When I build my DataGrid, I have a session variable that holds an
ordered list of record numbers that I use elsewhere in the application.
I allow sorting on a few columns, and that works great. But I can't
figure out how to reorder my list of record numbers when the grid is
sorted by last name, processed date, etc. I built a ListChanged event
handler, but it only fired two or three times on the sort with a type
of Reset, and old and new indexes were always -1. Does anyone know
where I can find the reordered list? Something has to know what the new
order is, because it displays correctly on the screen.

Thanks,
Mike
