Windows Forms General. Sign in to vote. I would like to be able to add menu separator items to a ComboBox control. I'm guessing I'm going to have to create a derived class and override the OnPaint method. Any suggestions on the best way to draw it?

Shortcut keys are widely used to access menu items. For Example. So by pressing the function key F1 we can access the menu Item function. Make the text property of menu item a dash - to make that menu item a separator bar. In the following program I also included the Event handlers to all the menu items. The following program shows how to create a menu with the enhancements,.
Replacing, Cloning, Merging of Menus At times, when creating Windows Forms applications, we require generating a copy of a menu that already created. In such circumstances, rather than recreating complete menu structures when you want to duplicate a given menu's functionality, we can use the CloneMenu method.
Likewise it is useful to have the items from two menus appear in a single menu, such as merging a Multiple Document Interface MDI container's menu with that of its active MDI child. Similarly in some situations depending on the run-time requirements of the application we have to Add, Delete the menus or Enabling, disabling of the menu items. Now let us see all those things in details with an example. The menu also includes a View menu and Edit menu.
If we click the Merge Edit-View menu item then it creates a new top-level menu named "Merged" by merging the edit menu and view menu.
