    <p>You are applying the "treeViewItemStyle" only to the first level of items in the TreeView. You have to set it as well as the ItemContainerStyle of the TreeViewItems. So, in your ControlTemplate, you'll need something like:</p> <pre><code>&lt;ControlTemplate TargetType="TreeViewItem"&gt; &lt;TreeViewItem ItemContainerStyle="{StaticResource treeViewItemStyle}".../&gt; &lt;/ControlTemplate&gt; </code></pre> <p>Better yet, you can just remove the "x:Key" attribute in your Style declaration. Doing so will automatically apply the style to <strong>all</strong> TreeViewItems.</p> <p><em>SIDE NOTE:</em></p> <p>I would suggest that instead of overriding the ControlTemplate like what you did above, just use property Setters in the Style instead. Something like:</p> <pre><code>&lt;Style TargetType="TreeViewItem"&gt; &lt;Setter Property="IsExpanded" Value="{Binding Path=IsExpanded, Mode=TwoWay}"/&gt; &lt;Setter Property="ItemsSource" Value="{Binding Path=SubCategories}"/&gt; &lt;Setter Property="ItemTemplate" Value="{StaticResource menuHierarchicalTemplate}"/&gt; &lt;Setter Property="Header"&gt; &lt;Setter.Value&gt; &lt;StackPanel Orientation="Horizontal" &gt; &lt;TextBlock Height="24" FontSize="12" Padding="5" Text="{Binding Path=Name}" /&gt; &lt;/StackPanel&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>It's quite unusual to use the same Control as part of the ControlTemplate of itself (i.e. using TreeViewItem in the ControlTemplate of a TreeViewItem).</p>

    1. COThanks for your great response. Unfortunately, the XAML parser won't let me apply the same style recursively to many ItemContainerStyle attributes. Your idea of just using setters was good, but because of issues with selecting items I have to use the template I already have. It seems the only way I can get around all of this is to create the same TreeViewItem style many times each with different names in order to expand a deeper hierarchy. This is bad as it will artificially limit the depth to which I can expand each TreeViewItem node. Do you have any other suggestions?

    2. COWhen I use your side note approach, I always get an exception that states, "Specified element is already the logical child of another element. Disconnect it first".

    3. COre: exception. you're probably getting it because you're setting the TreeViewItem.Header property on both the style and the HierarchicalDataTemplate. Try to remove one of them and see if it works.

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.
