• Handling null values and missing object properties in Silverlight 4

  - by PeterTweed

  Before Silverlight 4 to bind a data object to the UI and display a message associated with either a null value or if the binding path was wrong, you would need to write a Converter.  In Silverlight 4 we find the addition of the markup extensions TargetNullValue and FallbackValue that allows us to display a value when a null value is found in the bound to property and display a value when the property being bound to is not found. This post will show you how to use both markup extensions. Steps: 1. Create a new Silverlight 4 application 2. In the body of the MainPage.xaml.cs file replace the MainPage class with the following code:     public partial class MainPage : UserControl     {         public MainPage()         {             InitializeComponent();             this.Loaded += new RoutedEventHandler(MainPage_Loaded);         }           void MainPage_Loaded(object sender, RoutedEventArgs e)         {             person p = new person() { NameValue = "Peter Tweed" };             this.DataContext = p;         }     }       public class person     {         public string NameValue { get; set; }         public string TitleValue { get; set; }     } This code defines a class called person with two properties.  A new instance of the class is created, only defining the value for one of the properties and bound to the DataContext of the page. 3.  In the MainPage.xaml file copy the following XAML into the LayoutRoot grid:         <Grid.RowDefinitions>             <RowDefinition Height="60*" />             <RowDefinition Height="28*" />             <RowDefinition Height="28*" />             <RowDefinition Height="30*" />             <RowDefinition Height="154*" />         </Grid.RowDefinitions>         <Grid.ColumnDefinitions>             <ColumnDefinition Width="86*" />             <ColumnDefinition Width="314*" />         </Grid.ColumnDefinitions>         <TextBlock Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock1" Text="Name Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock2" Text="Title Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock3" Text="Non Existant Value:" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Name="textBlock4" Text="{Binding NameValue, TargetNullValue='No Name!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Name="textBlock5" Text="{Binding TitleValue, TargetNullValue='No Title!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock6" Text="{Binding AgeValue, FallbackValue='No such property!'}" VerticalAlignment="Top" />    This XAML defines three textblocks – two of which use the TargetNull and one that uses the FallbackValue markup extensions.  4. Run the application and see the person name displayed as defined for the person object, the expected string displayed for the TargetNullValue when no value exists for the boudn property and the expected string displayed for the FallbackValue when the property bound to is not found on the bound object. It's that easy!

• Programmatically disclosing a node in af:tree and af:treeTable

  - by Frank Nimphius

  A common developer requirement when working with af:tree or af:treeTable components is to programmatically disclose (expand) a specific node in the tree. If the node to disclose is not a top level node, like a location in a LocationsView -> DepartmentsView -> EmployeesView hierarchy, you need to also disclose the node's parent node hierarchy for application users to see the fully expanded tree node structure. Working on ADF Code Corner sample #101, I wrote the following code lines that show a generic option for disclosing a tree node starting from a handle to the node to disclose. The use case in ADF Coder Corner sample #101 is a drag and drop operation from a table component to a tree to relocate employees to a new department. The tree node that receives the drop is a department node contained in a location. In theory the location could be part of a country and so on to indicate the depth the tree may have. Based on this structure, the code below provides a generic solution to parse the current node parent nodes and its child nodes. The drop event provided a rowKey for the tree node that received the drop. Like in af:table, the tree row key is not of type oracle.jbo.domain.Key but an implementation of java.util.List that contains the row keys. The JUCtrlHierBinding class in the ADF Binding layer that represents the ADF tree binding at runtime provides a method named findNodeByKeyPath that allows you to get a handle to the JUCtrlHierNodeBinding instance that represents a tree node in the binding layer. CollectionModel model = (CollectionModel) your_af_tree_reference.getValue(); JUCtrlHierBinding treeBinding = (JUCtrlHierBinding ) model.getWrappedData(); JUCtrlHierNodeBinding treeDropNode = treeBinding.findNodeByKeyPath(dropRowKey); To disclose the tree node, you need to create a RowKeySet, which you do using the RowKeySetImpl class. Because the RowKeySet replaces any existing row key set in the tree, all other nodes are automatically closed. RowKeySetImpl rksImpl = new RowKeySetImpl(); //the first key to add is the node that received the drop //operation (departments).            rksImpl.add(dropRowKey);    Similar, from the tree binding, the root node can be obtained. The root node is the end of all parent node iteration and therefore important. JUCtrlHierNodeBinding rootNode = treeBinding.getRootNodeBinding(); The following code obtains a reference to the hierarchy of parent nodes until the root node is found. JUCtrlHierNodeBinding dropNodeParent = treeDropNode.getParent(); //walk up the tree to expand all parent nodes while(dropNodeParent != null && dropNodeParent != rootNode){    //add the node's keyPath (remember its a List) to the row key set    rksImpl.add(dropNodeParent.getKeyPath());      dropNodeParent = dropNodeParent.getParent(); } Next, you disclose the drop node immediate child nodes as otherwise all you see is the department node. Its not quite exactly "dinner for one", but the procedure is very similar to the one handling the parent node keys ArrayList<JUCtrlHierNodeBinding> childList = (ArrayList<JUCtrlHierNodeBinding>) treeDropNode.getChildren();                     for(JUCtrlHierNodeBinding nb : childList){   rksImpl.add(nb.getKeyPath()); } Next, the row key set is defined as the disclosed row keys on the tree so when you refresh (PPR) the tree, the new disclosed state shows tree.setDisclosedRowKeys(rksImpl); AdfFacesContext.getCurrentInstance().addPartialTarget(tree.getParent()); The refresh in my use case is on the tree parent component (a layout container), which usually shows the best effect for refreshing the tree component.

