推荐答案

如果您能理解路由事件，那么将能够找出点击来自的确切控制 - 通过这 [ ^ ] 。

If you can understand Routed Events, then will able to figure out the exact control the click is coming from - go through this[^].

这是一种错误的方法。相反，你应该直接处理你想要处理的元素点击并忽略其他元素。



问题只是反OOP和反事件的结果 - 定向思维，应该修复。

This is a wrong approach. Instead, you should directly handle a click on the element you want to handle and ignore others.

The question is just the result of anti-OOP and anti-event-oriented thinking, which should be fixed.
