我有一个看起来像这样的上下文菜单

I have a context menu that looks like this

A |--1 |--2 |--3

我需要访问该上下文菜单从调用的对象，选择1 2或3之后

I need to access the object that the context menu is called from, after selecting 1 2 or 3

的意思，如果这是一个TextBox1中的上下文菜单，然后我需要访问该对象，我该怎么办呢？

meaning if this is a context menu of a textbox1 then I need to access that object, how do I do that?

忘了提，这是一个WPF应用程序。因此，使用IM的System.Windows.Controls的 而文本菜单的编程方式创建

Forgot to mention, this is a WPF application. so Im using the System.Windows.Controls and the ContextMenu is created programmatically

推荐答案

您可以走了树，并从 ContextMenu.PlacementTarget ，如：

You can walk up the tree and get the control from the ContextMenu.PlacementTarget, e.g.

private void MenuItem_Click(object sender, RoutedEventArgs e) { var item = sender as MenuItem; while (item.Parent is MenuItem) { item = (MenuItem)item.Parent; } var menu = item.Parent as ContextMenu; if (menu != null) { var droidsYouAreLookingFor = menu.PlacementTarget as TextBox; //... } }
