WPF：设计 HierarchicalDataTemplate 的样式

这是一个简单的 DataTemplate，

<Grid.Resources>
<HierarchicalDataTemplate ItemsSource="{Binding Items}" DataType="{x:Type entities:Folder}" ItemContainerStyle="{StaticResource FileComponentItem}">
    <Grid ShowGridLines="False" HorizontalAlignment="Center">
        <TextBlock Grid.Column="0" Text="{Binding Type}" />
    </Grid>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate ...... />
</Grid.Resources>

它应用于 TreeView

<TreeView Grid.Row="1" BorderThickness="0" ItemsSource="{Binding}"  ItemContainerStyle="{StaticResource FlattenedTreeViewItem}"></TreeView>

请注意，样式 FileComponentItem 应用于类型实体的模板：Folder

它有效，接受样式仅应用于此节点（文件夹节点）的子节点。这意味着，只有文件夹的子节点才会获得样式（无论在文件夹下展开什么项目，而文件夹本身仍然没有样式）。

我希望能够控制应用模板的项目的样式，而不是子项的样式

Here is a simple DataTemplate

<Grid.Resources>
<HierarchicalDataTemplate ItemsSource="{Binding Items}" DataType="{x:Type entities:Folder}" ItemContainerStyle="{StaticResource FileComponentItem}">
    <Grid ShowGridLines="False" HorizontalAlignment="Center">
        <TextBlock Grid.Column="0" Text="{Binding Type}" />
    </Grid>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate ...... />
</Grid.Resources>

this is applied to TreeView

<TreeView Grid.Row="1" BorderThickness="0" ItemsSource="{Binding}"  ItemContainerStyle="{StaticResource FlattenedTreeViewItem}"></TreeView>

Notice that a style FileComponentItem is applied to a template for type entities:Folder

It works, accept the style is only applied to the children of this node (Folder node).
meaning, only the child nodes of Folder, will get the style (whatever items are expanded under Folder, while Folder itself remains not styled).

I would like to be able to control the style of items to which the template is applied, not the children
