    public StudentFullRegistrationViewModel StudentFullRegistrationViewModel { get; set; }
}

thts one also not working .please help me?

Answer 1

this is why your combo has member user is IEnumerable of Users

 public IEnumerable<User> User { get; set; }

so you have more than one user which cannot have only single control to manipulate them (all your users) so if your need is to have single user just change your class definition to

 public User User { get; set; }

or if you are in need to have multiple user objects so use foreach and bind each of your user object to single control
