Thanks Nadya, this is exactly the solution that I needed. I had the binding part and the custom method in the grid but I didn't know how to get the name of the header object or column name in the custom method in the grid.

My solution was to use the "member class" to create the header object from
a prg and that works good. But now that you have given me a solution I don't know which one to use now! :). For member class like the fact that I can treat the header object separately but hate the prg and recompiling.

Thanks.
