we will bind to later: using System;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     public partial class Earthquake     {         /// <summary>         /// Gets the location based on the current Latitude/Longitude.         /// </summary>         /// <value>The location.</value>         public string Location         {             get { return String.Format("{0},{1}", Latitude, Longitude); }         }           /// <summary>         /// Gets the size based on the Magnitude.         /// </summary>         /// <value>The size.</value>         public double Size         {             get { return (Magnitude * 3); }         }     } }   View Now the fun part! Usually, I would create a Views folder to place all of my View controls in, but I took the easy way out and added the following XAML code to the default MainPage.xaml file. Be sure to add the bing prefix associating the Microsoft.Maps.MapControl namespace after adding the assembly reference to your project. The MVVM Light Toolkit project templates come with a ViewModelLocator class that you can use via a static resource, but I am instantiating the EarthquakeViewModel directly in my user control. I am setting the AutoLoadData property to true as a way to trigger the LoadEarthquakes() method call. The MapItemsControl found within the <bing:Map> control binds its ItemsSource property to the Earthquakes collection of the view model, and since it is an ObservableCollection<T>, we get the automatic two way data binding via the INotifyCollectionChanged interface. <UserControl x:Class="EarthquakeLocator.MainPage"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"     xmlns:vm="clr-namespace:EarthquakeLocator.ViewModel"     mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" >     <UserControl.Resources>         <DataTemplate x:Key="EarthquakeTemplate">             <Ellipse Fill="Red" Stroke="Black" StrokeThickness="1"                      Width="{Binding Size}" Height="{Binding Size}"                      bing:MapLayer.Position="{Binding Location}"                      bing:MapLayer.PositionOrigin="Center">                 <ToolTipService.ToolTip>                     <StackPanel>                         <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" />                         <TextBlock Text="{Binding UtcTime}" />                         <TextBlock Text="{Binding LocalTime}" />                         <TextBlock Text="{Binding DepthDesc}" />                     </StackPanel>                 </ToolTipService.ToolTip>             </Ellipse>         </DataTemplate>     </UserControl.Resources>       <UserControl.DataContext>         <vm:EarthquakeViewModel AutoLoadData="True" />     </UserControl.DataContext>       <Grid x:Name="LayoutRoot">           <bing:Map x:Name="map" CredentialsProvider="--Your-Bing-Maps-Key--"                   Center="{Binding MapCenter, Mode=TwoWay}"                   ZoomLevel="{Binding ZoomLevel, Mode=TwoWay}">             <bing:MapItemsControl ItemsSource="{Binding Earthquakes}"                                   ItemTemplate="{StaticResource EarthquakeTemplate}" />         </bing:Map>       </Grid> </UserControl>   The EarthquakeTemplate defines the Ellipse that will represent each earthquake, the Width and Height that are determined by the Magnitude, the Position on the map, and also the tooltip that will appear when we mouse over each data point. Running the application will give us the following result (shown with a tooltip example): That concludes this portion of our show but I plan on implementing additional functionality in later blog posts. Be sure to come back soon to see the next installments in this series.

• WCF Fails when using impersonation over 2 machine boundaries (3 machines)

  - by MrTortoise

  These scenarios work in their pieces. Its when i put it all together that it breaks. I have a WCF service using netTCP that uses impersonation to get the callers ID (role based security will be used at this level) on top of this is a WCF service using basicHTTP with TransportCredientialOnly which also uses impersonation I then have a client front end that connects to the basicHttp. the aim of the game is to return the clients username from the netTCP service at the bottom - so ultimatley i can use role based security here. each service is on a different machine - and each service works when you remove any calls they make to other services when you run a client for them both locally and remotley. IE the problem only manifests when you jump accross more than one machine boundary. IE the setup breaks when i connect each part together - but they work fine on their own. I also specify [OperationBehavior(Impersonation = ImpersonationOption.Required)] in the method and have IIS setup to only allow windows authentication (actually i have ananymous enabled still, but disabling makes no difference) This impersonation works fine in the scenario where i have a netTCP Service on Machine A with a client with a basicHttp service on machine B with a clinet for the basicHttp service also on machine B ... however if i move that client to any machine C i get the following error: The exception is 'The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:10:00'' the inner message is 'An existing connection was forcibly closed by the remote host' Am beginning to think this is more a network issue than config ... but then im grasping at straws ... the config files are as follows (heading from the client down to the netTCP layer) <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="basicHttpBindingEndpoint" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:10:00" sendTimeout="00:02:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://panrelease01/WCFTopWindowsTest/Service1.svc" binding="basicHttpBinding" bindingConfiguration="basicHttpBindingEndpoint" contract="ServiceReference1.IService1" name="basicHttpBindingEndpoint" behaviorConfiguration="ImpersonationBehaviour" /> </client> <behaviors> <endpointBehaviors> <behavior name="ImpersonationBehaviour"> <clientCredentials> <windows allowedImpersonationLevel="Impersonation"/> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> </configuration> the service for the client (basicHttp service and the client for the netTCP service) <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <bindings> <netTcpBinding> <binding name="netTcpBindingEndpoint" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> <basicHttpBinding> <binding name="basicHttpWindows"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Windows"></transport> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="net.tcp://5d2x23j.panint.com/netTCPwindows/Service1.svc" binding="netTcpBinding" bindingConfiguration="netTcpBindingEndpoint" contract="ServiceReference1.IService1" name="netTcpBindingEndpoint" behaviorConfiguration="ImpersonationBehaviour"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> <behaviors> <endpointBehaviors> <behavior name="ImpersonationBehaviour"> <clientCredentials> <windows allowedImpersonationLevel="Impersonation" allowNtlm="true"/> </clientCredentials> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="WCFTopWindowsTest.basicHttpWindowsBehaviour"> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true" /> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

