我遇到的问题是我在 Stackpanel 中有一个菜单，它在 ScrollViewer 中。现在即使隐藏了水平滚动条也可以水平滚动。现在的主要问题是，我无法为按钮创建 Clickevent。看来我的滚动事件阻止了它下面的东西。

最佳答案
现在我在 JohnChris 和其他优秀程序员的帮助下找到了我想要的解决方案 :D 感谢所有人 :D
必须添加对项目的引用，UIAutomationProvider.dll 和两个 using 语句，使用 System.Windows.Automation.Peers 和 System.Windows.Automation.Provider，这些允许使用 Invoke Provider 和 Peers
