    <p>I'm having trouble with my UserControl with following source code:</p> <pre><code>[ContentProperty("SetContent")] public partial class HeaderContainer : UserControl { // Header region public FrameworkElement SetContent { get { return (FrameworkElement)GetValue(SetContentProperty); } set { SetValue(SetContentProperty, value); } } public static readonly DependencyProperty SetContentProperty = DependencyProperty.Register("SetContent", typeof(FrameworkElement), typeof(HeaderContainer), new PropertyMetadata(null)); public HeaderContainer() { InitializeComponent(); DataContext = this; } } </code></pre> <p>This is my XAML </p> <pre><code>&lt;StackPanel&gt; &lt;Border&gt; &lt;TextBlock Text="{Binding Header}" /&gt; &lt;/Border&gt; &lt;ContentPresenter Content="{Binding SetContent}"/&gt; &lt;/StackPanel&gt; </code></pre> <p>And here is my Problem:</p> <pre><code>&lt;c:HeaderContainer Header="List"&gt; &lt;ItemsControl ItemsSource="{Binding ObjectList}" &gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;TextBlock Text="{Binding DisplayName}"/&gt; &lt;TextBlock Text="{Binding SecondLine}" Foreground="Gray" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/c:HeaderContainer&gt; </code></pre> <p>The Itemscontrol itself is working, also the UserControl, when I add content in XAML. The problem is, when I add Items to ObjectList while it's in the HeaderContainer - nothing happens. Where am I thinking wrong?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
