Fixed header in a gridview (both horizontally and vertically)

Question

Hi,
How to get a fixed header both horizontally and vertically in a gridview?
 
I have my gridview located in a scrollable (auto) panel control and want to have the header row fixed. I want it always visible and when I scroll horizontally I want that the header row should follow so that I can see headers for columns all the time.
 
I have just found solutions for making the header row fixed vertically but I need it to be fixed both vertically and horizontally. Any ideas/solutions is highly appreciated.
