  • ObservableCollection Implementation

    - by wpfwannabe
    I know I am missing something obvious but I can't seem to implement ObservableCollection in my class below. IE it won't show up in intellsense. Can someone please let me know what I am missing. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Collections; using System.Collections.ObjectModel; using System.Reflection; using System.ComponentModel; namespace MyBTOList { public class InventoryListBTO : List<InventoryBTO> { /// <summary> /// Get all inventory records from local database /// </summary> /// <returns></returns> public static InventoryListBTO GetAllInventoryRecords() { return GetInventoryListBO(Inventory.GetAllInventoryRecordsDb()); } } public class InventoryBTO : INotifyPropertyChanged { }

  • Reflection PropertyInfo GetValue call errors out for Collection<> type property.

    - by Vinit Sankhe
    Hey Guys, I have a propertyInfo object and I try to do a GetValue using it. object source = mysourceObject //This object has a property "Prop1" of type Collection<>. var propInfo = source.GetType().GetProperty("Prop1"); var propValue = prop.GetValue(this, null); // do whatever with propValue // ... I get error at the GetValue() call as "Value cannot be null.\r\nParameter name: source" "Prop1" is a plain property declared as Collection. prop.PropertyType = {Name = "Collection1" FullName = "System.Collections.ObjectModel.Collection1[[Application1.DummyClass, Application1, Version=1.5.5.5834, Culture=neutral, PublicKeyToken=628b2ce865838339]]"} System.Type {System.RuntimeType}

  • How to prevent UI from freezing during lengthy process?

    - by OverTheRainbow
    Hello, I need to write a VB.Net 2008 applet to go through all the fixed-drives looking for some files. If I put the code in ButtonClick(), the UI freezes until the code is done: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'TODO Find way to avoid freezing UI while scanning fixed drives Dim drive As DriveInfo Dim filelist As Collections.ObjectModel.ReadOnlyCollection(Of String) Dim filepath As String For Each drive In DriveInfo.GetDrives() If drive.DriveType = DriveType.Fixed Then filelist = My.Computer.FileSystem.GetFiles(drive.ToString, FileIO.SearchOption.SearchAllSubDirectories, "MyFiles.*") For Each filepath In filelist 'Do stuff Next filepath End If Next drive End Sub Google returned information on a BackGroundWorker control: Is this the right/way to solve this issue? If not, what solution would you recommend, possibly with a really simple example? FWIW, I read that Application.DoEvents() is a left-over from VBClassic and should be avoided. Thank you.

  • using Generics in C# [closed]

    - by Uphaar Goyal
    I have started looking into using generics in C#. As an example what i have done is that I have an abstract class which implements generic methods. these generic methods take a sql query, a connection string and the Type T as parameters and then construct the data set, populate the object and return it back. This way each business object does not need to have a method to populate it with data or construct its data set. All we need to do is pass the type, the sql query and the connection string and these methods do the rest.I am providing the code sample here. I am just looking to discuss with people who might have a better solution to what i have done. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Data.SqlClient; using MWTWorkUnitMgmtLib.Business; using System.Collections.ObjectModel; using System.Reflection; namespace MWTWorkUnitMgmtLib.TableGateway { public abstract class TableGateway { public TableGateway() { } protected abstract string GetConnection(); protected abstract string GetTableName(); public DataSet GetDataSetFromSql(string connectionString, string sql) { DataSet ds = null; using (SqlConnection connection = new SqlConnection(connectionString)) using (SqlCommand command = connection.CreateCommand()) { command.CommandText = sql; connection.Open(); using (ds = new DataSet()) using (SqlDataAdapter adapter = new SqlDataAdapter(command)) { adapter.Fill(ds); } } return ds; } public static bool ContainsColumnName(DataRow dr, string columnName) { return dr.Table.Columns.Contains(columnName); } public DataTable GetDataTable(string connString, string sql) { DataSet ds = GetDataSetFromSql(connString, sql); DataTable dt = null; if (ds != null) { if (ds.Tables.Count 0) { dt = ds.Tables[0]; } } return dt; } public T Construct(DataRow dr, T t) where T : class, new() { Type t1 = t.GetType(); PropertyInfo[] properties = t1.GetProperties(); foreach (PropertyInfo property in properties) { if (ContainsColumnName(dr, property.Name) && (dr[property.Name] != null)) property.SetValue(t, dr[property.Name], null); } return t; } public T GetByID(string connString, string sql, T t) where T : class, new() { DataTable dt = GetDataTable(connString, sql); DataRow dr = dt.Rows[0]; return Construct(dr, t); } public List GetAll(string connString, string sql, T t) where T : class, new() { List collection = new List(); DataTable dt = GetDataTable(connString, sql); foreach (DataRow dr in dt.Rows) collection.Add(Construct(dr, t)); return collection; } } }

