사용자 지정 UserControl의 배경색을 비활성 상태로 변경합니까?

Question

내 응용 프로그램에 대한 사용자 지정 UserControl을 만들었습니다. 컨트롤을 사용할 수없는 경우 배경색을 설정하고 싶습니다. <Style.Trigger>을 사용하는 여러 스레드를 보았지만 작동하지 않습니다. 사람이 사전에 :) 감사 나를 도울 수 있다면

좋을 텐데 :

여기 내 컨트롤 중 하나의 나의 근원이다!

Answer 1

다음은 사용자 정의 컨트롤을 사용하거나 사용하지 않도록 설정할 때 배경을 변경하는 데 사용되는 코드입니다.

스타일 (RectangleStyle1) 및 트리거를 사각형에 추가했습니다. 스타일에서 시도한 변경 사항을 무시하므로 선언에서 채우기를 설정하지 않았습니다.

, 사각형은 배경의 목적을 제공하는 경우

<Style x:Key="RectangleStyle1" TargetType="{x:Type Rectangle}"> 
    <Style.Triggers> 
    <Trigger Property="IsEnabled" Value="True"> 
     <Setter Property="Fill" Value="#FF666666" /> 
    </Trigger> 
    <Trigger Property="IsEnabled" Value="False"> 
     <Setter Property="Fill" Value="White" /> 
    </Trigger> 
    </Style.Triggers> 
</Style> 

이

<Rectangle x:Name="rectangle" 
       Margin="0,0,0,0.013" 
       Stroke="Black" 
       StrokeThickness="0" Style="{DynamicResource RectangleStyle1}" /> 

와 사각형 선언을 교체 UserControl.Resources에이 스타일을 추가 사각형을 제거하고 만들 수 Grid (LayoutRoot) 투명하지 않고 채우기 대신 배경을 사용하여 스타일을 지정합니다.