• Has this server been compromised?

  - by Griffo

  A friend is running a VPS (CentOS) His business partner was the sysadmin but has left him high and dry to look after the system. So, I've been asked to help out in fixing an apparent spam problem. His IP address got blacklisted for unsolicited mail. I'm not sure where to look for a problem, but I started with netstat to see what open connections were running. It looks to me like he has remote hosts connected to his SMTP server. Here's the output: Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10029 ESTABLISHED tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10010 ESTABLISHED tcp 0 1 78.153.208.195:35563 news.avanport.pt:smtp SYN_SENT tcp 0 0 78.153.208.195:35559 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 0 0 78.153.208.195:35560 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11647 CLOSING tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11645 CLOSING tcp 0 0 78.153.208.195:35562 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:35561 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:imap 86-41-8-64-dynamic.b-:49446 ESTABLISHED Does this indicate that his server may be acting as an open relay? Mail should only be outgoing from localhost. Apologies for my lack of knowledge but I don't work on linux in my day job. EDIT: Here's some output from /var/log/maillog which looks like it may be the result of spam. If it appears to be the case to others, where should I look next to investigate a root cause? I put the server IP through www.checkor.com and it came back clean.

• Formatting made easy - Silverlight 4

  - by PeterTweed

  One of the simplest tasks in business apps is displaying different types of data to be read in the format that the user expects them.  In Silverlight versions until Silverlight 4 this has meant using a Converter to format data during binding.  This involves writing code for the formatting of the data to bind, instead of simply defining the formatting to use for the data in question where you bind the data to the control.   In Silverlight 4 we find the addition of the StringFormat markup extension that allows us to do exactly this.  Of course the nice thing is the ability to use the common formatting conventions available in C# through the String.Format function.   This post will show you how to use three of the common formatting conventions - currency, a defined number of decimal places for a number and a date format.   Steps:   1. Create a new Silverlight 4 application   2. In the body of the MainPage.xaml.cs file replace the MainPage class with the following code:       public partial class MainPage : UserControl     {         public MainPage()         {             InitializeComponent();             this.Loaded += new RoutedEventHandler(MainPage_Loaded);         }           void MainPage_Loaded(object sender, RoutedEventArgs e)         {             info i = new info() { PriceValue = new Decimal(9.2567), DoubleValue = 1.2345678, DateValue = DateTime.Now };             this.DataContext = i;         }     }         public class info     {         public decimal PriceValue { get; set; }         public double DoubleValue { get; set; }         public DateTime DateValue { get; set; }     }   This code defines a class called info with different data types for the three properties.  A new instance of the class is created and bound to the DataContext of the page.   3.  In the MainPage.xaml file copy the following XAML into the LayoutRoot grid:           <Grid.RowDefinitions>             <RowDefinition Height="60*" />             <RowDefinition Height="28*" />             <RowDefinition Height="28*" />             <RowDefinition Height="30*" />             <RowDefinition Height="154*" />         </Grid.RowDefinitions>         <Grid.ColumnDefinitions>             <ColumnDefinition Width="86*" />             <ColumnDefinition Width="314*" />         </Grid.ColumnDefinitions>         <TextBlock Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock1" Text="Price Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock2" Text="Decimal Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock3" Text="Date Value:" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Name="textBlock4" Text="{Binding PriceValue, StringFormat='C'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock5" Text="{Binding DoubleValue, StringFormat='N3'}" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock6" Text="{Binding DateValue, StringFormat='yyyy MMM dd'}" VerticalAlignment="Top" />   This XAML defines three textblocks that use the StringFormat markup extension.  The three examples use the C for currency, N3 for a number with 3 decimal places and yyy MM dd for a date that displays year 3 letter month and 2 number date.   4. Run the application and see the data displayed with the correct formatting. It's that easy!

