Required field validation not firing.

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; }
    }

Controller:

 [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();

Use ModelState.IsValid property

public ActionResult Create(Client client)
{

  if(ModelState.IsValid)
   {
   // TODO: Add code here
      ClientRepository rep = new ClientRepository();
      rep.AddClient(client);
      rep.Save();
      return RedirectToAction("Index");
   }
   return View(client);
}
