ASP.NET MVC- DropDownList綁定

　　看一下Controller例子

        [ChildActionOnly]
        public List<SelectListItem> LoadItemStatus()
        {
            List<SelectListItem> items = new List<SelectListItem>() { 
                new SelectListItem() { Value = "", Text = "--全部--" },
                new SelectListItem() { Value = "待審覈", Text = "--待審覈--" },
                new SelectListItem() { Value = "審覈經過", Text = "--審覈經過--" },
                new SelectListItem() { Value = "審覈不經過", Text = "--審覈不經過--" }
            };

            return items;
        }



        public ActionResult Index()
        {
            List<SelectListItem> items = new List<SelectListItem>() { 
                new SelectListItem() { Value = "", Text = "--全部--" },
                new SelectListItem() { Value = "待審覈", Text = "--待審覈--" },
                new SelectListItem() { Value = "審覈經過", Text = "--審覈經過--" },
                new SelectListItem() { Value = "審覈不經過", Text = "--審覈不經過--" }
            };


            ViewData["Categories"] = new SelectList(items, "Text", "Value");


            return View();
        }

　　看一下