• Dynamic XAP loading in Task-It - Part 1

  Download Source Code NOTE 1: The source code provided is running against the RC versions of Silverlight 4 and VisualStudio 2010, so you will need to update to those bits to run it. NOTE 2: After downloading the source, be sure to set the .Web project as the StartUp Project, and Default.aspx as the Start Page In my MEF into post, MEF to the rescue in Task-It, I outlined a couple of issues I was facing and explained why I chose MEF (the Managed Extensibility Framework) to solve these issues. Other posts to check out There are a few other resources out there around dynamic XAP loading that you may want to review (by the way, Glenn Block is the main dude when it comes to MEF): Glenn Blocks 3-part series on a dynamically loaded dashboard Glenn and John Papas Silverlight TV video on dynamic xap loading These provide some great info, but didnt exactly cover the scenario I wanted to achieve in Task-Itand that is dynamically loading each of the apps pages the first time the user enters a page. The code In the code I provided for download above, I created a simple solution that shows the technique I used for dynamic XAP loading in Task-It, but without all of the other code that surrounds it. Taking all that other stuff away should make it easier to grasp. Having said that, there is still a fair amount of code involved. I am always looking for ways to make things simpler, and to achieve the desired result with as little code as possible, so if I find a better/simpler way I will blog about it, but for now this technique works for me. When I created this solution I started by creating a new Silverlight Navigation Application called DynamicXAP Loading. I then added the following line to my UriMappings in MainPage.xaml: <uriMapper:UriMapping Uri="/{assemblyName};component/{path}" MappedUri="/{assemblyName};component/{path}"/> In the section of MainPage.xaml that produces the page links in the upper right, I kept the Home link, but added a couple of new ones (page1 and page 2). These are the pages that will be dynamically (lazy) loaded: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}">      <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/>      <Rectangle Style="{StaticResource DividerStyle}"/>      <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/>      <Rectangle Style="{StaticResource DividerStyle}"/>      <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/>  </StackPanel> In App.xaml.cs I added a bit of MEF code. In Application_Startup I call a method called InitializeContainer, which creates a PackageCatalog (a MEF thing), then I create a CompositionContainer and pass it to the CompositionHost.Initialize method. This is boiler-plate MEF stuff that allows you to do 'composition' and import 'packages'. You're welcome to do a bit more MEF research on what is happening here if you'd like, but for the purpose of this example you can just trust that it works. :-) private void Application_Startup(object sender, StartupEventArgs e) {     InitializeContainer();     this.RootVisual = new MainPage(); }   private static void InitializeContainer() {     var catalog = new PackageCatalog();     catalog.AddPackage(Package.Current);     var container = new CompositionContainer(catalog);     container.ComposeExportedValue(catalog);     CompositionHost.Initialize(container); } Infrastructure In the sample code you'll notice that there is a project in the solution called DynamicXAPLoading.Infrastructure. This is simply a Silverlight Class Library project that I created just to move stuff I considered application 'infrastructure' code into a separate place, rather than cluttering the main Silverlight project (DynamicXapLoading). I did this same thing in Task-It, as the amount of this type of code was starting to clutter up the Silverlight project, and it just seemed to make sense to move things like Enums, Constants and the like off to a separate place. In the DynamicXapLoading.Infrastructure project you'll see 3 classes: Enums - There is only one enum in here called ModuleEnum. We'll use these later. PageMetadata - We will use this class later to add metadata to a new dynamically loaded project. ViewModelBase - This is simply a base class for view models that we will use in this, as well as future samples. As mentioned in my MVVM post, I will be using the MVVM pattern throughout my code for reasons detailed in the post. By the way, the ViewModelExtension class in there allows me to do strongly-typed property changed notification, so rather than OnPropertyChanged("MyProperty"), I can do this.OnPropertyChanged(p => p.MyProperty). It's just a less error-prown approach, because if you don't spell "MyProperty" correctly using the first method, nothing will break, it just won't work. Adding a new page We currently have a couple of pages that are being dynamically (lazy) loaded, but now let's add a third page. 1. First, create a new Silverlight Application project: In this example I call it Page3. In the future you may prefer to use a different name, like DynamicXAPLoading.Page3, or even DynamicXAPLoading.Modules.Page3. It can be whatever you want. In my Task-It application I used the latter approach (with 'Modules' in the name). I do think of these application as 'modules', but Prism uses the same term, so some folks may not like that. Use whichever naming convention you feel is appropriate, but for now Page3 will do. When you change the name to Page3 and click OK, you will be presented with the Add New Project dialog: It is important that you leave the 'Host the Silverlight application in a new or existing Web site in the solution' checked, and the .Web project will be selected in the dropdown below. This will create the .xap file for this project under ClientBin in the .Web project, which is where we want it. 2. Uncheck the 'Add a test page that references the application' checkbox, and leave everything else as is. 3. Once the project is created, you can delete App.xaml and MainPage.xaml. 4. You will need to add references your new project to the following: DynamicXAPLoading.Infrastructure.dll (this is a Project reference) DynamicNavigation.dll (this is in the Libs directory under the DynamicXAPLoading project) System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll System.Windows.Controls.Navigation.dll If you have installed the latest RC bits you will find the last 3 dll's under the .NET tab in the Add Referenced dialog. They live in the following location, or if you are on a 64-bit machine like me, it will be Program Files (x86).       