How to make GridView selectable in asp.net?

[sskaje]

I know we can use \[code\]select command\[/code\] in \[code\]gridview\[/code\] to fire \[code\]selected index change\[/code\] event. But I dont wanna add any button in my griview. I just want that a user can click on a row and it should fire the \[code\]selected index change\[/code\] event.Is there any way to achieve this task?
