treeviewitem 배경색 변경을 비활성화하는 방법은 무엇입니까?

Question

다음과 같은 문제점이 있습니다. WPF 앱에 두 개의 treeview 컨트롤이 있고 첫 번째 트리의 항목 중 하나를 클릭 한 다음 두 번째 트리의 항목 중 하나를 클릭하면 첫 번째 트리의 항목이 해당 항목을 변경합니다. 색깔. multitrigger에서 배경색을 변경하려고 시도했지만 효과가없는 템플릿 속성은 배경색을 변경하려고했습니다.

이 동작을 어떻게 비활성화 할 수 있습니까? 여기 내 샘플 창 코드

유일한 것은 당신이 게시 한 코드에서 잘못된 볼 수있다 (임 뒤에 코드에서 트 리뷰 컨트롤을 변경하지 않음)인가하면 Trigger의 Setter 세트 모두 Background입니다 같은 색상 Foreground{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}

또한 어쩌면 명시 적으로 Selector.IsSelectionActive로 MultiTrigger 조건을 설정하려고 수 :

나는 이러한 변화와 함께 게시 된 코드를 시도하는 것은 (-8 Windows에서 나를 위해 잘 작동) :

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

당신 만 Style 설정 상위 TreeViewItem은 TreeViewItemStyle1입니다. 따라서 기본값 Style은 Style을 지정하지 않는 자식 TreeViewItem에 적용됩니다. TreeViewItem의 모든 문자에 자동으로 적용하려면 스타일 키를 선언에서 제거하고 TargetType