• JNI 'problmatic frame' causes JVM to crash

  - by HJED

  Hi I'm using JNI to access the exiv2 library (written in C++) in Java and I'm getting a weird runtime error in the JNI code. I've tried using various -Xms and -Xmx options, but that seems to have no affect. I've also tried running this code on JDK1.7.0 with the same result. # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007ff31807757f, pid=4041, tid=140682078746368 # # JRE version: 6.0_20-b20 # Java VM: OpenJDK 64-Bit Server VM (19.0-b09 mixed mode linux-amd64 ) # Derivative: IcedTea6 1.9.2 # Distribution: Ubuntu 10.10, package 6b20-1.9.2-0ubuntu2 # Problematic frame: # V [libjvm.so+0x42757f] # # If you would like to submit a bug report, please include # instructions how to reproduce the bug and visit: # https://bugs.launchpad.net/ubuntu/+source/openjdk-6/ # --------------- T H R E A D --------------- Current thread (0x000000000190d000): JavaThread "main" [_thread_in_Java, id=4043, stack(0x00007ff319447000,0x00007ff319548000)] siginfo:si_signo=SIGSEGV: si_errno=0, si_code=1 (SEGV_MAPERR), si_addr=0x0000000000000024 Registers: ...

• Using MVVM, how to pass SelectedItems of a XamDataGrid as parameter to the Command raised by the Co

  - by saddaypally

  Hi, I'm trying to pass the item on XamDataGrid on which I do a mouse right click to open a ContextMenu, which raises a Command in my ViewModel. Somehow the method that the Command calls is not reachable in debug mode. This is the snipped from the view <ig:XamDataGrid DataSource="{Binding DrdResults}" Height="700" Width="600"> <ig:XamDataGrid.ContextMenu> <ContextMenu DataContext="{Binding RelativeSource={RelativeSource Mode=Self}, Path=PlacementTarget.DataContext}" AllowDrop="True" Name="cmAudit"> <MenuItem Header="View History" Command="{Binding ViewTradeHistory}" CommandParameter="{Binding Path=SelectedItems}"> </MenuItem> </ContextMenu> </ig:XamDataGrid.ContextMenu> <ig:XamDataGrid.FieldSettings> <ig:FieldSettings AllowFixing="NearOrFar" AllowEdit="False" Width="auto" Height="auto" /> </ig:XamDataGrid.FieldSettings> </ig:XamDataGrid> My code in the corresponding ViewModel for this View is as follows public WPF.ICommand ViewTradeHistory { get { if (_viewTradeHistory == null) { _viewTradeHistory = new DelegateCommand( (object SelectedItems) = { this.OpenTradeHistory(SelectedItems); }); } return _viewTradeHistory; } } And lastly the actual method that gets called by the Command is as below private void OpenTradeHistory(object records) { DataPresenterBase.SelectedItemHolder auditRecords = (DataPresenterBase.SelectedItemHolder)records; // Do something with the auditRecords now. } I'm not sure what am I doing incorrectly here. Any help will be very much appreciated. Thanks, Shravan

• [WPF] Custom TabItem in TabControl

  - by Simon

  I've created CustomTabItem which inherits from TabItem and i'd like to use it while binding ObservableCollection in TabControl <TabControl ItemsSource="{Binding MyObservableCollection}"/> It should like this in XAML, but i do not know how change default type of the output item created by TabControl while binding. I've tried to create converter, but it has to do something like this inside convertin method: List<CustomTabItem> resultList = new List<CustomTabItem>(); And iterate through my input ObservableCollection, create my CustomTab based on item from collection and add it to resultList... I'd like to avoid it, bacause while creating CustomTabItem i'm creating complex View and it takes a while, so i don't want to create it always when something change in binded collection. My class extends typical TabItem and i'd like to use this class in TabControl instead of TabItem. <TabControl.ItemContainerStyle> <Style TargetType="{x:Type local:CustomTabItem}"> <Setter Property="MyProperty" Value="{Binding xxx}"/> </Style> </TabControl.ItemContainerStyle> Code above generates error that Style cannot be applied to TabItem. My main purpose is to use in XAML my own CustomTabItem and bind properties... Just like above... I've also tried to use <TabControl.ItemTemplate/> <TabControl.ContentTemaplte/> But they are just styles for TabItem, so i'll still be missing my properties wchich i added in my custom class.

• WPF DataGrid ComboBox Column: Propagating Header Combobox throughout column...

