Have you tried using Data Annotations in your model to mark the property as required?

[Required(ErrorMessage = "You must select a State")]

Are you exposing the StateId as a part of the Model? If so that's where you should set the Required Attribute, like so:

    [Required(ErrorMessage = "You must select a State")]
    public int StateId { get; set; }
