Can any one please help here! In my application I have a view which is rendering a number of partial views. Whenever I am adding a particular view say a.ascx and trying to submit the FORM I start getting this error. The control is not being passed to the action method as I have added a breakpoint there getting the error from the view itself. Checked the respective models but no repetition of property or method found. Any help in this regard will be very much helpful, I have spent 2 days on this already.