  • F# WPF Form &ndash; the basics

    - by MarkPearl
    I was listening to Dot Net Rocks show #560 about F# and during the podcast Richard Campbell brought up a good point with regards to F# and a GUI. In essence what I understood his point to be was that until one could write an end to end application in F#, it would be a hard sell to developers to take it on. In part I agree with him, while I am beginning to really enjoy learning F#, I can’t but help feel that I would be a lot further into the language if I could do my Windows Forms like I do in C# or VB.NET for the simple reason that in “playing” applications I spend the majority of the time in the UI layer… So I have been keeping my eye out for some examples of creating a WPF form in a F# project and came across Tim’s F# Twitter Stream Sample, which had exactly this…. of course he actually had a bit more than a basic form… but it was enough for me to scrap the insides and glean what I needed. So today I am going to make just the very basic WPF form with all the goodness of a XAML window. Getting Started First thing we need to do is create a new solution with a blank F# application project – I have made mine called FSharpWPF. Once you have the project created you will need to change the project type from a Console Application to a Windows Application. You do this by right clicking on the project file and going to its properties… Once that is done you will need to add the appropriate references. You do this by right clicking on the References in the Solution Explorer and clicking “Add Reference'”. You should add the appropriate .Net references below for WPF & XAMl to work. Once these references are added you then need to add your XAML file to the project. You can do this by adding a new item to the project of type xml and simply changing the file extension from xml to xaml. Once the xaml file has been added to the project you will need to add valid window XAML. Example of a very basic xaml file is shown below… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF WPF Form" Height="350" Width="525"> <Grid> </Grid> </Window> Once your xaml file is done… you need to set the build action of the xaml file from “None” to “Resource” as depicted in the picture below. If you do not set this you will get an IOException error when running the completed project with a message along the lines of “Cannot locate resource ‘window.xaml’ You then need to tie everything up by putting the correct F# code in the Program.fs to load the xaml window. In the Program.fs put the following code… module Program open System open System.Collections.ObjectModel open System.IO open System.Windows open System.Windows.Controls open System.Windows.Markup [<STAThread>] [<EntryPoint>] let main(_) = let w = Application.LoadComponent(new System.Uri("/FSharpWPF;component/Window.xaml", System.UriKind.Relative)) :?> Window (new Application()).Run(w) Once all this is done you should be able to build and run your project. What you have done is created a WPF based window inside a FSharp project. It should look something like below…   Nothing to exciting, but sufficient to illustrate the very basic WPF form in F#. Hopefully in future posts I will build on this to expose button events etc.

