Thanks guys, I believe I would want the total to update itself as the user is changing the quantity, and not when they finish editing, but it's a temporary solution though. I didn't think about the editing part since I was stressing on the change event. If anyone else knows how I can code up the change event to my ArrayCollection in a datagrid so that the total gets updated promptly, PLEASE PLEASE PLEASE HELP ME!!!
