    <p>The <strong>Virtualization</strong> on my <strong>TreeView</strong> works when I have only styled the <strong>TreeViewItem</strong> with this bit of xaml in the style:</p> <pre><code>&lt;Style.Triggers&gt; &lt;Trigger Property="VirtualizingStackPanel.IsVirtualizing" Value="true"&gt; &lt;Setter Property="ItemsPanel"&gt; &lt;Setter.Value&gt; &lt;ItemsPanelTemplate&gt; &lt;VirtualizingStackPanel/&gt; &lt;/ItemsPanelTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; </code></pre> <p>But then if I try and give the <strong>TreeView</strong> itself a style with <strong>Style={Resource}</strong> the virtualization breaks, i.e:</p> <pre><code>&lt;Style x:Key="FontTreeViewStyle" TargetType="{x:Type TreeView}"&gt; &lt;Setter Property="OverridesDefaultStyle" Value="True" /&gt; &lt;Setter Property="SnapsToDevicePixels" Value="True" /&gt; &lt;Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto" /&gt; &lt;Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" /&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="TreeView"&gt; &lt;Border Name="Border" CornerRadius="1" BorderThickness="1" BorderBrush="{DynamicResource BorderMediumColor}" Background="{DynamicResource ControlLightColor}"&gt; &lt;ScrollViewer Focusable="False" CanContentScroll="False" Padding="4"&gt;&lt;!-- Style="{StaticResource MyScrollViewer}"--&gt; &lt;ItemsPresenter /&gt; &lt;/ScrollViewer&gt; &lt;/Border&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>Thanks in advance!</p>

    1. COFixed. I copied the style generated in Expression Blend and realised I had not fully implemented VirtualizingStackPanel.IsVirtualizing

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).
