gönderdiği düzenlenmiş Nerede tam bir istisna atar? Görünümde veya kontrolörde mi? Denetleyicide bir JsonResult döndürme hakkında nasıl bir geri bildirim: Json (Data, JsonRequestBehavior.AllowGet); – Fabjan

Bana göre sen uygulayabileceğiniz en iyi şudur, bu kesinlikle sizin için çalışacaktır:

bu şekilde html değiştirme

: Öncelikle bu model için yukarıdaki modelini değiştirmek

@model List<CimenaCityProject.Models.MovieTheaters> 

@{ 
    var selectlist = (SelectList)ViewBag.HomeCinemaID; 
}

Sonra senin form böyle olmalı, Yaptığım değişiklikler, tüm editörlerinize ve her alana farklı bir ad verecek olan tüm açılır kapanır listelerine de endekslidir.

    $.ajax({ 
     url: '@Url.Action("Create","Home")',

     }, 
     error: function(result) { 
      alert(result.responseText + "Error") $('#divLoading').hide()

function success(result) {

Şimdi komut kodu Sadece jquery $('form:first').serializeArray(); bunu seri ederek bütün formu göndermek, böyle olmalı: i yazdım gibi açılan onların "Sizin Listesi" listenizi bağlamak unutmayın

Tümü tamamlandı, Kontrol ünitesi şimdi değerlerinizi alacak :)
