When the user clicks the RadOfficeNavigationBarOverflowItem ("...") to open the menu, the items in the RadContextMenuDropDown are always rebuilt.
RadOfficeNavigationBar offers the ContextMenuDropDown property giving direct access to the RadContextMenuDropDown with items. The ContextMenuDropDown's DropDownOpening, DropDownOpened, DropDownClosing and DropDownClosed events are suitable for handling all aspects of opening and closing the menu drop down. Once the menu is opened, the ContextMenuDropDown.Items collection is populated with the correct items and they can be further customized according to the specific requirements.
