如何确保 WPF UserControl 元素在控件边界之外可见？
我有一个包含网格内交互式元素的用户控件。用户可以移动这些元素并调整其大小，这通常会导致它们超出我的控制范围。当元素确实落在外面时，我不希望它们被夹住。无论如何，我希望它们是可见的。不幸的是，将 ClipToBounds 设置为 FALSE 并没有解决问题。
即使在过去类似的情况下，我也使用过 ClipToBounds，虽然它一开始似乎有效，但我注意到当拖动到某些位置时，越界元素偶尔会消失。对于它们消失的原因似乎没有一个合乎逻辑的解释，除了布局系统可能优先考虑将 ClipToBounds 设置为 false，仅在某些位置。
这非常烦人，我的解决方法涉及以编程方式不断调整 UserControl 的大小以包含所有内部元素，这似乎是一种非常糟糕的方法。有没有一种更干净的方法来确保我的元素在控件边界之外始终可见（最好不使用 ClipToBounds - 是否有我在这里缺少的属性）？非常感谢任何帮助。
I have a UserControl containing interactive elements within a grid. The user can move and resize these elements, often causing them to fall outside the bounds of my control. When elements do fall outside, I don't want them to clip. I want them to be visible no matter what. Unfortunately, setting ClipToBounds to FALSE did not solve the problem.
Even in the past during a similar situation, I had used ClipToBounds, and while it appeared to work at first, I noticed that out-of-bounds elements occasionally disappeared when dragged to certain locations. There didn't seem to be a logical explanation as to why they disappeared except that perhaps the layout system was out-prioritizing ClipToBounds being set to false, only at certain locations.
It was very annoying and my work-around involved programmatically resizing my UserControl constantly to encase all inner elements, which seems to be a very bad approach. Is there a cleaner way to ensure that my elements are always visible outside the bounds of my control (preferably without using ClipToBounds - is there a property I'm missing here)? Any help is greatly appreciated.
