  1. POStyle TreeView but keep it Virtualized
    text
    copied!<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>
