Did you try to google this question before asking it? This is a very basic question and you can find all kinds of help for it on google. One of the main results that came up when I googled was the MSDN for the GridView class:

MSDN GridView Class[^]

I looked through the methods and found one called Sort:
MSDN GridView.Sort Method[^]

It includes code samples of how to get it to work.
