radPanorama1.PanoramaElement.GroupLayout.Orientation = Orientation.Vertical;
But it doesn't seem to bring up a vertical scroll bar or pretty much do anything from what I can tell. The horizontal scrollbar is still there. I tried another way like:
radPanorama1.PanoramaElement.ScrollBar.ScrollType = ScrollType.Vertical;
This way seems to just completely collapse or hides the tiles I had in my panorama, but when I move over them with my cursor, the tiles appear visible again, but I still don't see any vertical scrollbar.
