As in a title, does anyone know how to freeze GridView header in ASP.NET ?
Option (a) buy into a UI package that includes a souped-up GridView with this functionality built-in.
Option (b) roll your own - it's not simple. Dino Esposito has one approach.
EDIT: Just noticed that the Dino article links to a subscriber-only area on the ASPnetPro magazine site.
Here's another approach using extenders.
