    <p>I have a custom control that is derived from <code>TabItem</code>, and I want to databind that custom <code>TabItem</code> to a stock <code>TabControl</code>. I would rather avoid creating a new <code>TabControl</code> just for this rare case.</p> <p>This is what I have and I'm not having any luck getting the correct control to be loaded. In this case I want to use my <code>ClosableTabItem</code> control instead of the stock <code>TabItem</code> control.</p> <pre><code>&lt;TabControl x:Name="tabCases" IsSynchronizedWithCurrentItem="True" Controls:ClosableTabItem.TabClose="TabClosed" &gt; &lt;TabControl.ItemTemplate&gt; &lt;DataTemplate DataType="{x:Type Controls:ClosableTabItem}" &gt; &lt;TextBlock Text="{Binding Path=Id}" /&gt; &lt;/DataTemplate&gt; &lt;/TabControl.ItemTemplate&gt; &lt;TabControl.ContentTemplate&gt; &lt;DataTemplate DataType="{x:Type Entities:Case}"&gt; &lt;CallLog:CaseReadOnlyDisplay DataContext="{Binding}" /&gt; &lt;/DataTemplate&gt; &lt;/TabControl.ContentTemplate&gt; &lt;/TabControl&gt; </code></pre> <p><strong>EDIT:</strong> This is what I ended up with, rather than trying to bind a custom control. The "<a href="https://stackoverflow.com/questions/935043/how-can-i-get-a-close-button-on-a-templated-tabitem-in-wpf">CloseCommand</a>" im getting from a <a href="https://stackoverflow.com/questions/935043/how-can-i-get-a-close-button-on-a-templated-tabitem-in-wpf">previous question</a>.</p> <pre><code> &lt;Style TargetType="{x:Type TabItem}" BasedOn="{StaticResource {x:Type TabItem}}" &gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type TabItem}"&gt; &lt;Border Name="Border" Background="LightGray" BorderBrush="Black" BorderThickness="1" CornerRadius="25,0,0,0" SnapsToDevicePixels="True"&gt; &lt;StackPanel Orientation="Horizontal"&gt; &lt;ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="20,1,5,1"/&gt; &lt;Button Command="{Binding Path=CloseCommand}" Cursor="Hand" DockPanel.Dock="Right" Focusable="False" Margin="1,1,5,1" Background="Transparent" BorderThickness="0"&gt; &lt;Image Source="/Russound.Windows;component/Resources/Delete.png" Height="10" /&gt; &lt;/Button&gt; &lt;/StackPanel&gt; &lt;/Border&gt; &lt;ControlTemplate.Triggers&gt; &lt;Trigger Property="IsSelected" Value="True"&gt; &lt;Setter Property="FontWeight" Value="Bold" /&gt; &lt;Setter TargetName="Border" Property="Background" Value="LightBlue" /&gt; &lt;Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" /&gt; &lt;Setter TargetName="Border" Property="BorderBrush" Value="DarkBlue" /&gt; &lt;/Trigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre>

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).
