    <p>I have this strange problem where I am unable to get an item from a ListBox. I have even tried to use the code from <a href="http://msdn.microsoft.com/en-us/library/system.windows.controls.listbox.aspx" rel="nofollow">this site</a> but it fails in my situation with a message: <em>Unable to cast object of type 'System.Reflection.RuntimePropertyInfo' to type 'System.Windows.Controls.ListBoxItem'.</em> The ListBox is binded to colors from XAML.</p> <pre class="lang-xaml prettyprint-override"><code>xmlns:sys="clr-namespace:System;assembly=mscorlib" &lt;Window.Resources&gt; &lt;ObjectDataProvider MethodName="GetType" ObjectType="{x:Type sys:Type}" x:Key="colorsTypeOdp"&gt; &lt;ObjectDataProvider.MethodParameters&gt; &lt;sys:String&gt;System.Windows.Media.Colors, PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 &lt;/sys:String&gt; &lt;/ObjectDataProvider.MethodParameters&gt; &lt;/ObjectDataProvider&gt; &lt;ObjectDataProvider ObjectInstance="{StaticResource colorsTypeOdp}" MethodName="GetProperties" x:Key="colorPropertiesOdp"&gt; &lt;/ObjectDataProvider&gt; &lt;/Window.Resources&gt; &lt;!-- etc --&gt; &lt;ListBox x:Name="ListBoxColor" ItemsSource="{Binding Source={StaticResource colorPropertiesOdp}}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto" Margin="5" Grid.RowSpan="5" SelectedIndex="113"&gt; &lt;ListBox.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;WrapPanel Orientation="Vertical" /&gt; &lt;/ItemsPanelTemplate&gt; &lt;/ListBox.ItemsPanel&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel Orientation="Horizontal"&gt; &lt;Rectangle Fill="{Binding Name}" Stroke="Black" Margin="2" StrokeThickness="1" Height="20" Width="50"/&gt; &lt;Label Content="{Binding Name}" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; </code></pre> <pre class="lang-vb prettyprint-override"><code>Private Sub ListBoxColor_SelectionChanged(sender As Object, _ e As SelectionChangedEventArgs) Handles ListBoxColor.SelectionChanged Dim lbsender As ListBox Dim li As ListBoxItem lbsender = CType(sender, ListBox) li = CType(lbsender.SelectedItem, ListBoxItem) </code></pre> <p>It breaks on the last line. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
