Asp net detailview itemupdating
I'm having the same problem, and it does appear related to the fact that I'm using Read Only mode, but not as my default mode. Originally, all my Form Views' default Mode was Edit, and I occaisionally changed that to Add.
Here is a link to the source code: State Error/View State I believe it's a bug. If I start out with the Edit Mode as the Default Mode, and then make sure that the Form View never goes back into the Read Only mode, then it seems to work.I'm getting this same problem but the form view state won't work. When I let the detail view return to it's post update state and then give them a link to get back to the full list it does not cause this error. Thanks so much mokeefe, I've always relied on the kindness of strangers. Right now the form does not have an Insert Template but I will be adding it shortly.I really hope this puts the viewstate loading problem to rest, and I think there are some bugs in this area of the control.
