ASP.NET MVC เราจะนำข้อมูลหลายๆ Table ไปใส่ในหลายๆ DropdownListFor ที่อยู่ใน View เดียวกัน

namespace ProjectName.Models
{
    public class AllDropdownlist
    {
        public ITA_M_AGREEMENT agreement { get; set; }
        public ITA_M_CATEGORY category { get; set; }
        public ITA_M_DEPARTMENT department { get; set; }
        public ITA_M_GROUPTEAM groupteam { get; set; }
        public ITA_M_LOCATION location { get; set; }
        public ITA_M_STATUS status { get; set; }
        public ITA_M_TEAM team { get; set; }
        public ITA_M_TYPE type { get; set; }
        public ITA_M_MANUFACTURER manufacturer { get; set; }

        
    }
}

namespace ProjectName.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult Menu()
        {
            return View();
        }

        public ActionResult Hardware()
        {
            return View();
        }

        public ActionResult Software()
        {
            ITAssetEntities db = new ITAssetEntities();
            AllDropdownlist allDDL = new AllDropdownlist();

            allDDL.agreement = getAgreement();
            allDDL.manufacturer = getMenufacturer();
            allDDL.category = getCategory();
            allDDL.department = getDepartment();
            allDDL.groupteam = getGroupteam();
            allDDL.location = getLocation();
            allDDL.status = getStatus();
            allDDL.team = getTeam();
            allDDL.type = getType();


            return View(allDDL);
        }
}
