UIElement.ClipToBounds在WPF中,但不是Silverlight。如何在Silverlight中进行模拟?

我自己找到了解决办法。像这样重写ArrangeOverride方法。。。

protected override Size ArrangeOverride(Size finalSize)
{
    RectangleGeometry clipRectGeometry = new RectangleGeometry();
    clipRectGeometry.Rect = new Rect(new Point(0,0), finalSize);
    Clip = clipRectGeometry;

    return base.ArrangeOverride();
}
