Don't store the row index of checkbox in gridview. You have to bind the Datakey of GridView as a unique of the values retrived from the database. Then save that unique value for checkboxes instead of 1,3,6.





When you bind the GridView at page load run a for loop for each row of GridView and change the checkbox state by matching the datakey of each row.
