    <p>I'm going to give you a solution using attached properties. Check the code:</p> <p><strong>Attached Properties</strong></p> <pre><code>public static class IndexAttachedProperty { #region TabItemIndex public static int GetTabItemIndex(DependencyObject obj) { return (int) obj.GetValue(TabItemIndexProperty); } public static void SetTabItemIndex(DependencyObject obj, int value) { obj.SetValue(TabItemIndexProperty, value); } // Using a DependencyProperty as the backing store for TabItemIndex. This enables animation, styling, binding, etc... public static readonly DependencyProperty TabItemIndexProperty = DependencyProperty.RegisterAttached("TabItemIndex", typeof (int), typeof (IndexAttachedProperty), new PropertyMetadata(-1)); #endregion #region TrackTabItemIndex public static bool GetTrackTabItemIndex(DependencyObject obj) { return (bool) obj.GetValue(TrackTabItemIndexProperty); } public static void SetTrackTabItemIndex(DependencyObject obj, bool value) { obj.SetValue(TrackTabItemIndexProperty, value); } // Using a DependencyProperty as the backing store for TrackTabItemIndex. This enables animation, styling, binding, etc... public static readonly DependencyProperty TrackTabItemIndexProperty = DependencyProperty.RegisterAttached("TrackTabItemIndex", typeof (bool), typeof (IndexAttachedProperty), new PropertyMetadata(false, TrackTabItemIndexOnPropertyChanged)); private static void TrackTabItemIndexOnPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var tabControl = GetParent(d, p =&gt; p is TabControl) as TabControl; var tabItem = GetParent(d, p =&gt; p is TabItem) as TabItem; if (tabControl == null || tabItem == null) return; if (!(bool)e.NewValue) return; int index = tabControl.Items.IndexOf(tabItem.DataContext == null ? tabItem : tabItem.DataContext); SetTabItemIndex(d, index); } #endregion public static DependencyObject GetParent(DependencyObject item, Func&lt;DependencyObject, bool&gt; condition) { if (item == null) return null; return condition(item) ? item : GetParent(VisualTreeHelper.GetParent(item), condition); } } </code></pre> <p>This code define two attached properties, the first one is to set if an item tracks the the tab item index in wich it is contained. The second one is the index property.</p> <p><strong>XAML Sample code:</strong></p> <pre><code> &lt;TabControl.ItemTemplate&gt; &lt;DataTemplate DataType="{x:Type WpfApplication3:A}"&gt; &lt;StackPanel x:Name="tabItemRoot" WpfApplication3:IndexAttachedProperty.TrackTabItemIndex ="True"&gt; &lt;TextBlock Text="{Binding Text}"/&gt; &lt;TextBlock Text="{Binding Path=(WpfApplication3:IndexAttachedProperty.TabItemIndex), ElementName=tabItemRoot}"/&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/TabControl.ItemTemplate&gt; </code></pre> <p>The above code is an example of using the attached property. You may adapt to your code easy.</p> <p><strong>Result:</strong></p> <p><img src="https://i.stack.imgur.com/ENgsI.png" alt="enter image description here"></p> <p>Hope this code works for you...</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.

SQuiL has stopped working due to an internal error.

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