        {
            List<TenderKhabarCRM.Models.Status> status = new List<TenderKhabarCRM.Models.Status>();
            status = TenderKhabarCRM.DAL.DAL.GetAllStatus();
            ViewBag.StatusList = new SelectList(status, "StatusID", "StatusName");
 return PartialView(status);
        }

public static List<Status> GetAllStatus()
        {
            SqlDataReader reader = null;
            SqlParameter[] sqlParameter = new SqlParameter[] { };
            List<Status> statusList = new List<Status>();
            try
            {
                reader = DalSqlHelper.ExecuteReader(connectionString, CommandType.StoredProcedure, "spGetAllStatus", sqlParameter);

                while (reader.Read())
                {
                    TenderKhabarCRM.Models.Status status = MapStatusObject(reader);
                    statusList.Add(status);
                }
            }
            finally
            {
                if (reader != null && !reader.IsClosed)
                {
                    reader.Close();
                    reader = null;
                }
            }
            return statusList;
        }

推荐答案

我已经创建了一个工作正常的样本。请尝试这样做/>

I have created an sample which works fine.Please try like that

public class TestController : Controller
    {
        //
        // GET: /Test/

        public ActionResult Index()
        {

            ViewBag.StatusList =
                           DropDownList<Status>.LoadItems(GetData(), "StatusId", "Name");
            return View();
        }
        public ActionResult _PartialView()
        {
            return PartialView();
        }
       public List<Status>  GetData()
       {
           var list = new List<Status> {new Status() {StatusId = 1, Name = "AAA"}};
           return list;
       }
    }
    public class  Status
    {
        public decimal StatusId { get; set; }
        public string Name { get; set; }
    }
    public class MyViewModel
    {
        public int StatusId { get; set; }
    }
    public static class DropDownList<T>
    {
        public static SelectList LoadItems(IList<T> collection, string value, string text)
        {
            return new SelectList(collection, value, text);
        }
    }

部分查看代码

Partial View code

@model MvcApplication1.Controllers.MyViewModel

 @Html.DropDownListFor(model => model.StatusId, (IEnumerable<SelectListItem>)ViewBag.StatusList, "--Select--", new { @class = "select" })

索引视图

Index View

@model MvcApplication1.Controllers.MyViewModel
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>
@Html.Partial("_PartialView")

注意：请确保部分视图应位于View>>测试>内;>文件夹

希望这有帮助

Note: Please make sure that partial view should be inside of View>>Test>> folder
Hope this helps