  - by LostKaleb

  Hey there! Here's my question: I've got a Datagrid in WPF and I have a first column that is a DataGridComboBoxColumn. What I'd like to do is to have a header for that column also with a combobox: altering the header with propagate throughout the column. I can get this done visually, but when I submit the data, the list that is bound with the Datagrid does not carry the new combobox values. <dg:DataGridComboBoxColumn SelectedItemBinding="{Binding BIBStatus}" ItemsSource="{Binding Source={StaticResource typeStatus}}" Width="0.20*"> <dg:DataGridComboBoxColumn.HeaderTemplate> <DataTemplate> <StackPanel> <TextBlock Text="Built-In Bridge"/> <ComboBox SelectedItem="{Binding BIBStatus}" SelectionChanged="ComboBox_SelectionChanged" ItemsSource="{Binding Source={StaticResource typeStatus}}"/> </StackPanel> </DataTemplate> </dg:DataGridComboBoxColumn.HeaderTemplate> </dg:DataGridComboBoxColumn> In the ComboBox_SelectionChanged I have the following code: DataGridColumn comboCol = this.gridResults.Columns[0]; for (int i = 0; i < this.gridResults.Items.Count; i++) { ComboBox myCmBox = (comboCol.GetCellContent(this.gridResults.Items[i]) as ComboBox); myCmBox.SelectedValue = ((ComboBox)sender).SelectedValue; } When I submit the data, I submit the list that is DataContext to the Datagrid; if I change the value of the first column addressing a row at a time, i.e. clicking the cell with the combobox in each row, the values are propagated to the list in DataContext, however if I change the value of the first column by the header it does not. Can anyone tell me what I'm missing? I'm guessing it's the way I affect each row, but I've tried SelectedValue, SelectedItem and SelectedIndex... all to no avail. Thanks in advance...

• Strange Behaviour WPF TreeView ItemContainerStyle and ItemTemplate

  - by Matze

  I just noticed some strange behaviour of WPF's TreeView. I added both ItemContainerStyle to bind to "IsSelected" of my ViewModel and an ItemsTemplated for custom display of my data. But now the user cannot change the selected node anymore. For testing purposes I created a similar UI using ListView and Expander. This version works as excepted. Any tips why TreeView does fail? <TreeView ItemsSource="{Binding ElementName=frame, Path=list}"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}" > <Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}"/> </Style> </TreeView.ItemContainerStyle> <TreeView.ItemTemplate> <HierarchicalDataTemplate> <TreeViewItem Header="{Binding}"> <TextBlock Text="{Binding Path= Item.SomeData}"/> </TreeViewItem> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView>

• WPF ListView SelectedItem is null

  - by ozczecho

  Hi All I have a Listview that has a checkbox as one of the columns. If I click anywhere but the actual checkbox the SelectedItem of the ListView is set to the current selected row, as expected. If, on the other hand I click onto the checkbox (without clicking on the row first) then the SelectedItem is null or the previously clicked row. Can anyone help me out.... Cheers <ListView Width="auto" SelectionMode="Single" x:Name="listBox" ItemsSource="{Binding MyData}" SelectedItem="{Binding Path=SelectedMyData}"> <ListView.View> <GridView> <GridViewColumn Header="Date" Width="120"> <GridViewColumn.CellTemplate> <DataTemplate> <ContentPresenter Style="{StaticResource DateTimeContent}" Content="{Binding MyDate}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <CheckBox IsThreeState="False" Checked="OnChkChecked" Unchecked="OnChkChecked" IsChecked="{Binding IsCorrect}"></CheckBox> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView>

• wpf treeview ObjectDataProvider update - how?

  - by wonea

  I've been having trouble updating the data bindings which relates to a treeview. The dataset is mapped onto the ObjectDataProvider, passed through two data templates. Now I've tried updating the ObjectDataProvider with two calls, hoping that they would trigger the CreateTheDataSet() method, and rebuild the tree. Tried calling; thetreeView.ItemTemplate.LoadContent(); thetreeView.Items.Refresh(); Program code; <Window.Resources> <ObjectDataProvider x:Key="dataSetProvider" MethodName="CreateDataSet" ObjectType="{x:Type local:DataSetCreator}" /> <DataTemplate x:Key="DetailTemplate"> <TextBlock Text="{Binding Path=personname}" /> </DataTemplate> <HierarchicalDataTemplate x:Key="MasterTemplate" ItemsSource="{Binding Master2Detail}" ItemTemplate="{StaticResource DetailTemplate}"> <TextBlock Text="{Binding Path=jobname}" /> </HierarchicalDataTemplate> </Window.Resources> <x:Name="thetreeView" DataContext="{StaticResource dataSetProvider}" ItemsSource="{Binding compMaster}" ItemTemplate="{StaticResource MasterTemplate}" /> My dataset creation class; public static class DataSetCreator { public static DataSet CreateTheDataSet() { DataSet dataset = new DataSet(); // Create dataset ... blah blah return dataset; } }

