I am iterating through a grid to find out which rows have a checbox clicked (checkboxes are in column 1). They are all defaulted to clicked initially and I can unclick as many as i like. So for example if i unclick 2 out of eleven rows and hit the save button ,I am told that 10 rows are to be updated instead of 9. The last row unclicked is not recognised. Is there any way to update all the grid changes before hitting the save button.? Hope that makes sense.