C:\Program Files\Microsoft SDKs\Silverlight\v4.0\Libraries\Client Now let's create some UI for our new project. 5. First, create a new Silverlight User Control called Page3.dyn.xaml 6. Paste the following code into the xaml: <dyn:DynamicPageShim xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     xmlns:my="clr-namespace:Page3;assembly=Page3">     <my:Page3Host /> </dyn:DynamicPageShim> This is just a 'shim', part of David Poll's technique for dynamic loading. 7. Expand the icon next to Page3.dyn.xaml and delete the code-behind file (Page3.dyn.xaml.cs). 8. Next we will create a control that will 'host' our page. Create another Silverlight User Control called Page3Host.xaml and paste in the following XAML: <dyn:DynamicPage x:Class="Page3.Page3Host"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     xmlns:Views="clr-namespace:Page3.Views"      mc:Ignorable="d"     d:DesignHeight="300" d:DesignWidth="400"     Title="Page 3">       <Views:Page3/>   </dyn:DynamicPage> 9. Now paste the following code into the code-behind for this control: using DynamicXAPLoading.Infrastructure;   namespace Page3 {     [PageMetadata(NavigateUri = "/Page3;component/Page3.dyn.xaml", Module = Enums.Page3)]     public partial class Page3Host     {         public Page3Host()         {             InitializeComponent();         }     } } Notice that we are now using that PageMetadata custom attribute class that we created in the Infrastructure project, and setting its two properties. NavigateUri - This tells it that the assembly is called Page3 (with a slash beforehand), and the page we want to load is Page3.dyn.xaml...our 'shim'. That line we added to the UriMapper in MainPage.xaml will use this information to load the page. Module - This goes back to that ModuleEnum class in our Infrastructure project. However, setting the Module to ModuleEnum.Page3 will cause a compilation error, so... 10. Go back to that Enums.cs under the Infrastructure project and add a 3rd entry for Page3: public enum ModuleEnum {     Page1,     Page2,     Page3 } 11. Now right-click on the Page3 project and add a folder called Views. 12. Right-click on the Views folder and create a new Silverlight User Control called Page3.xaml. We won't bother creating a view model for this User Control as I did in the Page 1 and Page 2 projects, just for the sake of simplicity. Feel free to add one if you'd like though, and copy the code from one of those other projects. Right now those view models aren't really doing anything anyway...though they will in my next post. :-) 13. Now let's replace the xaml for Page3.xaml with the following: <dyn:DynamicPage x:Class="Page3.Views.Page3"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     mc:Ignorable="d"     d:DesignHeight="300" d:DesignWidth="400"     Style="{StaticResource PageStyle}">       <Grid x:Name="LayoutRoot">         <ScrollViewer x:Name="PageScrollViewer" Style="{StaticResource PageScrollViewerStyle}">             <StackPanel x:Name="ContentStackPanel">                 <TextBlock x:Name="HeaderText" Style="{StaticResource HeaderTextStyle}" Text="Page 3"/>                 <TextBlock x:Name="ContentText" Style="{StaticResource ContentTextStyle}" Text="Page 3 content"/>             </StackPanel>         </ScrollViewer>     </Grid>   </dyn:DynamicPage> 14. And in the code-behind remove the inheritance from UserControl, so it should look like this: namespace Page3.Views {     public partial class Page3     {         public Page3()         {             InitializeComponent();         }     } } One thing you may have noticed is that the base class for the last two User Controls we created is DynamicPage. Once again, we are using the infrastructure that David Poll created. 15. OK, a few last things. We need a link on our main page so that we can access our new page. In MainPage.xaml let's update our links to look like this: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}">     <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 3" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage3}"/> </StackPanel> 16. Next, we need to add the following at the bottom of MainPageViewModel in the ViewModels directory of our DynamicXAPLoading project: public ModuleEnum ModulePage3 {     get { return ModuleEnum.Page3; } } 17. And at last, we need to add a case for our new page to the switch statement in MainPageViewModel: switch (module) {     case ModuleEnum.Page1:         DownloadPackage("Page1.xap");         break;     case ModuleEnum.Page2:         DownloadPackage("Page2.xap");         break;     case ModuleEnum.Page3:         DownloadPackage("Page3.xap");         break;     default:         break; } Now fire up the application and click the page 1, page 2 and page 3 links. What you'll notice is that there is a 2-second delay the first time you hit each page. That is because I added the following line to the Navigate method in MainPageViewModel: Thread.Sleep(2000); // Simulate a 2 second initial loading delay The reason I put this in there is that I wanted to simulate a delay the first time the page loads (as the .xap is being downloaded from the server). You'll notice that after the first hit to the page though that there is no delay...that's because the .xap has already been downloaded. Feel free to comment out this 2-second delay, or remove it if you'd like. I just wanted to show how subsequent hits to the page would be quicker than the initial one. By the way, you may want to display some sort of BusyIndicator while the .xap is loading. I have that in my Task-It appplication, but for the sake of simplicity I did not include it here. In the future I'll blog about how I show and hide the BusyIndicator using events (I'm currently using the eventing framework in Prism for that, but may move to the one in the MVVM Light Toolkit some time soon). Whew, that felt like a lot of steps, but it does work quite nicely. As I mentioned earlier, I'll try to find ways to simplify the code (I'd like to get away from having things like hard-coded .xap file names) and will blog about it in the future if I find a better way. In my next post, I'll talk more about what is actually happening with the code that makes this all work.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• MVVM in Task-It

