You could use the Loaded
event of the RadRibbonBackstage
. The event is raised every time user tries to open Backstage
. You could use flag to set the content only the first time a user opens the Backstage
You can also use the RadRibbonView ApplicationMenuOpenStateChanged
event which will be fired whenever you open or close the BackstageMenu
I hope this information helps.
