我在 TreeView 中使用 HierarchicalDataTemplate，并且还想覆盖 TreeViewItem 的默认模板，以便在选择某个项目时，它仅突出显示文本，而不包括其旁边的图标。

<TreeView.ItemTemplate>
     <HierarchicalDataTemplate ItemsSource="{Binding Children}">
                        <TreeViewItem Style="{StaticResource TreeViewItemStyle}" Header="{Binding DisplayText}" />

      </HierarchicalDataTemplate>
</TreeView.ItemTemplate>


            <TreeView.Resources>
                <Style x:Key="TreeViewItemFocusVisual">
                    <Setter Property="Control.Template">
                        <Setter.Value>
                            <ControlTemplate>
                                <Rectangle/>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
                <Style x:Key="ExpandCollapseToggleStyle" TargetType="{x:Type ToggleButton}">
                    <Setter Property="Focusable" Value="False"/>
                    <Setter Property="Width" Value="19"/>
                    <Setter Property="Height" Value="13"/>
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type ToggleButton}">
                                <Border Width="19" Height="13" Background="Transparent">
                                    <Border Width="9" Height="9" SnapsToDevicePixels="true" BorderBrush="#FF7898B5" BorderThickness="1" CornerRadius="1">

                                                <GradientStop Color="White" Offset=".2"/>
                                                <GradientStop Color="#FFC0B7A6" Offset="1"/>
                                            </LinearGradientBrush>
                                        </Border.Background>