  As I'm gearing up to write a post about dynamic XAP loading with MEF, I'd like to first talk a bit about MVVM, the Model-View-ViewModel pattern, as I will be leveraging this pattern in my future posts. Download Source Code Why MVVM? Your first question may be, "why do I need this pattern? I've been using a code-behind approach for years and it works fine." Well, you really don't have to make the switch to MVVM, but let me first explain some of the benefits I see for doing so. MVVM Benefits Testability - This is the one you'll probably hear the most about when it comes to MVVM. Moving most of the code from your code-behind to a separate view model class means you can now write unit tests against the view model without any knowledge of a view (UserControl). Multiple UIs - Let's just say that you've created a killer app, it's running in the browser, and maybe you've even made it run out-of-browser. Now what if your boss comes to you and says, "I heard about this new Windows Phone 7 device that is coming out later this year. Can you start porting the app to that device?". Well, now you have to create a new UI (UserControls, etc.) because you have a lot less screen real estate to work with. So what do you do, copy all of your existing UserControls, paste them, rename them, and then start changing the code? Hmm, that doesn't sound so good. But wait, if most of the code that makes your browser-based app tick lives in view model classes, now you can create new view (UserControls) for Windows Phone 7 that reference the same view model classes as your browser-based app. Page state - In Silverlight you're at some point going to be faced with the same issue you dealt with for years in ASP.NET, maintaining page state. Let's say a user hits your Products page, does some stuff (filters record, etc.), then leaves the page and comes back later. It would be best if the Products page was in the same state as when they left it right? Well, if you've thrown away your view (UserControl or Page) and moved off to another part of the UI, when you come back to Products you're probably going to re-instantiate your view...which will put it right back in the state it was when it started. Hmm, not good. Well, with a little help from MEF you can store the state in your view model class, MEF will keep that view model instance hanging around in memory, and then you simply rebind your view to the view model class. I made that sound easy, but it's actually a bit of work to properly store and restore the state. At least it can be done though, which will make your users a lot happier! I'll talk more about this in an upcoming blog post. No event handlers? Another nice thing about MVVM is that you can bind your UserControls to the view model, which may eliminate the need for event handlers in your code-behind. So instead of having a Click handler on a Button (or RadMenuItem), for example, you can now bind your control's Command property to a DelegateCommand in your view model (I'll talk more about Commands in an upcoming post). Instead of having a SelectionChanged event handler on your RadGridView you can now bind its SelectedItem property to a property in your view model, and each time the user clicks a row, the view model property's setter will be called. Now through the magic of binding we can eliminate the need for traditional code-behind based event handlers on our user interface controls, and the best thing is that the view model knows about everything that's going on...which means we can test things without a user interface. The brains of the operation So what we're seeing here is that the view is now just a dumb layer that binds to the view model, and that the view model is in control of just about everything, like what happens when a RadGridView row is selected, or when a RadComboBoxItem is selected, or when a RadMenuItem is clicked. It is also responsible for loading data when the page is hit, as well as kicking off data inserts, updates and deletions. Once again, all of this stuff can be tested without the need for a user interface. If the test works, then it'll work regardless of whether the user is hitting the browser-based version of your app, or the Windows Phone 7 version. Nice! The database Before running the code for this app you will need to create the database. First, create a database called MVVMProject in SQL Server, then run MVVMProject.sql in the MVVMProject/Database directory of your downloaded .zip file. This should give you a Task table with 3 records in it. When you fire up the solution you will also need to update the connection string in web.config to point to your database instead of IBM12\SQLSERVER2008. The code One note about this code is that it runs against the latest Silverlight 4 RC and WCF RIA Services code. Please see my first blog post about updating to the RC bits. Beta to RC - Part 1 At the top of this post is a link to a sample project that demonstrates a sample application with a Tasks page that uses the MVVM pattern. This is a simplified version of how I have implemented the Tasks page in the Task-It application. Youll notice that Tasks.xaml has very little code to it. Just a TextBlock that displays the page title and a ContentControl. <StackPanel>     <TextBlock Text="Tasks" Style="{StaticResource PageTitleStyle}"/>     <Rectangle Style="{StaticResource StandardSpacerStyle}"/>     <ContentControl x:Name="ContentControl1"/> </StackPanel> In List.xaml we have a RadGridView. Notice that the ItemsSource is bound to a property in the view model class call Tasks, SelectedItem is bound to a property in the view model called SelectedItem, and IsBusy is bound to a property in the view model called IsLoading. <Grid>     <telerikGridView:RadGridView ItemsSource="{Binding Tasks}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}"                                  IsBusy="{Binding IsLoading}" AutoGenerateColumns="False" IsReadOnly="True" RowIndicatorVisibility="Collapsed"                IsFilteringAllowed="False" ShowGroupPanel="False">         <telerikGridView:RadGridView.Columns>             <telerikGridView:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}" Width="3*"/>             <telerikGridView:GridViewDataColumn Header="Due" DataMemberBinding="{Binding