    copied!<p>I'm trying to do some WPF databinding, but I'm a little hung up at the moment. I have two listboxes and an XML file. The first listbox successfully binds to the XML source. However, when I try to bind to a child of the selected item from first listbox as the source for the second list box, nothing appears. The goal being something like an index or look-up (selecting one index results in finding the related items). Am I missing something here for the databinding? XAML and XML below.</p> <p>XAML:</p> <pre><code>&lt;Window x:Class="MyTool.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="600" Width="800"&gt; &lt;Window.Resources&gt; &lt;XmlDataProvider x:Key="AllDeployments" XPath="Deployments" Source="Deployments.xml" /&gt; &lt;DataTemplate x:Key="dtDeployments"&gt; &lt;StackPanel FlowDirection="LeftToRight" Orientation="Horizontal"&gt; &lt;TextBlock Text="{Binding XPath=@Name}" /&gt; &lt;TextBlock Text=" - "/&gt; &lt;TextBlock Text="{Binding XPath=@Date}" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;DataTemplate x:Key="dtFiles"&gt; &lt;TextBlock Text="{Binding XPath=File}" /&gt; &lt;/DataTemplate&gt; &lt;/Window.Resources&gt; &lt;Grid Name="gMain"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition /&gt; &lt;ColumnDefinition Width="2"/&gt; &lt;ColumnDefinition /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Menu Grid.Column="0" Grid.ColumnSpan="3"&gt;&lt;/Menu&gt; &lt;ListBox Grid.Column="0" Name="lbDeployment" ItemsSource="{Binding Source={StaticResource AllDeployments}, XPath=Deployment}" ItemTemplate="{StaticResource dtDeployments}"&gt;&lt;/ListBox&gt; &lt;GridSplitter Grid.Column="1"&gt;&lt;/GridSplitter&gt; &lt;StackPanel Grid.Column="2"&gt; &lt;ListBox Name="lbFiles" ItemsSource="{Binding Mode=TwoWay, ElementName=lbDeployments, Path=SelectedItem.InnerText, UpdateSourceTrigger=PropertyChanged}" ItemTemplate="{StaticResource dtFiles}" Height="400"&gt;&lt;/ListBox&gt; &lt;/StackPanel&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>XML:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;Deployments MostRecentDate="12/31/2009 8:41:13 PM"&gt; &lt;Filters&gt; &lt;Filter&gt;.cs&lt;/Filter&gt; &lt;Filter&gt;.csproj&lt;/Filter&gt; &lt;/Filters&gt; &lt;Deployment Name="First Deployment" ID="1" Date="6/29/2009 8:41:13 PM"&gt; &lt;File&gt;file1.cs&lt;/File&gt; &lt;File&gt;file2.cs&lt;/File&gt; &lt;/Deployment&gt; &lt;Deployment Name="First Deployment" ID="1" Date="6/29/2009 8:41:13 PM"&gt; &lt;File&gt;file1.cs&lt;/File&gt; &lt;File&gt;file2.cs&lt;/File&gt; &lt;/Deployment&gt; &lt;Deployment Name="First Deployment" ID="1" Date="6/29/2009 8:41:13 PM"&gt; &lt;File&gt;file1.cs&lt;/File&gt; &lt;File&gt;file2.cs&lt;/File&gt; &lt;/Deployment&gt; &lt;Deployment Name="First Deployment" ID="1" Date="6/29/2009 8:41:13 PM"&gt; &lt;File&gt;file1.cs&lt;/File&gt; &lt;File&gt;file2.cs&lt;/File&gt; &lt;/Deployment&gt; &lt;Deployment Name="First Deployment" ID="1" Date="6/29/2009 8:41:13 PM"&gt; &lt;File&gt;file1.cs&lt;/File&gt; &lt;File&gt;file2.cs&lt;/File&gt; &lt;/Deployment&gt; &lt;/Deployments&gt; </code></pre>
