Please see this article here on Codeproject that does the job in synchronizing each text box's "standard" edit menu such as Copy, Cut, Paste, Undo, Select All. Of course, the code originally targets the .NET 1.1, but it can be easily recompiled to target the newer frameworks as well.

In the menu click event you can examine this.ActiveControl to see what control currently has input focus.
