摘要:MVC 動態新增select list(dropdown list)到view中 (for 新增,修改頁面)

01.先在controller頂端創造一個class


public class MemberController : Controller
    {
        //會員類別
        public class accessID
        {
            public int aID { get; set; }
            public string Name { get; set; }
        }

02.在Action Result中動態加入dropdownlist的值


public ActionResult Add()
        {
            MANAGER_DATA_RegisterModel mdr = new MANAGER_DATA_RegisterModel();

            //動態創造select,加入狀態
            List ls = new List();
            ls.Add(new accessID { aID = 1, Name = "test" });
            ls.Add(new accessID { aID = 2, Name = "test2" });
            IEnumerable accessIDs = ls;
            SelectList sl = new SelectList(accessIDs, "aID", "Name");
            ViewData["sl"] = sl;

            return View(mdr);
        }

03.在view中接收controller傳來的VIEWDATA


@Html.DropDownListFor(m => m.MA_ID, (SelectList)ViewData["sl"])
