I'm trying to bind a GridView control to a business object using the WebBusinessBindingSource object. I get the WBBS object added to my ASP.NET page with no problem and tell it which business object to use. However, when I bind the GridView to the WBBS, I get an ArgumentNullException (see the attached image).



Is there a property I need to change to make the GridView work with the WBBS?



Thanks!