  • Implementing Search for BlogReader Windows 8 Sample

    - by Harish Ranganathan
    The BlogReader sample is an excellent place to start speeding up your Windows 8 development skills.  The tutorial is available here and the complete source code is available here Create a project called WindowsBlogReader and create pages for ItemsPage.xaml, SplitPage.xaml and DetailPage.xaml and copy the corresponding code blocks from the sample listed above. Created a class file FeedData.cs and copy the code.  Finally, create a class DateConverter.cs and copy the code associated with it. With that you should be able to build and run the project.  There seems to be one issue in the sample feeds listed that the first week (feed1) doesn’t seem to expose it.  So you can skip that and use the second feed as first feed.  You will end up with one feed less but it works. I had demonstrated this in the recent TechDays at Chennai.  How we can use the Search Contract and implement Search for within the Blog Titles. First off, we need to declare that the App will be using Search Contract, in the Package.appmanifest file Next, we would need a handle of the Search Contract when user types on the search window in Charms Menu. If you had completed the code sample from the link above, you would have ItemsPage.xaml and ItemsPage.xaml.cs.  Open the ItemsPage.xaml.cs. Import the namespaces using System.Collections.ObjectModel and System.Linq. in the ItemsPage() constructor, right after this.InitializeComponent(); add the following code Windows.ApplicationModel.Search.SearchPane.GetForCurrentView().QuerySubmitted += ItemsPage_QuerySubmitted; This event is fired when users open up the Search Panel from Charms Menu, type something and hit enter. We need to handle this event declared in the delegate.  For that we need to pull the FeedDataSource instantiation to the root of the class to make it global. So, add the following as the first line within the partial class FeedDataSource feedDataSource; Also, modify the LoadState method, as follows:- protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)        {            feedDataSource = (FeedDataSource)App.Current.Resources["feedDataSource"];            if (feedDataSource != null)            {                this.DefaultViewModel["Items"] = feedDataSource.Feeds;            }        } Next is to implement the ItemsPage_QuerySubmitted method void ItemsPage_QuerySubmitted(Windows.ApplicationModel.Search.SearchPane sender, Windows.ApplicationModel.Search.SearchPaneQuerySubmittedEventArgs args)         {             this.DefaultViewModel["Items"] = from dynamic item in feedDataSource.Feeds                                              where                                              item.Title.Contains(args.QueryText)                                              select item;         } As you can see we are almost using the same defaultviewmodel with the change that we are using a linq query to do a search on feeds which has the Title that matches QueryText. With this we are ready to run the app. Run the App.  Hit the Charms Menu with Windows + C key combination and type a text to search within the blog. You can see that it filters the Blogs which has the matching text. We can modify the above Linq query to do a search for the Text in other attributes like description, actual blog content etc., I have uploaded the complete code since the original WindowsBlogReader Code is not available for download.  You can download it from here note:  this code is provided as-is without any warranties.  Cheers!!!

  • Moq for Silverlight doesn't raise event

    - by Budda
    Trying to write Unit test for Silverlight 4.0 using Moq 4.0.10531.7 public delegate void DataReceived(ObservableCollection<TeamPlayerData> AllReadyPlayers, GetSquadDataCompletedEventArgs squadDetails); public interface ISquadModel : IModelBase { void RequestData(int matchId, int teamId); void SaveData(); event DataReceived DataReceivedEvent; } void MyTest() { Mock<ISquadModel> mockSquadModel = new Mock<ISquadModel>(); mockSquadModel.Raise(model => model.DataReceivedEvent += null, EventArgs.Empty); } Instead of raising the 'DataReceivingEvent' the following error is received: Object of type 'Castle.Proxies.ISquadModelProxy' cannot be converted to type 'System.Collections.ObjectModel.ObservableCollection`1[TeamPlayerData]'. Why attempt to convert mock to the type of 1st event parameter is performed? How can I raise an event? I've also tried another approach: mockSquadModel .Setup(model => model.RequestData(TestMatchId, TestTeamId)) .Raises(model => model.DataReceivedEvent += null, EventArgs.Empty) ; this should raise event if case somebody calls 'Setup' method... Instead the same error is generated... Any thoughts are welcome. Thanks

  • Problem with persisting a collection, that references an internal property, at design time in winfor

    - by Jules
    ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code: Public Class Anger End Class Public Class MyButton Inherits Button Private _Annoyance As List(Of Anger) <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As List(Of Anger) Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New List(Of Anger) Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class The designer screws up the persistence code in the same way as the original problem. ---- Original Problem The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • XmlSerialize a custom collection with an Attribute

    - by roomaroo
    I've got a simple class that inherits from Collection and adds a couple of properties. I need to serialize this class to XML, but the XMLSerializer ignores my additional properties. I assume this is because of the special treatment that XMLSerializer gives ICollection and IEnumerable objects. What's the best way around this? Here's some sample code: using System.Collections.ObjectModel; using System.IO; using System.Xml.Serialization; namespace SerialiseCollection { class Program { static void Main(string[] args) { var c = new MyCollection(); c.Add("Hello"); c.Add("Goodbye"); var serializer = new XmlSerializer(typeof(MyCollection)); using (var writer = new StreamWriter("test.xml")) serializer.Serialize(writer, c); } } [XmlRoot("MyCollection")] public class MyCollection : Collection<string> { [XmlAttribute()] public string MyAttribute { get; set; } public MyCollection() { this.MyAttribute = "SerializeThis"; } } } This outputs the following XML (note MyAttribute is missing in the MyCollection element): <?xml version="1.0" encoding="utf-8"?> <MyCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>Hello</string> <string>Goodbye</string> </MyCollection> What I want is <MyCollection MyAttribute="SerializeThis" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>Hello</string> <string>Goodbye</string> </MyCollection> Any ideas? The simpler the better. Thanks.

