Simulares the effect of clicking on the menu drop-down for this button.
If ButtonType is RebarButtonType.Menu or RebarButtonType.MenuOrPush, the MenuClick event is raised and, depending on whether the Handled property of the RebarButtonEventArgs sent to the event handler returns true, the default context menu for the current menu is displayed. For more information about this process, refer to the MenuClick event. For all other values of ButtonType, calling this method has no effect.
