..and what your problem is?

Enable ViewState is probably the easiest.
I would change the grid refresh so it uses Ajax, that way you prevent full postback and maintain all other control states.

Check page properties there are several maintain state (such as scroll position) properties/methods that may help.
Finally, write your own implementation - this is hardest one as you have to maintain session object with current grid state, but you have most control.

You are getting checkbox value from Database then on OnRowDataBound you can bind data.
