I have a simple question, I have the following menu.

Main Menu
Sub Menu 1
Sub menu 2
Sub menu 3
Sub sub menu 3.1
Sub sub menu 3.2
Sub sub menu 3.3

I would like to direct if the Form load that "Sub sub menu 3.3" is selected.

Is that possible?
If so, how?

The menu item should have a PerformClick method that you can call in the form's load event handler.

When the form loads, you want to execute what the "Sub sub menu 3.3" doing? is that what you want? or just highlight the "Sub sub menu 3.3"?