• WPF Ignoring ProgressBar Style

  - by Nidonocu

  Following a problem in WPF 4 where the default ProgressBar template has an off-white highlight applied causing it to dull the foreground colour, I decided to extract the template and manually edit the values to white. After doing this, I put the template as a style in App.xaml for global use and the Visual Studio designer began to use it right away. However, when I run my app, the default style is still being applied: I then tried setting the style specifically using a key, then even having it as an inline style and finally as a inline template without a wrapping style for the specific progress bar and it is still ignored. What's going wrong? Current Code for progress bar: <ProgressBar Grid.Column="1" Grid.Row="2" Height="15" Width="355" Margin="0,0,0,7" IsIndeterminate="{Binding ProgressState, FallbackValue=False}" Visibility="{Binding ProgressVisibility, FallbackValue=Collapsed}" Value="{Binding ProgressValue, Mode=OneWay, FallbackValue=100}" Foreground="{Binding ProgressColor,FallbackValue=Red}"> <ProgressBar.Template> <ControlTemplate> <Grid Name="TemplateRoot" SnapsToDevicePixels="True"> <Rectangle RadiusX="2" RadiusY="2" Fill="{TemplateBinding Panel.Background}" /> ...

• C# WCF Server retrieves 'List<T>' with 1 entry, but client doesn't receive it?! Please help Urgentl

  - by Neville

  Hi Everyone, I've been battling and trying to research this issue for over 2 days now with absolutely no luck. I am trying to retrieve a list of clients from the server (server using fluentNHibernate). The client object is as follow: [DataContract] //[KnownType(typeof(System.Collections.Generic.List<ContactPerson>))] //[KnownType(typeof(System.Collections.Generic.List<Address>))] //[KnownType(typeof(System.Collections.Generic.List<BatchRequest>))] //[KnownType(typeof(System.Collections.Generic.List<Discount>))] [KnownType(typeof(EClientType))] [KnownType(typeof(EComType))] public class Client { #region Properties [DataMember] public virtual int ClientID { get; set; } [DataMember] public virtual EClientType ClientType { get; set; } [DataMember] public virtual string RegisterID {get; set;} [DataMember] public virtual string HerdCode { get; set; } [DataMember] public virtual string CompanyName { get; set; } [DataMember] public virtual bool InvoicePerBatch { get; set; } [DataMember] public virtual EComType ResultsComType { get; set; } [DataMember] public virtual EComType InvoiceComType { get; set; } //[DataMember] //public virtual IList<ContactPerson> Contacts { get; set; } //[DataMember] //public virtual IList<Address> Addresses { get; set; } //[DataMember] //public virtual IList<BatchRequest> Batches { get; set; } //[DataMember] //public virtual IList<Discount> Discounts { get; set; } #endregion #region Overrides public override bool Equals(object obj) { var other = obj as Client; if (other == null) return false; return other.GetHashCode() == this.GetHashCode(); } public override int GetHashCode() { return ClientID.GetHashCode() | ClientType.GetHashCode() | RegisterID.GetHashCode() | HerdCode.GetHashCode() | CompanyName.GetHashCode() | InvoicePerBatch.GetHashCode() | ResultsComType.GetHashCode() | InvoiceComType.GetHashCode();// | Contacts.GetHashCode() | //Addresses.GetHashCode() | Batches.GetHashCode() | Discounts.GetHashCode(); } #endregion } As you can see, I have allready tried to remove the sub-lists, though even with this simplified version of the client I still run into the propblem. my fluent mapping is: public class ClientMap : ClassMap<Client> { public ClientMap() { Table("Clients"); Id(p => p.ClientID); Map(p => p.ClientType).CustomType<EClientType>(); ; Map(p => p.RegisterID); Map(p => p.HerdCode); Map(p => p.CompanyName); Map(p => p.InvoicePerBatch); Map(p => p.ResultsComType).CustomType<EComType>(); Map(p => p.InvoiceComType).CustomType<EComType>(); //HasMany<ContactPerson>(p => p.Contacts) // .KeyColumns.Add("ContactPersonID") // .Inverse() // .Cascade.All(); //HasMany<Address>(p => p.Addresses) // .KeyColumns.Add("AddressID") // .Inverse() // .Cascade.All(); //HasMany<BatchRequest>(p => p.Batches) // .KeyColumns.Add("BatchID") // .Inverse() // .Cascade.All(); //HasMany<Discount>(p => p.Discounts) // .KeyColumns.Add("DiscountID") // .Inverse() // .Cascade.All(); } The client method, seen below, connects to the server. The server retrieves the list, and everything looks right in the object, still, when it returns, the client doesn't receive anything (it receive a List object, but with nothing in it. Herewith the calling