DueDate}" DataFormatString="{}{0:d}" Width="*"/>         </telerikGridView:RadGridView.Columns>     </telerikGridView:RadGridView> </Grid> In Details.xaml we have a Save button that is bound to a property called SaveCommand in our view model. We also have a simple form (Im using a couple of controls here from Silverlight.FX for the form layout, FormPanel and Label simply because they make for a clean XAML layout). Notice that the FormPanel is also bound to the SelectedItem in the view model (the same one that the RadGridView is). The two form controls, the TextBox and RadDatePicker) are bound to the SelectedItem's Name and DueDate properties. These are properties of the Task object that WCF RIA Services creates. <StackPanel>     <Button Content="Save" Command="{Binding SaveCommand}" HorizontalAlignment="Left"/>     <Rectangle Style="{StaticResource StandardSpacerStyle}"/>     <fxui:FormPanel DataContext="{Binding SelectedItem}" Style="{StaticResource FormContainerStyle}">         <fxui:Label Text="Name:"/>         <TextBox Text="{Binding Name, Mode=TwoWay}"/>         <fxui:Label Text="Due:"/>         <telerikInput:RadDatePicker SelectedDate="{Binding DueDate, Mode=TwoWay}"/>     </fxui:FormPanel> </StackPanel> In the code-behind of the Tasks control, Tasks.xaml.cs, I created an instance of the view model class (TasksViewModel) in the constructor and set it as the DataContext for the control. The Tasks page will load one of two child UserControls depending on whether you are viewing the list of tasks (List.xaml) or the form for editing a task (Details.xaml). // Set the DataContext to an instance of the view model class var viewModel = new TasksViewModel(); DataContext = viewModel;   // Child user controls (inherit DataContext from this user control) List = new List(); // RadGridView Details = new Details(); // Form When the page first loads, the List is loaded into the ContentControl. // Show the RadGridView first ContentControl1.Content = List; In the code-behind we also listen for a couple of the view models events. The ItemSelected event will be fired when the user clicks on a record in the RadGridView in the List control. The SaveCompleted event will be fired when the user clicks Save in the Details control (the form). Here the view model is in control, and is letting the view know when something needs to change. // Listeners for the view model's events viewModel.ItemSelected += OnItemSelected; viewModel.SaveCompleted += OnSaveCompleted; The event handlers toggle the view between the RadGridView (List) and the form (Details). void OnItemSelected(object sender, RoutedEventArgs e) {     // Show the form     ContentControl1.Content = Details; }   void OnSaveCompleted(object sender, RoutedEventArgs e) {     // Show the RadGridView     ContentControl1.Content = List; } In TasksViewModel, we instantiate a DataContext object and a SaveCommand in the constructor. DataContext is a WCF RIA Services object that well use to retrieve the list of Tasks and to save any changes to a task. Ill talk more about this and Commands in future post, but for now think of the SaveCommand as an event handler that is called when the Save button in the form is clicked. DataContext = new DataContext(); SaveCommand = new DelegateCommand(OnSave); When the TasksViewModel constructor is called we also make a call to LoadTasks. This sets IsLoading to true (which causes the RadGridViews busy indicator to appear) and retrieves the records via WCF RIA Services.         public LoadOperation<Task> LoadTasks()         {             // Show the loading message             IsLoading = true;             // Get the data via WCF RIA Services. When the call has returned, called OnTasksLoaded.             return DataContext.Load(DataContext.GetTasksQuery(), OnTasksLoaded, false);         } When the data is returned, OnTasksLoaded is called. This sets IsLoading to false (which hides the RadGridViews busy indicator), and fires property changed notifications to the UI to let it know that the IsLoading and Tasks properties have changed. This property changed notification basically tells the UI to rebind. void OnTasksLoaded(LoadOperation<Task> lo) {     // Hide the loading message     IsLoading = false;       // Notify the UI that Tasks and IsLoading properties have changed     this.OnPropertyChanged(p => p.Tasks);     this.OnPropertyChanged(p => p.IsLoading); } Next lets look at the view models SelectedItem property. This is the one thats bound to both the RadGridView and the form. When the user clicks a record in the RadGridView its setter gets called (set a breakpoint and see what I mean). The other code in the setter lets the UI know that the SelectedItem has changed (so the form displays the correct data), and fires the event that notifies the UI that a selection has occurred (which tells the UI to switch from List to Details). public Task SelectedItem {     get { return _selectedItem; }     set     {         _selectedItem = value;           // Let the UI know that the SelectedItem has changed (forces it to re-bind)         this.OnPropertyChanged(p => p.SelectedItem);         // Notify the UI, so it can switch to the Details (form) page         NotifyItemSelected();     } } One last thing, saving the data. When the Save button in the form is clicked it fires the SaveCommand, which calls the OnSave method in the view model (once again, set a breakpoint to see it in action). public void OnSave() {     // Save the changes via WCF RIA Services. When the save is complete, call OnSaveCompleted.     DataContext.SubmitChanges(OnSaveCompleted, null); } In OnSave, we tell WCF RIA Services to submit any changes, which there will be if you changed either the Name or the Due Date in the form. When the save is completed, it calls OnSaveCompleted. This method fires a notification back to the UI that the save is completed, which causes the RadGridView (List) to show again. public virtual void OnSaveCompleted(SubmitOperation so) {     // Clear the item that is selected in the grid (in case we want to select it again)     SelectedItem = null;     // Notify the UI, so it can switch back to the List (RadGridView) page     NotifySaveCompleted(); } Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• WCF contract mismatch problem

