MVC Wymagane sprawdzanie poprawności pola nie działa

Question

Wymagane sprawdzanie poprawności pola bez uruchamiania.

Model:

public class Client 
    { 
     [Required(ErrorMessage="Name Required")] 
     [DisplayFormat(ConvertEmptyStringToNull = false)] 
     public string Name { get; set; } 
     public string Address { get; set; } 
     public string Mobile { get; set; } 
     public string Telephone { get; set; } 
     public string Fax { get; set; } 
     public string Company { get; set; } 
    } 

Kontroler:

[HttpPost] 
     public ActionResult Create(Client client) 
     { 
      try 
      { 
       // TODO: Add insert logic here 
       ClientRepository rep = new ClientRepository(); 
       rep.AddClient(client); 
       rep.Save(); 
       return RedirectToAction("Index"); 
      } 
      catch 
      { 
       return View(); 
      } 
     }
