As mentioned above I looked into subclassing DataRow and DataCell – the oveerriding the PaintForeground/Background events – as a way to speed up the grid.
Got some good hints on how to do this from http://forums.xceed.com/CS/forums/2/892/ShowThread.aspx (Thanks Tommy) with the actual subclassing code fround at http://www.xceedsoft.com/cs/download/XceedGrid/CSharp/Custom Row Cell Derivation.zip (Thanks Andre).
But the upshot – these changes did not noticable speed up the scrolling – so I am still looking for a solution to this problem
