I suggest you to use LeftColumn property to determine does grids are coordinated or not and how many times DoScroll() method must be called to made LeftColumn in both grids equal, as it can scroll one column per method call only.
This coordination routine must be called from both Scrolled and AfterRowColChange events.

Hope this helps.
