Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can use this property to switch between complete menu sets at run time. For example, you can define one MainMenu to be displayed when your multiple-document interface (MDI) form has no active MDI child forms and another MainMenu to display when a child window is displayed. You can also use a different MainMenu when specific conditions exist in your application that require displaying a different menu set.
