Silverlight 如何更改故事板中的路径颜色？

这是我为“X”按钮关闭选项卡制作的完整样式。 它起作用了。但我对它不满意

如果您查看

情节提要

s，您会注意到我将两个不同的

路径

s可见性混洗，以实现我的“X”改变颜色的效果。我更愿意进行颜色转换，但似乎无法绑定到

Path的
Stroke
属性

另外，我有
TextBlock
，这样我的光标就可以在整个方块上触发
MouseOver
状态。如果我刚刚离开
路径
-
鼠标上方
将仅在实际的
路径
s颜色上触发。有没有办法让那部分更专业

您必须向下钻取笔刷级别以更改笔划颜色。下面是一个简化的动画，演示了如何使用

<Storyboard x:Name="Storyboard1">
<ColorAnimationUsingKeyFrames 
         Storyboard.TargetProperty="(Shape.Stroke).(SolidColorBrush.Color)" 
         Storyboard.TargetName="path">
     <EasingColorKeyFrame KeyTime="0" Value="Black"/>
            <EasingColorKeyFrame KeyTime="0:0:2.9" Value="Yellow"/>
       </ColorAnimationUsingKeyFrames>
    </Storyboard>