method: public List<s.Client> GetClientList() { try { s.DataServiceClient svcClient = new s.DataServiceClient(); svcClient.Open(); List<s.Client> clients = new List<s.Client>(); clients = svcClient.GetClientList().ToList<s.Client>(); svcClient.Close(); //when receiving focus from server, the clients object has a count of 0 return clients; } catch (Exception e) { MessageBox.Show(e.Message); } return null; } and the server method: public IList<Client> GetClientList() { var clients = new List<Client>(); try { using (var session = SessionHelper.OpenSession()) { clients = session.Linq<Client>().Where(p => p.ClientID > 0).ToList<Client>(); } } catch (Exception e) { EventLog.WriteEntry("eCOWS.Data", e.Message); } return clients; //returns a list with 1 client in it } the server method interface is: [UseNetDataContractSerializer] [OperationContract] IList<Client> GetClientList(); for final references, here is my client app.config entries: <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_IDataService" listenBacklog="10" maxConnections="10" transferMode="Buffered" transactionProtocol="OleTransactions" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00"> <readerQuotas maxDepth="51200000" maxStringContentLength="51200000" maxArrayLength="51200000" maxBytesPerRead="51200000" maxNameTableCharCount="51200000" /> <security mode="Transport"/> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:9000/eCOWS/DataService" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IDataService" contract="eCowsDataService.IDataService" name="NetTcpBinding_IDataService" behaviorConfiguration="eCowsEndpointBehavior"> </endpoint> <endpoint address="MEX" binding="mexHttpBinding" contract="IMetadataExchange" /> </client> <behaviors> <endpointBehaviors> <behavior name="eCowsEndpointBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> and my server app.config: <system.serviceModel> <bindings> <netTcpBinding> <binding name="netTcpBinding" maxConnections="10" listenBacklog="10" transferMode="Buffered" transactionProtocol="OleTransactions" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" sendTimeout="00:10:00" receiveTimeout="00:10:00"> <readerQuotas maxDepth="51200000" maxStringContentLength="51200000" maxArrayLength="51200000" maxBytesPerRead="51200000" maxNameTableCharCount="51200000" /> <security mode="Transport"/> </binding> </netTcpBinding> </bindings> <services> <service name="eCows.Data.Services.DataService" behaviorConfiguration="eCowsServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:9001/eCOWS/" /> <add baseAddress="net.tcp://localhost:9000/eCOWS/" /> </baseAddresses> </host> <endpoint address="DataService" binding="netTcpBinding" contract="eCows.Data.Services.IDataService" behaviorConfiguration="eCowsEndpointBehaviour"> </endpoint> <endpoint address="MEX" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="eCowsEndpointBehaviour"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="eCowsServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceThrottling maxConcurrentCalls="10" maxConcurrentSessions="10"/> <serviceDebug includeExceptionDetailInFaults="False" /> </behavior> <behavior name="MexBehaviour"> <serviceMetadata /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> I use to run into "socket closed / network or timeout" errors, and the trace showed clearly that on the callback it was looking for a listening endpoint, but couldn't find one. Anyway, after adding the UseNetSerializer that error went away, yet now I'm just not getting anything. Oh PS. if I add all the commented out List items, I still retrieve an entry from the DB, but also still not receive anything on the client. if I remove the [UseNetDataContractSerializer] I get the following error(s) in the svclog : WARNING: Description Faulted System.ServiceModel.Channels.ServerSessionPreambleConnectionReader+ServerFramingDuplexSessionChannel WARNING: Description Faulted System.ServiceModel.Channels.ServiceChannel ERROR: Initializing[eCows.Data.Models.Client#3]-failed to lazily initialize a collection of role: eCows.Data.Models.Client.Addresses, no session or session was closed ... ERROR: Could not find default endpoint element that references contract 'ILogbookManager' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. If I add a .Not.LazyLoad to the List mapping items, I'm back at not receiving errors, but also not receiving any client information.. Sigh! Please, if anyone can help with this I'd be extremely grateful. I'm probably just missing something small.. but... what is it :) hehe. Thanks in advance! Neville