  • Using LINQ on observable with GroupBy and Sum aggregate

    - by Mark Oates
    I have the following block of code which works fine; var boughtItemsToday = (from DBControl.MoneySpent bought in BoughtItemDB.BoughtItems select bought); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(boughtItemsToday); It returns data from my MoneySpent table which includes ItemCategory, ItemAmount, ItemDateTime. I want to change it to group by ItemCategory and ItemAmount so I can see where I am spending most of my money, so I created a GroupBy query, and ended up with this; var finalQuery = boughtItemsToday.AsQueryable().GroupBy(category => category.ItemCategory); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(finalQuery); Which gives me 2 errors; Error 1 The best overloaded method match for 'System.Collections.ObjectModel.ObservableCollection.ObservableCollection(System.Collections.Generic.List)' has some invalid arguments Error 2 Argument 1: cannot convert from 'System.Linq.IQueryable' to 'System.Collections.Generic.List' And this is where I'm stuck! How can I use the GroupBy and Sum aggregate function to get a list of my categories and the associated spend in 1 LINQ query?! Any help/suggestions gratefully received. Mark

  • Service behavior not being applied correctly

    - by Rubans
    I have a custom behavior for a service where I want to specify a receive timeout value, I have created a behavior and on the build service header. I use the declarative attribute to apply the behavior or as I thought. But the behavior seems to make no difference, i.e. the set timeout value is not being applied as expected. However when I have noticed the behavior is only being applied when the host is opened rather than when created. The same behavior when applied explicitly through does work. Any ideas? Behavior: [AttributeUsage(AttributeTargets.Class)] public class BuildServiceBindingBehavior : Attribute, IServiceBehavior { public BuildServiceBindingBehavior( string p_receiveTime ) { ReceiveTimeout = TimeSpan.Parse( p_receiveTime ); } #region IServiceBehavior Members public void AddBindingParameters( ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters ) { } public void ApplyDispatchBehavior( ServiceDescription serviceDescription, ServiceHostBase serviceHostBase ) { // add this behavior to each endpoint foreach ( var endPoint in serviceDescription.Endpoints ) { endPoint.Binding.ReceiveTimeout = ReceiveTimeout; } } public void Validate( ServiceDescription serviceDescription, ServiceHostBase serviceHostBase ) { } #endregion internal TimeSpan ReceiveTimeout { get; set; } } Service code: [ServiceBehavior(Name = "DotNetBuildsService", InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Single )] // Set receieve time out [BuildServiceBindingBehavior( "0:0:1" )] public class BuildService : IBuildTasksService { //implementation code }

