page load is called on the render and the postback. so when the button click
happens, your page load code is overwriting the postback value. use the
handy IsPostback property to control logic in the page load.

if you turn viewstate off, then you must load the grid manually (as a copy
is not saved in viewstate), but it must be done in the OnInit event so that
the generated controls exists to get their postbackdata events.
