    <p>I'm working on a GIS website in C# and Silverlight, and I'm trying to populate a ListBox based on map layers. The code works if I lump everything together in a single XAML file (where the Map is defined in the same file), but I am trying to separate things into separate classes, and the ListBox will not populate in the other class.</p> <p>XAML Code..</p> <p> </p> <pre><code> &lt;CheckBox IsChecked="{Binding Visible, Mode=TwoWay}" /&gt; &lt;Slider Margin="-5,0,0,0" Minimum="0" Maximum="1" Width="30" Value="{Binding Opacity, Mode=TwoWay}" Height="18" /&gt;--&gt; &lt;TextBlock Text="{Binding ID, Mode=OneWay}" Margin="5,0,0,0" &gt; &lt;ToolTipService.ToolTip&gt; &lt;StackPanel MaxWidth="400"&gt; &lt;TextBlock FontWeight="Bold" Text="{Binding CopyrightText}" TextWrapping="Wrap" /&gt; &lt;TextBlock Text="{Binding Description}" TextWrapping="Wrap" /&gt; &lt;/StackPanel&gt; &lt;/ToolTipService.ToolTip&gt; &lt;/TextBlock&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; </code></pre> <p> </p> <p>myMap is being set when the class is called by this C# code...</p> <p>public partial class TableOfContents : UserControl { Map myMap;</p> <pre><code>public TableOfContents(ref Map map) { InitializeComponent(); myMap = map; foreach (Layer thisLayer in myMap.Layers) { layerList.Items.Add(new TextBlock() { Text = thisLayer.ID }); } } </code></pre> <p>}</p> <p>The foreach statement adds TextBlocks for all of the map layers (this is just test code), so I know the information is being passed correctly, but the data binding defined in XAML doesn't seem to work.</p> <p>Any thoughts?</p> <p>EDIT: The XAML Code seems to be clipped in the post (although it's visible when I edit it). The data binding is defined by: ItemsSource="{Binding Path=Layers, ElementName=myMap}</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.