  • International Radio Operators Alphabet in F# &amp; Silverlight &ndash; Part 2

    - by MarkPearl
    So the brunt of my my very complex F# code has been done. Now it’s just putting the Silverlight stuff in. The first thing I did was add a new project to my solution. I gave it a name and VS2010 did the rest of the magic in creating the .Web project etc. In this instance because I want to take the MVVM approach and make use of commanding I have decided to make the frontend a Silverlight4 project. I now need move my F# code into a proper Silverlight Library. Warning – when you create the Silverlight Library VS2010 will ask you whether you want it to be based on Silverlight3 or Silverlight4. I originally went for Silverlight4 only to discover when I tried to compile my solution that I was given an error… Error 12 F# runtime for Silverlight version v4.0 is not installed. Please go to http://go.microsoft.com/fwlink/?LinkId=177463 to download and install matching.. After asking around I discovered that the Silverlight4 F# runtime is not available yet. No problem, the suggestion was to change the F# Silverlight Library to a Silverlight3 project however when going to the properties of the project file – even though I changed it to Silverlight3, VS2010 did not like it and kept reverting it to a Silverlight4 project. After a few minutes of scratching my head I simply deleted Silverlight4 F# Library project and created a new F# Silverlight Library project in Silverlight3 and VS2010 was happy. Now that the project structure is set up, rest is fairly simple. You need to add the Silverlight Library as a reference to the C# Silverlight Front End. Then setup your views, since I was following the MVVM pattern I made a Views & ViewModel folder and set up the relevant View and ViewModels. The MainPageViewModel file looks as follows using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.Collections.ObjectModel; namespace IROAFrontEnd.ViewModels { public class MainPageViewModel : ViewModelBase { private string _iroaString; private string _inputCharacters; public string InputCharacters { get { return _inputCharacters; } set { if (_inputCharacters != value) { _inputCharacters = value; OnPropertyChanged("InputCharacters"); } } } public string IROAString { get { return _iroaString; } set { if (_iroaString != value) { _iroaString = value; OnPropertyChanged("IROAString"); } } } public ICommand MySpecialCommand { get { return new MyCommand(this); } } public class MyCommand : ICommand { readonly MainPageViewModel _myViewModel; public MyCommand(MainPageViewModel myViewModel) { _myViewModel = myViewModel; } public event EventHandler CanExecuteChanged; public bool CanExecute(object parameter) { return true; } public void Execute(object parameter) { var result = ModuleMain.ConvertCharsToStrings(_myViewModel.InputCharacters); var newString = ""; foreach (var Item in result) { newString += Item + " "; } _myViewModel.IROAString = newString.Trim(); } } } } One of the features I like in Silverlight4 is the new commanding. You will notice in my I have put the code under the command execute to reference to my F# module. At the moment this could be cleaned up even more, but will suffice for now.. public void Execute(object parameter) { var result = ModuleMain.ConvertCharsToStrings(_myViewModel.InputCharacters); var newString = ""; foreach (var Item in result) { newString += Item + " "; } _myViewModel.IROAString = newString.Trim(); } I then needed to set the view up. If we have a look at the MainPageView.xaml the xaml code will look like the following…. Nothing to fancy, but battleship grey for now… take careful note of the binding of the command in the button to MySpecialCommand which was created in the ViewModel. <UserControl x:Class="IROAFrontEnd.Views.MainPageView" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBox Grid.Row="0" Text="{Binding InputCharacters, Mode=TwoWay}"/> <Button Grid.Row="1" Command="{Binding MySpecialCommand}"> <TextBlock Text="Generate"/> </Button> <TextBlock Grid.Row="2" Text="{Binding IROAString}"/> </Grid> </UserControl> Finally in the App.xaml.cs file we need to set the View and link it to the ViewModel. private void Application_Startup(object sender, StartupEventArgs e) { var myView = new MainPageView(); var myViewModel = new MainPageViewModel(); myView.DataContext = myViewModel; this.RootVisual = myView; }   Once this is done – hey presto – it worked. I typed in some “Test Input” and clicked the generate button and the correct Radio Operators Alphabet was generated. And that’s the end of my first very basic F# Silverlight application.

    I'm using a the WPF DataGrid from the wpf toolkit and a TimePicker from AvalonControlsLibrary to insert a collection of TimeSpans. My problem is that bindings are not working inside the DataGrid, and I have no clue of why this isn't working. Here is my setup: I have the following XAML: <Window x:Class="Views.TestMainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wpf="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:a="http://schemas.AvalonControls/AvalonControlsLibrary/Controls" SizeToContent="WidthAndHeight" MinHeight="250" MinWidth="300"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <GroupBox Grid.Row="0"> <GroupBox.Header> Testing it: </GroupBox.Header> <wpf:DataGrid ItemsSource="{Binding Path=TestSpans}" AutoGenerateColumns="False"> <wpf:DataGrid.Columns> <wpf:DataGridTemplateColumn Header="Start"> <wpf:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <a:TimePicker SelectedTime="{Binding Path=., Mode=TwoWay}" /> </DataTemplate> </wpf:DataGridTemplateColumn.CellEditingTemplate> <wpf:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding}" /> </DataTemplate> </wpf:DataGridTemplateColumn.CellTemplate> </wpf:DataGridTemplateColumn> </wpf:DataGrid.Columns> </wpf:DataGrid> </GroupBox> <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Grid.Row="1"> <a:TimePicker SelectedTime="{Binding Path=SelectedTime, Mode=TwoWay}" /> </StackPanel> </Grid> And this is my ViewModel: Imports System.Collections.ObjectModel Namespace ViewModels Public Class TestMainWindowViewModel Private _selectedTime As TimeSpan = DateTime.Now.TimeOfDay Public Property SelectedTime() As TimeSpan Get Return _selectedTime End Get Set(ByVal value As TimeSpan) _selectedTime = value End Set End Property Private _testSpans As ObservableCollection(Of TimeSpan) = New ObservableCollection(Of TimeSpan) Public Property TestSpans() As ObservableCollection(Of TimeSpan) Get Return _testSpans End Get Set(ByVal value As ObservableCollection(Of TimeSpan)) _testSpans = value End Set End Property Public Sub New() _testSpans.Add(DateTime.Now.TimeOfDay) _testSpans.Add(DateTime.Now.TimeOfDay) _testSpans.Add(DateTime.Now.TimeOfDay) End Sub End Class End Namespace I'm starting this window in application.xaml.vb like this: Class Application ' Application-level events, such as Startup, Exit, and DispatcherUnhandledException ' can be handled in this file. Protected Overrides Sub OnStartup(ByVal e As System.Windows.StartupEventArgs) MyBase.OnStartup(e) Dim window As Views.TestMainWindow = New Views.TestMainWindow window.DataContext = New TestMainWindowViewModel() window.Show() End Sub End Class

