Using the ContextMenu Class

Context menus are those handy menus that pop up over controls, usually when you right-click them. They're called context menus because they appear over specific controls—that is, in the context of that control, and so can be tailored to that control. They're supported by the ContextMenu class, which has this class hierarchy:

Object
   MarshalByRefObject
      Component
         Menu
            ContextMenu
