ERROR TYPE: Output false false false for @Html.EditorFor(model => model.Items)

Expected Result: Listbox with the name of users.

ViewModel

public class NewVariance
    {
        MVRLinqDataContext LinqCtx = new MVRLinqDataContext()
        public NewVariance()
        {
            IndividualsObjectTest();//load data dropdown and listbox data
        }

        public MultiSelectList Items { get; set; }

        //loads the values of the MultiSelectList above
        public void IndividualsObjectTest()
        {
            var IndividualsDropDownList =
                        (
                        from x in LinqCtx.ViewIndividualDropDownBoxes
                        orderby x.FullName
                        select x);

               Items = new MultiSelectList
              (
                IndividualsDropDownList as 
System.Collections.IEnumerable, "First_Hospital_Case_Nbr", "FullName"

              );

        }

Controller

public class NewVarianceController : Controller
    {
        public ActionResult Index()
       {
              var model = new NewVariance();
              return View(new model);
        }

    }

View

@Html.ListBox("d",Model.Items)   THIS WORKS 
    @Html.EditorFor(model => model.Items) THIS DOESNT WORK OUTPUTS FALSE FALSE FALSE 

Answer 1

An editor template simply renders some default output based on the property type. You need to personalize it if you expect to do something useful. You can read more about templated helpers on this blog post. You cannot expect that a default editor template would know that you want it to render a listbox for this given property. So you could write a custom editor template and personalize this behavior.