  • custom control in DataGridTemplateColumn

    - by Johnsonlu
    Hi all, I'd like to add my custom control into a template column of data grid. The custom control is very similar to a text box, but has an icon in it. The user can click the icon, and selects an item from a prompted window, then the selected item will be filled into the text box. My problem is when the text box is filled, after I click the second column, the text will disappear. If I replace the custom control with a simple text box, the result is the same. Here is the sample code: //Employee.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace SimpleGridTest { public class Employee { public string Department { get; set; } public int ID { get; set; } public string Name { get; set; } } } Mainwindow.xaml <Window x:Class="SimpleGridTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <DataGrid x:Name="grid" Grid.Row="1" Margin="5" AutoGenerateColumns="False" RowHeight="25" RowHeaderWidth="10" ItemsSource="{Binding}" CanUserAddRows="True" CanUserSortColumns="False"> <DataGrid.Columns> <DataGridTemplateColumn Header="Department" Width="150"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBox Text="{Binding Department}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> <DataGridTextColumn Header="ID" Binding="{Binding Path=ID}" Width="100"/> <DataGridTextColumn Header="Name" Binding="{Binding Path=Name}" Width="200"/> </DataGrid.Columns> </DataGrid> </Grid> </Window> MainWindow.xaml.cs using System.Windows; using System.Collections.ObjectModel; namespace SimpleGridTest { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { private ObservableCollection<Employee> _employees = new ObservableCollection<Employee>(); public ObservableCollection<Employee> Employees { get { return _employees; } set { _employees = value; } } public MainWindow() { InitializeComponent(); grid.ItemsSource = Employees; } } } How can I fix this problem? Or I need to write a DataGrid***Column as DataGridTextColumn? Thanks in advance! Best Regards, Johnson

    - by discwiz
    My company is stuck on .Net 3.0. The task I am trying to tackle is simple, I need to bind the IsChecked property of the CheckBoxResolvesCEDAR to the CompletesCEDARWork in my Audio class. The more I read about this it appears that I have to declare CompletesCEDARWork as dependancy propert, but I can not find a good example of how this is done. I found this example, but when I pasted into my code I get an "is not defined" error for GetValue and I have not successfully figure out what MyCode is supposed to represent. Any help/examples would be greatly appreciated. Thanks Public Shared ReadOnly IsSpinningProperty As DependencyProperty = DependencyProperty.Register("IsSpinning", GetType(Boolean), GetType(MyCode)) Public Property IsSpinning() As Boolean Get Return CBool(GetValue(IsSpinningProperty)) End Get Set(ByVal value As Boolean) SetValue(IsSpinningProperty, value) End Set End Property Here is my slimed down Audio Class as it stands now.

