我无法设置更新与 Ellipse 。



如果我看到类似

I cannot set where do you update the properties related to the position of Ellipse.

I would agree that you do if I saw something like

myCanvas.SetLeft(MyEllipse, displacementX);
myCanvas.SetTop(MyEllipse, displacementY);

现在关于动画。我无法看到你在哪里设置 UIElement Canvas 的位置。你可以使用 TranslateTransform ，这是一种正确的方法，但你不应该期望你的任何依赖属性 UIElement 已更新。这些只是不同的事情。

Now about the animation. I cannot see where you animate the position of a UIElement of Canvas. You do it to the TranslateTransform, which is a right approach, but you should not expect that any dependency property of you UIElement are updated. These are just different things.
