Hey guys,

I am trying to create a pretty straightforward webschedule page and I keep getting this:

An exception of type 'System.ArgumentNullException' occurred in System.Web.dll but was not handled in user code

Additional information: Value cannot be null.

The odd thing is that when I set up the webschedule stuff in another (simple) project, it works. I use the same SqlDataSource and WebScheduleSqlClientProvider. The only difference is that in the first project, I'm using the supervising controller pattern and having the controller make a call to the view's DataBind method when the page loads and that's where the exception gets thrown.

Any help would be greatly appreciated.

Thanks,

Ilija 

Edit:

When I remove the call to DataBind, I end up with this error:

The strange thing about this is that I'm using the exact same connection string as in the other project and it works in that one...
