ModelState.AddModelError NullReferenceException (ASP.Net MVC Validations)

While trying to add validation errors to the ModelState using the AddModelError method, I was getting “NullReferenceException” run time errors. After doing some research I found that if we follow the AddModelError with SetModelValue method as shown by the highlighted line below, the system doesn’t throw runtime NullReferenceException anymore. ModelState.AddModelError(PropertyName, ErrorMessage); ModelState.SetModelValue(PropertyName,ValueProvider[PropertyName]);
