I display a list in a gridview that has an "Approve" and "Deny" button on each row. When a button is clicked, the row disappears. The users don't like this method because they lose their place when the page is reloaded. They'd like a check box, indicating approval, on each row and a "Save" button that they'd click when they've finished the whole list. How do I add such an unbound check box and process each row when the save button is clicked?
