I have a small project done in ASP.NET MVC 4 that us using SQL and using Razor View engine , it is working to some extent
I have added to it few webforms as I needed to use some controlers from the webform

I want to call the webform within the Razor view as partial view

the applicaiton work with some controlers like buttons , lists..ets

however, when I add charts it gives me errors "Exception Details: System.NullReferenceException: Object reference not set to an instance of an object."

and will work only if I put it inside an IFRAME