  • MVC 3 Nested EditorFor Templates

    - by Gordon Hickley
    I am working with MVC 3, Razor views and EditorFor templates. I have three simple nested models:- public class BillingMatrixViewModel { public ICollection<BillingRateRowViewModel> BillingRateRows { get; set; } public BillingMatrixViewModel() { BillingRateRows = new Collection<BillingRateRowViewModel>(); } } public class BillingRateRowViewModel { public ICollection<BillingRate> BillingRates { get; set; } public BillingRateRowViewModel() { BillingRates = new Collection<BillingRate>(); } } public class BillingRate { public int Id { get; set; } public int Rate { get; set; } } The BillingMatrixViewModel has a view:- @using System.Collections @using WIP_Data_Migration.Models.ViewModels @model WIP_Data_Migration.Models.ViewModels.BillingMatrixViewModel <table class="matrix" id="matrix"> <tbody> <tr> @Html.EditorFor(model => Model.BillingRateRows, "BillingRateRow") </tr> </tbody> </table> The BillingRateRow has an Editor Template called BillingRateRow:- @using System.Collections @model IEnumerable<WIP_Data_Migration.Models.ViewModels.BillingRateRowViewModel> @foreach (var item in Model) { <tr> <td> @item.BillingRates.First().LabourClass.Name </td> @Html.EditorFor(m => item.BillingRates) </tr> } The BillingRate has an Editor Template:- @model WIP_Data_Migration.Models.BillingRate <td> @Html.TextBoxFor(model => model.Rate, new {style = "width: 20px"}) </td> The markup produced for each input is:- <input name="BillingMatrix.BillingRateRows.item.BillingRates[0].Rate" id="BillingMatrix_BillingRateRows_item_BillingRates_0__Rate" style="width: 20px;" type="text" value="0"/> Notice the name and ID attributes the BillingRate indexes are handled nicely but the BillingRateRows has no index instead '.item.'. From my reasearch this is because the context has been pulled out due to the foreach loop, the loop shouldn't be necessary. I want to achieve:- <input name="BillingMatrix.BillingRateRows[0].BillingRates[0].Rate" id="BillingMatrix_BillingRateRows_0_BillingRates_0__Rate" style="width: 20px;" type="text" value="0"/> If I change the BillingRateRow View to:- @model WIP_Data_Migration.Models.ViewModels.BillingRateRowViewModel <tr> @Html.EditorFor(m => Model.BillingRates) </tr> It will throw an InvalidOperationException, 'model item passed into the dictionary is of type System.Collections.ObjectModel.Collection [BillingRateRowViewModel] but this dictionary required a type of BillingRateRowViewModel. Can anyone shed any light on this?

  • TwoWay Binding With ItemsControl

    - by Andrew
    I'm trying to write a user control that has an ItemsControl, the ItemsTemplate of which contains a TextBox that will allow for TwoWay binding. However, I must be making a mistake somewhere in my code, because the binding only appears to work as if Mode=OneWay. This is a pretty simplified excerpt from my project, but it still contains the problem: <UserControl x:Class="ItemsControlTest.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <StackPanel> <ItemsControl ItemsSource="{Binding Path=.}" x:Name="myItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Mode=TwoWay, UpdateSourceTrigger=LostFocus, Path=.}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <Button Click="Button_Click" Content="Click Here To Change Focus From ItemsControl" /> </StackPanel> </Grid> </UserControl> Here's the code behind for the above control: using System; using System.Windows; using System.Windows.Controls; using System.Collections.ObjectModel; namespace ItemsControlTest { /// <summary> /// Interaction logic for UserControl1.xaml /// </summary> public partial class UserControl1 : UserControl { public ObservableCollection<string> MyCollection { get { return (ObservableCollection<string>)GetValue(MyCollectionProperty); } set { SetValue(MyCollectionProperty, value); } } // Using a DependencyProperty as the backing store for MyCollection. This enables animation, styling, binding, etc... public static readonly DependencyProperty MyCollectionProperty = DependencyProperty.Register("MyCollection", typeof(ObservableCollection<string>), typeof(UserControl1), new UIPropertyMetadata(new ObservableCollection<string>())); public UserControl1() { for (int i = 0; i < 6; i++) MyCollection.Add("String " + i.ToString()); InitializeComponent(); myItemsControl.DataContext = this.MyCollection; } private void Button_Click(object sender, RoutedEventArgs e) { // Insert a string after the third element of MyCollection MyCollection.Insert(3, "Inserted Item"); // Display contents of MyCollection in a MessageBox string str = ""; foreach (string s in MyCollection) str += s + Environment.NewLine; MessageBox.Show(str); } } } And finally, here's the xaml for the main window: <Window x:Class="ItemsControlTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:src="clr-namespace:ItemsControlTest" Title="Window1" Height="300" Width="300"> <Grid> <src:UserControl1 /> </Grid> </Window> Well, that's everything. I'm not sure why editing the TextBox.Text properties in the window does not seem to update the source property for the binding in the code behind, namely MyCollection. Clicking on the button pretty much causes the problem to stare me in the face;) Please help me understand where I'm going wrong. Thanx! Andrew

  • How can I read the verbose output from a Cmdlet in C# using Exchange Powershell

