I can’t seem to get my details view to enter edit mode. I am programatically binding the data source. When the item command is “edit” I change the mode to “edit” and rebind the datasource. I checked after the control databound and it’s still in edit mode, but the details view is not displaying in edit mode. Any help would be greatly appreciated. Currently my details view is simplified to one element for testing. (this is a cross post from ASP.NET forums, since I could use some help relatively soon)

I figured it out, it turns out my Telerik Ajax Manager was hiding the error I was getting. I was getting “The DetailsView fired event ModeChanging”, which I resolved using the instructions in the following link: forums.asp.net
