Have an asp.net app and am writing insert, update and delete operations for a details view
My insert works great, now I'm trying to do the update, but I'm getting YSOD when I press the update button. There's only one date on the form and that uses exactly same template for insert and edit. Below is the asp and stack trace and from what I can see it's not in any of my subs at this point:
