When the number of the
RadNavigationBarItem elements exceeds the count of the maximum visible items, they are placed in the overflow menu. To review the overflow menu, click on the navigation options button.
The items in the overflow menu do not support drag and drop operations.
You can control the order of the overflow menu items at runtime through the UI via the navigation options dialog. In addition, you can simulate these actions from code using the commands exposed by the OfficeNavigationBarDialogViewModel property.