  - by Tom

  Hi there, I have a client console app talking to a WCF service and I get the following error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error." I think it's becuase of a contract mismatch but i can't figure out why. The service runs just fine by itself and the 2 parts were working together until i added the impersonation code. Can anyone see what is wrong? Here is the client, all done in code: NetTcpBinding binding = new NetTcpBinding(); binding.Security.Mode = SecurityMode.Message; binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows; EndpointAddress endPoint = new EndpointAddress(new Uri("net.tcp://serverName:9990/TestService1")); ChannelFactory<IService1> channel = new ChannelFactory<IService1>(binding, endPoint); channel.Credentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation; IService1 service = channel.CreateChannel(); And here is the config file of the WCF service: <configuration> <system.serviceModel> <bindings> <netTcpBinding> <binding name="MyBinding"> <security mode="Message"> <transport clientCredentialType="Windows"/> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="WCFTest.ConsoleHost2.Service1Behavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceAuthorization impersonateCallerForAllOperations="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="WCFTest.ConsoleHost2.Service1Behavior" name="WCFTest.ConsoleHost2.Service1"> <endpoint address="" binding="wsHttpBinding" contract="WCFTest.ConsoleHost2.IService1"> <identity> <dns value="" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <endpoint binding="netTcpBinding" bindingConfiguration="MyBinding" contract="WCFTest.ConsoleHost2.IService1" /> <host> <baseAddresses> <add baseAddress="http://serverName:9999/TestService1/" /> <add baseAddress="net.tcp://serverName:9990/TestService1/" /> </baseAddresses> </host> </service> </services> </system.serviceModel> </configuration>

• JQTOUCH, Binding to links pulled in via AJAX, to make another AJAX call? Possible?

  - by nobosh

  Hello. I'm using JQTOUCH using the AJAX example provided in the demo: $('#customers').bind('pageAnimationEnd', function(e, info){ if (!$(this).data('loaded')) { // Make sure the data hasn't already been loaded (we'll set 'loaded' to true a couple lines further down) $('.loadingscreen').css({'display':'block'}); $(this).append($('<div> </div>'). // Append a placeholder in case the remote HTML takes its sweet time making it back load('/mobile/ajax/customers/ .info', function() { // Overwrite the "Loading" placeholder text with the remote HTML $(this).parent().data('loaded', true); // Set the 'loaded' var to true so we know not to re-load the HTML next time the #callback div animation ends $('.loadingscreen').css({'display':'none'}); })); } }); This then returns a nice UL which outputs just fine.. <ul class="edgetoedge"> <li class="viewaction" id="715"> <span class="Title"><a href="/c-view/715/">Lorem Ipsum is simply dummy text of the...</a></span> <div class="meta"> <span class="dateAdded"> 1d ago </span> </div> </li> </ul> This is where I get stuck. How can I then make it so when you click on the link above, it loads the URL wrapped near the class="Title" ? I'd like it to load JQTouch like the first code example. I tried the following two things without success: $('.viewaction').bind('click', function() { alert('wow'); }); $('.viewaction').live('pageAnimationEnd', function(e, info){ }); Thank you!

• NSObjectController confusion binding to a class property. Help!

  - by scottw

  Hi, I'm teaching myself cocoa and enjoying the experience most of the time. I have been struggling all day with a simple problem that google has let me down on. I have read the Cocoa Bindings Program Topics and think I grok it but still can't solve my issue. I have a very simple class called MTSong that has various properties. I have used @synthesize to create getter/setters and can use KVC to change properties. i.e in my app controller the following works: mySong = [[MTSong alloc]init]; [mySong setValue:@"2" forKey:@"version"]; In case I am doing something noddy in my class code MTSong.h is: #import <Foundation/Foundation.h> @interface MTSong : NSObject { NSNumber *version; NSString *name; } @property(readwrite, assign) NSNumber *version; @property(readwrite, assign) NSString *name; @end and MTSong.m is: #import "MTSong.h" @implementation MTSong - (id)init { [super init]; return self; } - (void)dealloc { [super dealloc]; } @synthesize version; @synthesize name; @end In Interface Builder I have a label (NSTextField) that I want to update whenever I use KVC to change the version of the song. I do the following: Drag NSObjectController object into the doc window and in the Inspector-Attributes I set: Mode: Class Class Name: MTSong Add a key called version and another called name Go to Inspector-Bindings-Controller Content Bind To: File's Owner (Not sure this is right...) Model Key Path: version Select the cell of the label and go to Inspector Bind to: Object Controller Controller Key: mySong Model Key Path: version I have attempted changing the Model Key Path in step 2 to "mySong" which makes more sense but the compiler complains. Any suggestions would be greatly appreciated. Scott Update Post Comments I wasn't exposing mySong property so have changed my AppController.h to be: #import <Cocoa/Cocoa.h> @class MTSong; @interface AppController : NSObject { IBOutlet NSButton *start; IBOutlet NSTextField *tf; MTSong *mySong; } -(IBAction)convertFile:(id)sender; @end I suspect File's owner was wrong as I am not using a document based application and I need to bind to the AppController, so step 2 is now: Go to Inspector-Bindings-Controller Content Bind To: App Controller Model Key Path: mySong I needed to change 3. to Select the cell of the label and go to Inspector Bind to: Object Controller Controller Key: selection Model Key Path: version All compiles and is playing nice!

