Question

我目前有一个自定义WPF窗口，其中包含自定义标题栏，按钮和边框。我还有一个故事板动画如下：

    <Storyboard x:Key="SlideLeftToRight"  
                TargetProperty="RenderTransform.(TranslateTransform.X)"
                AccelerationRatio=".5"
                DecelerationRatio=".5">
        <DoubleAnimation Storyboard.TargetName="PageViewer" Duration="0:0:0.8" From="{Binding Width, ElementName=PrimaryWindow}" To="0"/>
        <DoubleAnimation Storyboard.TargetName="BorderVisual" Duration="0:0:0.8" From="0" To="-1252"/>
    </Storyboard>

    <Storyboard x:Key="SlideRightToLeft" 
                TargetProperty="RenderTransform.(TranslateTransform.X)"
                AccelerationRatio=".5"
                DecelerationRatio=".5">
        <DoubleAnimation Storyboard.TargetName="PageViewer" Duration="0:0:0.8" From="-1252" To="0"/>
        <DoubleAnimation Storyboard.TargetName="BorderVisual" Duration="0:0:0.8" From="0" To="{Binding Width, ElementName=PrimaryWindow}"/>
    </Storyboard>

唯一的问题是，这些动画显示在窗口边框上，从而覆盖了阴影效果。有没有办法可以使自定义边框看起来不可绘制？这是我的窗口的完整XAML，以防有用。

我解决了这个问题。只需更改动画父对象上的ClipToBounds属性就会停止动画离开父动画。

<Grid ClipToBounds="True">
     ...
</Grid>

停止在Window的自定义边框上绘制对象
