    <p>For my treeview I have two different classes that provide the ItemsSource.</p> <pre><code>public class TreeViewModel : ViewModelBase { public ObservableCollection&lt;NodeViewModel&gt; Items { get; set; } } public class NodeViewModel : ViewModelBase { public string Id { get; set; } public string Name { get; set; } public ObservableCollection&lt;NodeViewModel&gt; Children { get; set; } } </code></pre> <p>Now I want my TreeView to display the Items in TreeViewModel and show hierarchical data as provided by the NodeViewModel.</p> <p>Here is my XAML</p> <pre><code>&lt;Window x:Class="TreeViewMasterDetails.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TreeViewMasterDetails" Title="MainWindow" Height="350" Width="525"&gt; &lt;Grid&gt; &lt;TreeView Height="Auto" HorizontalAlignment="Stretch" Margin="10" VerticalAlignment="Stretch" Width="Auto"&gt; &lt;TreeView.Resources&gt; &lt;HierarchicalDataTemplate DataType="x:Type local:TreeViewModel" ItemsSource="{Binding Items}"&gt; &lt;TextBlock Text="{Binding Path=Name}"&gt;&lt;/TextBlock&gt; &lt;/HierarchicalDataTemplate&gt; &lt;HierarchicalDataTemplate DataType="x:Type local:NodeViewModel" ItemsSource="{Binding Children}"&gt; &lt;TextBlock Text="{Binding Name}"&gt;&lt;/TextBlock&gt; &lt;/HierarchicalDataTemplate&gt; &lt;/TreeView.Resources&gt; &lt;/TreeView&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>Have tried to provide <code>Items</code> as the <code>ItemsSource</code> of the <code>TreeView</code>. It does not show the data hierarchically, if displaying anything.</p> <p>And I tried using the <code>ItemTemplate</code> instead of the <code>TreeView.Resources</code>, too.</p> <p>What is wrong about it?</p> <p>Perhaps a problem is the first <code>TextBlock Text Binding</code>? I want to display the <code>Name</code> property of the <code>NodeViewModel</code> in <code>Items</code> there.</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).