• WPF: Focus in a Window and UserControl

  - by Echilon

  I'm trying to get a UserControl to tab properly and am baffled. The logical tree looks like this. |-Window -Grid -TabControl -TabItem -StackPanel -MyUserControl |-StackPanel -GroupBox -Grid -ComboBox -Textbox1 -Textbox2 Everything works fine, except when the visibility converter for the ComboBox returns Visibility.Collapsed (don't allow user to change database mode), then when textbox1 is selected, instead of being able to tab through the controls in the UserControl, the focus shifts to a button declared at the bottom of the window. Nothing else apart from the controls displayed has TabIndex or FocusManager properties set. I'm banging my head against a brick wall and I must be missing something. I've tried IsFocusScope=True/False, played with FocusedElement and nothing works if that ComboBox is invisible (Visibility.Collapsed). <Window x:Class="MyNamespace.Client.WinInstaller" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" FocusManager.FocusedElement="{Binding ElementName=tabWizard}"> <Window.Resources> <props:Settings x:Key="settings" /> </Window.Resources> <Grid Grid.IsSharedSizeScope="True"> <!-- row and column definitions omitted --> <loc:SmallHeader Grid.Row="0" x:Name="headerBranding" HeaderText="Setup" /> <TabControl x:Name="tabWizard" DataContext="{StaticResource settings}" SelectedIndex="0" FocusManager.IsFocusScope="True"> <TabItem x:Name="tbStart" Height="0"> <StackPanel> <TextBlock Text="Database Mode"/> <loc:DatabaseSelector x:Name="dbSelector" AllowChangeMode="False" TabIndex="1" AvailableDatabaseModes="SQLServer" IsPortRequired="False" DatabaseMode="{Binding Default.DbMode,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" DatabasePath="{Binding Default.DatabasePath,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"/> </StackPanel> </TabItem> ...

  I'm still experimenting with DynamicObjects. Now I need some information: I'm trying to bind an object inheriting from DynamicObject to a WPF DataGrid (not Silverlight). How do I get the DataGrid to automatically create its columns from the available public properties of the object that are typically generated at runtime? Is that possible actually?

• Generic structure for performing string conversion when data binding.

  - by Rohan West

  Hi there, a little while ago i was reading an article about a series of class that were created that handled the conversion of strings into a generic type. Below is a mock class structure. Basically if you set the StringValue it will perform some conversion into type T public class MyClass<T> { public string StringValue {get;set;} public T Value {get;set;} } I cannot remember the article that i was reading, or the name of the class i was reading about. Is this already implemented in the framework? Or shall i create my own?

• Use XAML data binding to bind each end of a Line to the center of two shapes on a Canvas

  - by spoon16

  I have a Canvas in Silverlight with two ellipses on it. The ellipses are animated via events in the code behind. I have added a line two the canvas and I would like each end of the line to be bound to the center of each ellipse. Is it possible to do this in XAML databinding or will I have to manually move the end of the line around in code?

• Binding DataTable To GridView, But No Rows In GridViewRowCollection Despite GridView Population?

  - by KSwift87

  Problem: I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.) GridView Markup: <asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID"> <Columns> <asp:BoundField DataField="ProductID" HeaderText="ProductID" /> <asp:BoundField DataField="Name" HeaderText="ProductName" /> <asp:ImageField DataImageUrlField="Thumbnail" HeaderText="Thumbnail"></asp:ImageField> <asp:BoundField DataField="Unit Price" HeaderText="Unit Price" /> <asp:TemplateField HeaderText="Quantity"> <ItemTemplate> <asp:TextBox ID="Quantity" runat="server" Text="<%# Bind('Quantity') %>" Width="25px"></asp:TextBox> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Total Price" HeaderText="Total Price" /> </Columns> </asp:GridView> DataTable Code-Behind: private void View(List<OrderItem> cart) { DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Cart"); if (cart != null) { dt.Columns.Add("ProductID"); dt.Columns.Add("Name"); dt.Columns.Add("Thumbnail"); dt.Columns.Add("Unit Price"); dt.Columns.Add("Quantity"); dt.Columns.Add("Total Price"); foreach (OrderItem item in cart) { DataRow dr = dt.NewRow(); dr["ProductID"] = item.productId.ToString(); dr["Name"] = item.productName; dr["Thumbnail"] = ResolveUrl(item.productThumbnail); dr["Unit Price"] = "$" + item.productPrice.ToString(); dr["Quantity"] = item.productQuantity.ToString(); dr["Total Price"] = "$" + (item.productPrice * item.productQuantity).ToString(); dt.Rows.Add(dr); } gvCart.DataSource = dt; gvCart.DataBind(); gvCart.Width = 500; for (int counter = 0; counter < gvCart.Rows.Count; counter++) { gvCart.Rows[counter].Cells.Add(Common.createCell("<a href='cart.aspx?action=update&prodId=" + gvCart.Rows[counter].Cells[0].Text + "'>Update</a><br /><a href='cart.aspx?action='action=remove&prodId=" + gvCart.Rows[counter].Cells[0].Text + "/>Remove</a>")); } } } Error occurs below in the foreach - the GridViewRowCollection is empty! private void Update(string prodId) { List<OrderItem> cart = (List<OrderItem>)Session["cart"]; int uQty = 0; foreach (GridViewRow gvr in gvCart.Rows) { if (gvr.RowType == DataControlRowType.DataRow) { if (gvr.Cells[0].Text == prodId) { uQty = int.Parse(((TextBox)gvr.Cells[4].FindControl("Quantity")).Text); } } } Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.

