wpf - 在 WPF 中滑动面板的最佳方法是什么？

Question

我有一个相当简单的用户控件(请原谅我的 Xaml，我只是在学习 WPF)，我想将其滑出屏幕。为此，我正在对平移变换进行动画处理(我还尝试使面板成为 Canvas 的子项并以相同的结果为 X 位置设置动画)，但即使在相当快的新计算机上，面板移动也非常不稳定。滑入和滑出的最佳方法是什么(最好使用 KeySplines，以便它可以惯性移动)而不会出现抖动。我的面板上只有8个按钮，所以我认为这不会有太大问题。

这是我正在使用的 Xaml，它在 Kaxaml 中运行良好，但它非常生涩和缓慢(以及在 WPF 应用程序中编译运行时生涩和缓慢)。

到目前为止，看起来最好的解决方案是使用 Visual Brush 并在滑入和滑出面板时移动两个静态图像。此博客文章中描述了与此类似的内容:

Using animated navigation pages in a WPF application (切换到网络存档，但这是从 2008 年开始的，所以不能保证它是否仍然是最好的技术)。
