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

C#

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);
        }
    }

Partial View code

C#

@model MvcApplication1.Controllers.MyViewModel

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

Index View

C#

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

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

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