I am not sure what you need to implement. Basically the RibbonBackstage
control is designed to take up all available space defined by the root window panel or by the BackstageClippingElement
property. So I am not sure what you mean by hide the right side? If you can send us a snapshot illustrating your requirements, that would help us better assist you.
Also, it might be better to take advantage of the ApplicationMenu
control instead of using the Backstage
menu. You can find more information about the RibbonView ApplicationMenu
