    <p>I have a TabControl with templated content as below:</p> <pre><code>&lt;TabControl x:Name="Items" SelectedItem="{Binding ActiveItem}" TabStripPlacement="Left" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1"&gt; &lt;TabControl.ItemContainerStyle&gt; &lt;!--Some style stuff--&gt; &lt;/TabControl.ItemContainerStyle&gt; &lt;TabControl.Template&gt; &lt;ControlTemplate TargetType="{x:Type TabControl}"&gt; &lt;!--Some structure stuff including a tabpanel and contentPresenter--&gt; &lt;/ControlTemplate&gt; &lt;/TabControl.Template&gt; &lt;TabControl.ContentTemplate&gt; &lt;DataTemplate&gt; &lt;Button x:Name="MyButton" Visibility="{Binding x}" /&gt; &lt;/DataTemplate&gt; &lt;/TabControl.ContentTemplate&gt; &lt;/TabControl&gt; </code></pre> <p>The view containing this TabControl uses a ViewModel similar to this:</p> <pre><code>public class MyPageViewModel : ScreenConductorViewModelBase&lt;IMyTab&gt; { public Visibility x = Visibility.Hidden; } </code></pre> <p>I would like the visibility of the button inside the template to pull from my parent(?) ViewModel, however its trying to retrieve x from the items viewModel. </p> <p>This makes sense to me but Im not sure how to specify that this field should come from the parent instead.</p> <p>I've tried a few things but none of them seem to work:</p> <pre><code> {Binding x} {Binding DataContext.x} {Binding RelativeSource={RelativeSource TemplatedParent}, Path=x} </code></pre> <p>Im sure it must be simple to do this but I cant seem to work out the binding syntax</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).
