Yes that is the right solution. It is my mistake not mentioning that the ScrollContentPresenter was substituted by the GridViewScrollViewer recently.
Thanks for posting the solution to the forum ! I am updating your Telerik points.
In addition I want to share some good news. We are already working on adding this as a feature of RadGridView. We are aiming at internal support of panning , zooming and some kinetic scrolling.
