WPF ContextMenu：我怎么知道是谁启动的？

[英]WPF ContextMenu: How can I tell who launched it?

原文 2011-04-27 11:00:39 9 1 c#/ wpf

I have a ContextMenu that can be opened from 2 different StackPanel's, how can I tell which panel actually launched the menu?我有一个 ContextMenu 可以从 2 个不同的 StackPanel 打开，我怎么知道哪个面板实际启动了菜单？

Under WinForms I could consult the SourceControl of the ContextMenuStrip to find this information.在 WinForms 下，我可以查阅 ContextMenuStrip 的 SourceControl 来查找此信息。
