如何将TreeViewItem的VirtualizationMode默认值设为Recycling？

我需要将VirtualizingPanel.VirtualizationMode的默认值设置为Recycling，重点作用于TreeViewItem，但尝试了以下方法均未生效，通过XAML实时属性浏览器查看，该属性并未被正确应用。

尝试过的XAML代码 #

<TreeView VirtualizingPanel.IsVirtualizing="True"
          VirtualizingPanel.CacheLengthUnit="Pixel"
          VirtualizingPanel.VirtualizationMode="Recycling"/>

<Style TargetType="{x:Type TreeViewItem}" BasedOn="{StaticResource {x:Type TreeViewItem}}">
    <Setter Property="VirtualizingPanel.VirtualizationMode" Value="Recycling" />
</Style>

尝试过的C#代码 #

static MainWindow()
{
    VirtualizingPanel.VirtualizationModeProperty.OverrideMetadata(
        typeof(VirtualizingPanel), new FrameworkPropertyMetadata(VirtualizationMode.Recycling));
    VirtualizingPanel.VirtualizationModeProperty.OverrideMetadata(
        typeof(MainWindow), new FrameworkPropertyMetadata(VirtualizationMode.Recycling));
    VirtualizingPanel.VirtualizationModeProperty.OverrideMetadata(
        typeof(TreeViewItem), new FrameworkPropertyMetadata(VirtualizationMode.Recycling));
    VirtualizingPanel.VirtualizationModeProperty.OverrideMetadata(
        typeof(VirtualizingStackPanel), new FrameworkPropertyMetadata(VirtualizationMode.Recycling));
}

复现步骤 #

• 下载对应源码并在Visual Studio调试模式启动程序；
• 打开“实时可视化树”窗口，找到TreeViewItem节点下的VirtualizingStackPanel；
• 右键点击该VirtualizingStackPanel选择“属性”，查看VirtualizationMode的属性值。
