Sub-Menus

MenuItem objects in Windows Forms have their own MenuItem collections. This allows you to create a hierarchical structure of menus that have their own cascading child menus within them. The following listing illustrates this process.

  MenuItem filemenu = new MenuItem();
  filemenu.Text = "&File";
  menu.MenuItems.Add(filemenu);

    MenuItem open = new MenuItem();
    open.Text = "&Open";
    filemenu.MenuItems.Add(open);

    MenuItem print= new MenuItem();
    print.Text = "Print...";
    filemenu.MenuItems.Add(print);

      MenuItem temp= new MenuItem();
      temp.Text = "Pre&view";
      print.MenuItems.Add(temp);

      temp= new MenuItem();
      temp.Text = "To &File";
      print.MenuItems.Add(temp);

    MenuItem exit= new MenuItem();
    exit.Text = "E&xit";
    filemenu.MenuItems.Add(exit);

As before, the indentation shows the menu level. Figure 3.1.10 shows the menu in action.
