WPF TreeViewItem 선택 해제 된 항목이 여전히 가볍게 강조 표시되었습니다.

Question

각 확장기 컨트롤 내에 ViewTree 컨트롤이있는 확장기 컨트롤이 여러 개 있습니다. 한 ViewTree에서 ViewTreeItem을 선택한 다음 다른 ViewTree에서 다른 ViewTreeItem을 선택하면 새로 선택된 ViewTreeItem이 진한 파란색으로 강조 표시되지만 마지막으로 선택한 항목은 이제 매우 밝은 음영으로 강조 표시됩니다. 제가 무슨 말을하고 있는지 보려면 www.zunjaa.com/public/images/screen.jpg를보십시오. 더 이상 사용하지 않는 항목이 밝은 파란색을 나타내지 않도록하려면 어떻게해야합니까?

감사합니다.

이는 TreeViewItem의 기본 템플릿의 트리거로 인해 발생 : 기본 에어로 테마 템플릿이 제거

<MultiTrigger> 
    <MultiTrigger.Conditions> 
     <Condition Property="IsSelected" Value="true"/> 
     <Condition Property="IsSelectionActive" Value="false"/> 
    </MultiTrigger.Conditions> 
    <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/> 
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/> 
</MultiTrigger>

이 도움을 주셔서 감사합니다. 이것은 내가 함께 결국 무엇이며 나를 위해 작동 :

<Window.Resources> 
<Style TargetType="TreeViewItem"> 
    <Style.Resources> 
    <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" /> 
    </Style.Resources> 
    <Style.Triggers> 
    <MultiTrigger> 
     <MultiTrigger.Conditions> 
     <Condition Property="IsSelected" Value="true"/> 
     <Condition Property="IsSelectionActive" Value="false"/> 
     </MultiTrigger.Conditions> 
     <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/> 
    </MultiTrigger> 
    </Style.Triggers> 
</Style> 
</Window.Resources>
