Validation Failed For One or More Entities: MVC/Entity Framework 5.0


In the database I restricted the Name column data Type to nvarchar(10) and I was inserting the value that has more than 10 characters.
Then Above Error was Occured.

used the code as shown below to identify the root cause.

public ActionResult Create(EmpRegistration collection)  

{  

    try  

    {  

         

    }  

    catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)  

    {  

        Exception raise = dbEx;  

        foreach (var validationErrors in dbEx.EntityValidationErrors)  

        {  

            foreach (var validationError in validationErrors.ValidationErrors)  

            {  

                string message = string.Format("{0}:{1}",  

                    validationErrors.Entry.Entity.ToString(),  

                    validationError.ErrorMessage);  

                // raise a new exception nesting  

                // the current instance as InnerException  

                raise = new InvalidOperationException(message, raise);  

            }  

        }  

        throw raise;  

    }  

}  

public ActionResult Create(EmpRegistration collection)  

{  

    try  

    {  

        if (ModelState.IsValid)  

        {  

            EmpRegistration empRegis = new EmpRegistration();  

            // TODO: Add insert logic here  

            empRegis.Address = collection.Address;  

            empRegis.City = collection.City;  

            empRegis.Id = 7;  

            empRegis.Name = collection.Name;  

            objEnity.EmpRegistrations.Add(empRegis);  

            objEnity.SaveChanges();  

  

            return View();  

        }  

        return View(objEnity.EmpRegistrations);  

    }  

    catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)  

    {  

        Exception raise = dbEx;  

        foreach (var validationErrors in dbEx.EntityValidationErrors)  

        {  

            foreach (var validationError in validationErrors.ValidationErrors)  

            {  

                string message = string.Format("{0}:{1}",  

                    validationErrors.Entry.Entity.ToString(),  

                    validationError.ErrorMessage);  

                // raise a new exception nesting
