As in a title, does anyone know how to freeze GridView header in ASP.NET ?
I too faced a similar issue while developing in the web applications in Asp.Net 2.0 / 3.5.
One fine day, I came across IdeaSparks ASP.NET CoolControls. It helps to display fix column headers, footer and pager.
I used them personally and I really loved it!
To check the control click here : IdeaSparks ASP.NET CoolControls
Hope this helps!