• WCF Web Service Gives 404 error in Azure

  I'm new to using WCF and Azure, but I have a WCF Web Service that works correctly when debugging in Visual Studio. I set the startup project to Azure, and I get 404 errors for any URL I try related to the service. Here is what I think is relavant code: From IWebService.cs [OperationContract] [WebGet(UriTemplate = "GetData/Xml?value={value}", ResponseFormat=WebMessageFormat.Xml)] string GetDataXml(string value); and from Web.config: <system.serviceModel> <services> <service name="WebService" behaviorConfiguration="WebServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="WebEndpointBehavior"></endpoint> <endpoint address="ws" binding="wsHttpBinding" contract="IWebService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WebServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> I have tried changing the binding to 'basicHttpBinding', but that had no luck. Thanks in advance for any help!

• TextBox, Button and ListBox in a ListBox

  - by Emil C

  I have a listbox with a bunch of contols in each list item. <ListBox x:Name="projectList" IsSynchronizedWithCurrentItem="True"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}" /> <ListBox x:Name="taskList" ItemsSource="{Binding Tasks}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <TextBox x:Name="textBoxTask" /> <Button x:Name="ButtonAddNewTask" Content="Test" CommandParameter="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=DataContext}" Click="ButtonAddNewTask_Click" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> When I click on the button in the listbox i want to add a new item to the listbox within the listbox. I've come this far. So my question is how do I get hold of the textbox and how do I update the listbox? Here is my click event private void ButtonAddNewTask_Click(object sender, RoutedEventArgs e) { Button button = (Button)sender; Project proj = button.DataContext as Project; if(proj.Tasks == null) proj.Tasks = new List<Task>(); proj.Tasks.Add(new Task("Added Task")); } Thanx

• Problems with WCF reliable session (reliable messaging)

  - by Rob

  Hi, In our WCF application I am trying to configure reliable sessions. Service: <wsHttpBinding> <binding name="BindingStabiHTTP" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152" messageEncoding="Text"> <reliableSession enabled="true" ordered="true" inactivityTimeout="00:10:00"/> <readerQuotas maxDepth="0" maxStringContentLength="0" maxArrayLength="0" maxBytesPerRead="0" maxNameTableCharCount="0" /> </binding> </wsHttpBinding> Client: <wsHttpBinding> <binding name="BindingClientWsHttpStandard" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="true" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> Unfortunately I get an error which is as follows: No signature message parts were specified for messages with the 'http://schemas.xmlsoap.org/ws/2005/02/rm/CreateSequence' action. If I disable the reliableSession on the client I get this message: The action is not supported by this endpoint. Only WS-ReliableMessaging February 2005 messages are processed by this endpoint. So it seems that the server is configured correctly for RM. I cannot find anything valuable about the error I get so I don't know how to fix this. Any ideas what can be wrong? Thank in advance, Rob

• ListView + MultipleSelect + MVVM = ?

  - by Dave

  If I were to say "the heck with it!", I could just give my ListView with SelectionMode="Multiple" a name, and be able to get all of the selected items very easily. But I'm trying to stick to MVVM as much as possible, and I want to somehow databind to an ObservableCollection that holds the value from the Name column for each selected item. How in the world do you do this? Single selection is simple, but the multi selection solution is not obvious to me with my current WPF / MVVM knowledge. I read this question on SO, and while it does give me some good insight, I don't know how to add the necessary binding to a row, because I am using a ListView with a GridView as its View, not a ListBox. Here's what my XAML basically looks like: <ListView DockPanel.Dock="Top" ItemsSource="{Binding ClientPreview}" SelectionMode="Multiple"> <ListView.View> <GridView AllowsColumnReorder="False"> <GridViewColumn Header="Name"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Name}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Address"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Address}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> It sounds like the right thing to do is to databind each row's IsSelected property to each object stored in the ObservableCollection I'm databinding to. I just haven't figured out how to do this.

• Understanding ItemsSource and DataContext in a DataGrid

  - by Ben McCormack

  I'm trying to understand how the ItemsSource and DataContext properties work in a Silverlight Toolkit DataGrid. I'm currently working with dummy data and trying to get the data in the DataGrid to update when the value of a combo box changes. My MainPage.xaml.vb file currently looks like this: Partial Public Class MainPage Inherits UserControl Private IssueSummaryList As List(Of IssueSummary) Public Sub New() GetDummyIssueSummary("Day") InitializeComponent() dgIssueSummary.ItemsSource = IssueSummaryList 'dgIssueSummary.DataContext = IssueSummaryList ' End Sub Private Sub GetDummyIssueSummary(ByVal timeInterval As String) Dim lst As New List(Of IssueSummary)() 'Generate dummy data for lst ' IssueSummaryList = lst End Sub Private Sub ComboBox_SelectionChanged(ByVal sender As System.Object, ByVal e As System.Windows.Controls.SelectionChangedEventArgs) Dim cboBox As ComboBox = CType(sender, ComboBox) Dim cboBoxItem As ComboBoxItem = CType(cboBox.SelectedValue, ComboBoxItem) GetDummyIssueSummary(cboBoxItem.Content.ToString()) End Sub End Class My XAML currently looks this for the DataGrid: <sdk:DataGrid x:Name="dgIssueSummary" AutoGenerateColumns="False" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Binding="{Binding ProblemType}" Header="Problem Type"/> <sdk:DataGridTextColumn Binding="{Binding Count}" Header="Count"/> </sdk:DataGrid.Columns> </sdk:DataGrid> The problem is that if I set the value of the ItemsSource property of the data grid equal to IssueSummaryList, it will display the data when it loads, but it won't update when the underlying IssueSummaryList collection changes. If I set the DataContext of the grid to be IssueSummaryList, no data will be displayed when it renders. I must not understand how ItemsSource and DataContext are supposed to function, because I expect one of those properties to "just work" when I assign a List object to them. What do I need to understand and change in my code so that as data changes in the List, the data in the grid is updated?

