Die Reihenfolge, MenuItemBinding in der Objekte in der Auflistung angezeigt werden, wirkt sich nicht darauf aus, wie diese Objekte auf die Menu Menü Elemente in einem-Steuerelement angewendet werden.The order in which MenuItemBinding objects appear in the collection has no effect on how those objects are applied to the menu items in a Menu control.
