WPF - KeyFrame动画不起作用

Question

我的Window.Resources中有一个KeyFrame动画故事板和一个单独的旋转转换。

旋转变换的工作原理是我可以改变角度并查看内容旋转。我知道故事板正在被调用，因为在点击按钮后，我花了几次去获取PropertyPath。

但是现在它什么都不做 - 没有错误，但没有旋转！

任何人都可以帮忙吗？

感谢，

安迪

问题出在Storyboard.Target="{Binding TemplatedParent}"。提供一个名称Viewport2DVisual3D控制：<Viewport2DVisual3D x:Name="vp" .../>，并设置Storyboard.TargetName="vp"，而不是你有什么...