• Styling columns based on DataGridTemplateColumn in a WPF DataGrid

  - by nareshbhatia

  I am using a WPF DataGrid where one of the columns has a requirement to show an "Edit" hyperlink if the row is editable - this is indicated by a boolean flag in the backing model for the row. I was able to achieve this using a DataGridTemplateColumn - no problems. However an additional requirement on the entire row is not to show any highlights when the row is selected (this is a blue background by default). I have been able to achieve this on other columns by defining the DataGridCell style with a transparent background, e.g. <DataGridTextColumn Header="Id" Binding="{Binding Path=Id}" HeaderStyle="{StaticResource DataGridColumnHeaderStyle}" CellStyle="{StaticResource DataGridCellStyle}" /> where DataGridCellStyle is defined as follows: <Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}"> <Setter Property="Background" Value="Transparent" /> ... </Style> However the column in question, a DataGridTemplateColumn, does not offer a "CellStyle" attribute which I can use for turning off selection highlights. So my question is how to set the cell style when using a DataGridTemplateColumn? Here's my implementation of the column which satisfies the first requirement (i.e. showing an "Edit" hyperlink if the row is editable): <DataGridTemplateColumn Header="Actions" HeaderStyle="{StaticResource CenterAlignedColumnHeaderStyle}"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Visibility="{Binding Path=Editable, Converter={StaticResource convVisibility}}" Style="{StaticResource CenterAlignedElementStyle}"> <Hyperlink Command="..." CommandParameter="{Binding}"> <TextBlock Text="Edit" /> </Hyperlink> </TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> Thanks.

• Bind to a method in WPF?

  - by Cameron MacFarland

  How do you bind to an objects method in this scenario in WPF? public class RootObject { public string Name { get; } public ObservableCollection<ChildObject> GetChildren() {...} } public class ChildObject { public string Name { get; } } XAML: <TreeView ItemsSource="some list of RootObjects"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type data:RootObject}" ItemsSource="???"> <TextBlock Text="{Binding Path=Name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type data:ChildObject}"> <TextBlock Text="{Binding Path=Name}" /> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView> Here I want to bind to the GetChildren method on each RootObject of the tree. EDIT Binding to an ObjectDataProvider doesn't seem to work because I'm binding to a list of items, and the ObjectDataProvider needs either a static method, or it creates it's own instance and uses that. For example, using Matt's answer I get: System.Windows.Data Error: 33 : ObjectDataProvider cannot create object; Type='RootObject'; Error='Wrong parameters for constructor.' System.Windows.Data Error: 34 : ObjectDataProvider: Failure trying to invoke method on type; Method='GetChildren'; Type='RootObject'; Error='The specified member cannot be invoked on target.' TargetException:'System.Reflection.TargetException: Non-static method requires a target.

• Building error in Eclipse with build.xml

  - by Zachary

  I am working on a Java project with Eclipse. This project requires a second project (not mine), named sams in its build-path. The sams is provided with a build.xml file and it should generate some code using Apache CXF when building it. When I use Apache ANT on Eclipse and run the cxf.generated command from its build file I get the following error: Buildfile: C:\Docs\ZacRocha\Desktop\sams\build.xml cxf.generated: [echo] Generating code using Apache CXF wsdl2java...

• ASP.NET MVC OutputCache with POST Controller Actions

  - by Maxim Z.

  I'm fairly new to using the OutputCache attribute in ASP.NET MVC. Static Pages I've enabled it on static pages on my site with code such as the following: [OutputCache(Duration = 7200, VaryByParam = "None")] public class HomeController : Controller { public ActionResult Index() { //... If I understand correctly, I made the whole controller cache for 7200 seconds (2 hours). Dynamic Pages However, how does it work with dynamic pages? By dynamic, I mean where the user has to submit a form. As an example, I have a page with an email form. Here's what that code looks like: public class ContactController : Controller { // // GET: /Contact/ public ActionResult Index() { return RedirectToAction("SubmitEmail"); } public ActionResult SubmitEmail() { //In view for CAPTCHA: <%= Html.GenerateCaptcha() %> return View(); } [CaptchaValidator] [AcceptVerbs(HttpVerbs.Post)] public ActionResult SubmitEmail(FormCollection formValues, bool captchaValid) { //Validate form fields, send email if everything's good... if (isError) { return View(); } else { return RedirectToAction("Index", "Home"); } } public void SendEmail(string title, string name, string email, string message) { //Send an email... } } What would happen if I applied OutputCache to the whole controller here? Would the HTTP POST form submission work? Also, my form has a CAPTCHA; would that change anything in the equation? In other words, what's the best way to approach caching with dynamic pages? Thanks in advance.

• Trigger for ComboBox in Silverlight

  - by Budda

  Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: 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:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"
