Now i want to delete the selected row? i dont want to delete a record using delete button in the grid. i want when i select a row and press a delete button then the selected row should delete from grid as well from database.

I guess if you have already done the update part then you can easily delete the selected row. Just call a delete function, instead of the update one, and then call the DataBind() function of the GridView.