    - by mrkeith
    Environment: Exchange 2007 sp3 (2003 sp2 mixed mode) Visual Studio 2008, .Net 3.5 Hello, I'm working with an Exchange powershell move-mailbox cmdlet and have noted when I do so from the Exchange Management shell (using the Verbose switch) there is a ton of real-time information provided. To provide a little context, I'm attempting to create a UI application that moves mailboxes similarly to the Exchange Management Console but desire to support an input file and specific server/database destinations for each entry (and threading). Here's roughly what I have at present but I'm not sure if there is an event I need to register for or what... And to be clear, I desire to get this information in real-time so I may update my UI to reflect what's occurring in the move sequence for the appropriate user (pretty much like the native functionality offered in the Management Console). And in case you are wondering, the reason why I'm not content with the Management Console functionality is, I have an algorithm which I'm using to balance users depending on storage limit, Blackberry use, journaling, exception mailbox size etc which demands user be mapped to specific locations... and I do not desire to create many/several move groups for each common destination or to hunt for lists of users individually through the management console UI. I can not seem to find any good documentation or examples of how to tie into reading the verbose messages that are provided within the console using C# (I see value in being able to read this kind of information in many different scenarios). I've explored the Invoke and InvokeAsync methods and the StateChanged & DataReady events but none of these seem to provide the information (verbose comments) that I'm after. Any direction or examples that can be provided will be very appreciated! A code sample which is little more than how I would ordinarily call any other powershell command follows: // config to use ExMgmt shell, create runspace and open it RunspaceConfiguration rsConfig = RunspaceConfiguration.Create(); PSSnapInException snapInException = null; PSSnapInInfo info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapInException); if (snapInException != null) throw snapInException; Runspace runspace = RunspaceFactory.CreateRunspace(rsConfig); try { runspace.Open(); // create a pipeline and feed script text Pipeline pipeline = runspace.CreatePipeline(); string targetDatabase = @"myServer\myStorageGroup\myDB"; string mbxOwner = "[email protected]"; Command myMoveMailbox = new Command("Move-Mailbox", false, false); myMoveMailbox.Parameters.Add("Identity", mbxOwner); myMoveMailbox.Parameters.Add("TargetDatabase", targetDatabase); myMoveMailbox.Parameters.Add("Verbose"); myMoveMailbox.Parameters.Add("ValidateOnly"); myMoveMailbox.Parameters.Add("Confirm", false); pipeline.Commands.Add(myMoveMailbox); System.Collections.ObjectModel.Collection output = null; // these next few lines that are commented out are where I've tried // registering for events and calling asynchronously but this doesn't // seem to get me anywhere closer // //pipeline.StateChanged += new EventHandler(pipeline_StateChanged); //pipeline.Output.DataReady += new EventHandler(Output_DataReady); //pipeline.InvokeAsync(); //pipeline.Input.Close(); //return; tried these variations that are commented out but none seem to be useful output = pipeline.Invoke(); // Check for errors in the pipeline and throw an exception if necessary if (pipeline.Error != null && pipeline.Error.Count 0) { StringBuilder pipelineError = new StringBuilder(); pipelineError.AppendFormat("Error calling Test() Cmdlet. "); foreach (object item in pipeline.Error.ReadToEnd()) pipelineError.AppendFormat("{0}\n", item.ToString()); throw new Exception(pipelineError.ToString()); } foreach (PSObject psObject in output) { // blah, blah, blah // this is normally where I would read details about a particular PS command // but really pertains to a command once it finishes and has nothing to do with // the verbose messages that I'm after... since this part of the methods pertains // to the after-effects of a command having run, I'm suspecting I need to look to // the asynch invoke method but am not certain or knowing how. } } finally { runspace.Close(); } Thanks!

  • IErrorHandler doesn't seem to be handling my errors in WCF .. any ideas?

    - by John Nicholas
    Have been readign around on IErrorHandler and want to go the config route. so, I have read the following in an attempt to implement it. MSDN Keyvan Nayyeri blog about the type defintion Rory Primrose Blog I have got it to compile and from the various errors i have fixed it seems like WCF is actually loading the error handler. My problem is that the exception that i am throwing to handle in the error handler doesn;t get the exception passed to it. My service implementation simply calls a method on another class that throws ArgumentOutOfRangeException - however this exception never gets handled by the handler.
