In your tutorial as you state you use a temporary DataTable to maintain the list selected rows or records and then use the DataTable to bind the secondary GridView. What I'd like to do is;
I'm using the IfUserIsInRole function and when I get the users Identity and name I'm prepopulating the gvSelected GridView with data (only people associated with that user) on page load. When I try to add none prepopulated people from the gvAll GridView to the gvSelected GridView all the origional prepopulated rows from the gvselected GridView are over written.
How can I prevent thios from happening?
