I saw this post
that describes how to easily give a RadSlider a ToolTip without having to modify the control template (which is REALLY nice given that I'm using themes and don't want to have to modify the same template multiple times). However, that solution only works for horizontal RadSliders. If you set Orientation=Vertical, the ToolTip starts appearing in the upper left corner and for the life of me I can't figure out why.
I had previously modified this code to work with the Q1 release (which had separate thumbs for each orientation), but now that I've upgraded to the Q2 2011 SP1 release with the new RadSlider control template I'm back to square one. Any help would be appreciated.
