Oh, OK. As you can imagine, the datagrid in ASP.NET is different from the one in Winforms.
In that case, one of the experts on using the datagrid in ASP.NET is Dino Esposito.
If you search on his name on MSDN, Wintellect, WinNetMag (or just do a web search in general), you should be able to find references to articles he's written. He also had an excellent book on ADO.NET/ASP.NET solutions. (I can't remember the exact title).
