To disable a menu item at design time
With the menu item selected on the form, set the Enabled property to false.
Disabling the first or top-level menu item in a menu disables all the menu items contained within the menu. Likewise, disabling a menu item that has submenu items disables the submenu items. If all the commands on a given menu are unavailable to the user, it is considered good programming practice to both hide and disable the entire menu, as this presents a clean user interface. You should both hide and disable the menu, as hiding alone does not prevent access to a menu command via a shortcut key. Set theproperty of a top-level menu item to false to hide the entire menu.