• Why won't binding to a child object property with rdlc Report work in vs2010?

  - by andrej351

  A while ago someone asked how to bind to a child object's property in a rdlc report. Question here. The solution was to use an expression like this: =Fields!ChildObject.Value.SomeProperty I have recently tried to upgrade to version 10 of the reporting libraries (Microsoft.ReportViewer.WebForms and Microsoft.ReportViewer.Common) and for some reason this does not work anymore. I have got the report rendering and displaying all data fine except any which uses this technique. Instead of the property value i get the text: "#Error" Why doesn't this work anymore? Anybody know how to to this in the new version?

• How to set a key binding to make Emacs as transparent/opaque as I want?

  - by Vivi

  I want to have a command in Emacs to make it as opaque/transparent as I want (refer to the fabulous question that pointed out that transparency is possible in Emacs, and the EmacsWiki page linked there which has the code I am using below). The EmacsWiki code sets "C-c t" to toggle the previously set transparency on and off: ;;(set-frame-parameter (selected-frame) 'alpha '(<active> [<inactive>])) (set-frame-parameter (selected-frame) 'alpha '(85 50)) (add-to-list 'default-frame-alist '(alpha 85 50)) enter code here(eval-when-compile (require 'cl)) (defun toggle-transparency () (interactive) (if (/= (cadr (find 'alpha (frame-parameters nil) :key #'car)) 100) (set-frame-parameter nil 'alpha '(100 100)) (set-frame-parameter nil 'alpha '(85 60)))) (global-set-key (kbd "C-c t") 'toggle-transparency) What I would like to do is to be able to choose the % transparency when I am in Emacs. If possible, I would like a command where I type for example "C-c t N" (where N is the % opaqueness) for the active frame, and then "M-c t N" for the inactive window. If that can't be done like that, then maybe a command where if I type "C-c t" it asks me for the number which gives the opaqueness of the active window (and the same for the inactive window using "M-c t"). Thanks in advance for your time :) Below are just some comments that are not important to answer the question if you are not interested: I really want this because when I told my supervisor I was learning Emacs he said TexShop is much better and that I am using software from the 80's. I told him about the wonders of Emacs and he said TexShop has all of it and more. I matched everything he showed me except for the transparency (though he couldn't match the preview inside Emacs from preview-latex). I found the transparency thing by chance, and now I want to show him Emacs rules! I imagine this will be a piece of cake for some of you, and even though I could get it done if I spent enough time trying to learn lisp or reading around, I am not a programmer and I have only been using Emacs and a mac for a week. I am lost already as it is! So thanks in advance for your time and help - I will learn lisp eventually!

• Why is e.Item.DataItem null on ItemDataBound event when binding an asp:net Repeater to a Collection?

  - by Clean

  Hi, I'm trying to bind a collection implementing the ICollection, IEnumerable and IList interface to an asp.net repeater. The Collection is named CustomCollection. So I'm setting the datasource of the repeater to the collection, as follows: rptRepeater.DataSource = customCollection; rptRepeater.Databind(); Then, on the ItemDataBound event, I'm trying to access the DataItem object, as follow: void rptRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e){ object obj = e.Item.DataItem; // DataItem is null for some reason } For some reason the e.Item.DataItem object is null. Do anyone know why this is, and/or what I could do to get hold of the object in the collection that is to be databound to the repeater? Thanx!

• EADDRNOTAVAIL when binding 127.0.0.1 on localhost?

  - by Jonas Byström

  I'm getting errno==49 (EADDRNOTAVAIL) when trying to UDP-bind() to 127.0.0.1:47346 running Mac OS X on a G5 (big endian PowerPC). Is there something preventing me from doing so? I've tried other addresses and ports (192.168.1.2 and port 47346) but with no success. Here's a gdb printout of my sockaddr_in: $1 = { sin_len = 0 '\0', sin_family = 2 '\002', sin_port = 47346, sin_addr = { s_addr = 3232235778 }, sin_zero = "???\000\000??" }

• How do I prevent JAXB from binding superclass methods of the @XmlRootElement when marshalling?

  - by Matt Fisher

  I have a class that is annotated as the @XmlRootElement with @XmlAccessorType(XmlAccessType.NONE). The problem that I am having is that the superclass's methods are being bound, when I do not want them to be bound, and cannot update the class. I am hoping there is an annotation that I can put on the root element class to prevent this from happening. Example: @XmlRootElement @XmlAccessorType(XmlAccessType.NONE) public class Person extends NamedObject { @XmlElement public String getId() { ... } } I would expect that only the methods annotated @XmlElement on Person would be bound and marshalled, but the superclass's methods are all being bound, as well. The resulting XML then has too much information. How do I prevent the superclass's methods from being bound without having to annotate the superclass, itself?

• What is the best approach to binding commands in a ViewModel to elements in the View?

  - by Micah

  Anyone who has tried to implement RoutedCommands in WPF using M-V-VM has undoubtedly run into issues. Commands (non-UI commands that is) should be implemented in the ViewModel. For instance if I needed to save a CustomerViewModel then I would implement that as a command directly on my CustomerViewModel. However if I wanted to pop up a window to show the users addresses I would implement a ShowCustomerAddress command directly in the view since this a UI specific function. How do I define the command bindings in the viewmodel, and use them in the view?
