When the ribbon is collapsed you can click on a tab and it will drop down. How is the ribbon placed in this state? I am trying to place an element over top of the ribbon and no matter what I try it always seems to be on top. I tried using a popup with no luck. Is there any way I can achieve this?
When the RadRibbonView control is minimized (read more about this feature) the content of its tabs is displayed in a Popup control. This is why the content is visualized over any other controls.
In order display any controls over the content of the RadRibbonTab you can use another Popup control. You can set Popup.IsOpen property to True in the handler of the Loaded event of the MainPage. Furthermore you can subscribe to the MinimizedPopupOpenStateChanged event of the RadRibbonView control and close and open the Popup control based on the minimized state of the ribbon.
For your convenience I implemented this approach in the attached project. Please take a look at it and let me know if it works for you.
