Use Viewbag is wrong for sending list to view.You should using Viewmodel in this case. like this:
Send Country list and City list and Other list you need to show in View:
HomeController Code:
[HttpGet]
public ActionResult NewAgahi() // New Advertising
{
//--------------------------------------------------------
// استفاده از ویومدل برای نمایش چند مدل در ویو
Country_Repository blCountry = new Country_Repository();
Ostan_Repository blOstan = new Ostan_Repository();
City_Repository blCity = new City_Repository();
Mahale_Repository blMahale = new Mahale_Repository();
Agahi_Repository blAgahi = new Agahi_Repository();
var vm = new NewAgahi_ViewModel();
vm.Country = blCountry.Select();
vm.Ostan = blOstan.Select();
vm.City = blCity.Select();
vm.Mahale = blMahale.Select();
//vm.Agahi = blAgahi.Select();
return View(vm);
}
[ValidateAntiForgeryToken]
[HttpPost]
public ActionResult NewAgahi(Agahi agahi)
{
if (ModelState.IsValid == true)
{
Agahi_Repository blAgahi = new Agahi_Repository();
agahi.Date = DateTime.Now.Date;
agahi.UserId = 1048;
agahi.GroupId = 1;
if (blAgahi.Add(agahi) == true)
{
//Success
return JavaScript("alert('ثبت شد')");
}
else

//Fail
return JavaScript("alert('اشکال در ثبت')");
}
