<asp:CommandField with dynamic SelectText or <asp:Hyperlink with server side call

[MasterNone]

Can somebody suggest a way for me to bind the SelectText instead of
static text or show any cool methods to make a server side postback to
the same page instead of navigate.

Either of those solutions are acceptable. I am using a GridView control
and would like to have one fo these soltions.

Thanks in advance.
