如何禁用WPF中的所有自定義樣式

Question

我重寫代碼中某些控件的默認樣式。在此之後，我想要禁用所有兒童（深遞歸）的某些控件的所有自定義樣式。例如XAML：

<StackPanel> 
     <StackPanel.Resources> 
      <Style TargetType="Button"> 
       <Setter Property="Background" Value="Red"/> 
      </Style> 
      <Style TargetType="TextBlock"> 
       <Setter Property="Background" Value="Red"/> 
      </Style> 
     </StackPanel.Resources> 
     <Button>red style here is ok</Button> 
     <TextBlock> also ok</TextBlock> 
     <StackPanel> 
      <StackPanel.Resources> 
       <!-- magic command to disable ALL custom styles, for all controls like 
       <Style TargetType = "FrameworkElement"/> --> 
      </StackPanel.Resources> 
      <Button> no style plz </Button> 
      <TextBlock> bad style-_- </TextBlock> 
     </StackPanel> 
    </StackPanel> 

我知道我可以使用樣式= null，但對我來說它的壞的解決方案，因爲我需要申請這一招對每種類型的控件。我如何解決我的問題？

您可以注入一個空白樣式，該樣式優先於其他樣式。像：

<StackPanel> 
    <StackPanel.Resources> 
     <Style TargetType="Button"> 
      <Setter Property="Background" Value="Red"/> 
     </Style> 
     <Style TargetType="TextBlock"> 
      <Setter Property="Background" Value="Red"/> 
     </Style> 
    </StackPanel.Resources> 
    <Button>red style here is ok</Button> 
    <TextBlock> also ok</TextBlock> 
    <StackPanel> 
     <StackPanel.Resources> 
      <!-- magic command to disable ALL custom styles, for all controls --> 
      <Style TargetType="Button" /> 
      <Style TargetType="TextBlock" /> 
     </StackPanel.Resources> 
     <Button> no style plz </Button> 
     <TextBlock> bad style-_- </TextBlock> 
    </StackPanel> 
</StackPanel>
