Hi roxylalondef,

As far as I think,you could create multiple post methods and multiple models.

Just like this:

public ActionResult Index()  
        {  
            return View();  
        }  
  
        public ActionResult AC()  
        {  
            return View(....);  
         } 
        [HttpPost]  
        public ActionResult A1()  
        {  
            ... 
            return View(....);  
        }  
        [HttpPost]  
        public ActionResult A2()  
        {  
            ....
            return View(...);  
        }  
        public ActionResult Success(string message)  
        {  
            ViewBag.Message = message;  
            return View();  
        }  
  
        public ActionResult About()  
        {  
            ViewBag.Message = "Your application description page.";  
  
            return View();  
        }  
  
        public ActionResult Contact()  
        {  
            ViewBag.Message = "Your contact page.";  
  
            return View();  
        }
