Question

我有一个包含图像和TextBlock的堆栈面板。

TextBlock绑定到一种样式，该样式使其闪烁，其背景颜色从红色变为黑色，反之亦然。

我想将TextBlock backgorund颜色绑定到stackpanel背景颜色，也就是说，当TextBlock背景颜色为Red时，我需要stackpanel背景颜色为Red，而当TextBlock背景颜色为Black时，stackpanel背景颜色必须更改为黑色等等...

在我的代码下面：

<Border Visibility="{Binding Path=BlinkOn, Converter={StaticResource BoolToVis}}" BorderThickness="1" BorderBrush="Red" CornerRadius="5" Margin="5">
  <StackPanel Orientation="Horizontal" Width="auto" Background="Red">
    <Image Width="24" Height="24" Source="/My.Images;component/Warning.png" />                    
    <TextBlock x:Name="lblStoryboard"
               TextAlignment="Center"
               Padding="5"                                                         
               Width="Auto"    
               Background="Red"
               Foreground="Black"
               FontSize="12.5"
               FontWeight="Bold"
               Style="{StaticResource BlinkingTextBlock}"
               Text="Hi there!" 
               TextWrapping="WrapWithOverflow"
               Visibility="{Binding Path=BlinkOn, Converter={StaticResource BoolToVis}}">
    </TextBlock>
 </StackPanel>
</Border>

我已经通过将TextBlock背景属性绑定到stackpanel背景属性来解决：

<Border Visibility="{Binding Path=BlinkOn, Converter={StaticResource BoolToVis}}" BorderThickness="1" BorderBrush="Red" CornerRadius="5" Margin="5">
  <StackPanel Orientation="Horizontal" Width="auto">
    <StackPanel.Background>
        <Binding ElementName="txtStoryboard" Path="Background"/>
    </StackPanel.Background>
    <Image Width="24" Height="24" Source="/My.Images;component/Warning.png" />                    
    <TextBlock x:Name="txtStoryboard"
               TextAlignment="Center"
               Padding="5"                                                         
               Width="Auto"    
               Background="Red"
               Foreground="Black"
               FontSize="12.5"
               FontWeight="Bold"
               Style="{StaticResource BlinkingTextBlock}"
               Text="Hi there!" 
               TextWrapping="WrapWithOverflow"
               Visibility="{Binding Path=BlinkOn, Converter={StaticResource BoolToVis}}">
    </TextBlock>
 </StackPanel>
</Border>

使用与包含的TextBlock背景相同的颜色设置WPF stackpanel背景颜色
