MVC Disabled SelectListItem property not working

Building the SelectList

   public SelectList DummyList()
    {
        List<SelectListItem> list = new List<SelectListItem>();
        list.Add(new SelectListItem { Value = "0", Text = "---Select--", Disabled = false });
        list.Add(new SelectListItem { Value = "Uno", Text = "Uno", Disabled = false });
        list.Add(new SelectListItem { Value = "Dos", Text = "Dos", Disabled = true});
        list.Add(new SelectListItem { Value = "Tres", Text = "Tres", Disabled = false });
        list.Add(new SelectListItem { Value = "Cuatro", Text = "Cuatro", Disabled = false });

        return new  SelectList(list, "Value", "Text", "---Select--");

    }



Binding the Select List to the model

model.ProductsModel.Model = new DummyDropDown().DummyList();



Displaying the view

@Html.DropDownListFor(model => model.Model, Model.Model, htmlAttributes: new { @class = "dropdown ", @style = "width:50%;" })



Html Result

<select id="Model" class="dropdown " style="width:50%;" name="Model">
   <option value="0">---Select--</option>
   <option value="Uno">Uno</option>
   <option value="Dos">Dos</option>
   <option value="Tres">Tres</option>
   <option value="Cuatro">Cuatro</option>
</select>



View

enter image description here


The Select List is displaying all the items enabled when in reality option "Dos" should be disabled 

<option value="Dos" disabled>Dos</option>

according to the properties.

If someone can explain why to me, or tell me what is wrong with the code. Is there any other way to achieve this? I need item "Dos" to be disabled (grayed out).

Thanks in advance.

Try changing your method to

public IEnumerable<SelectListItem> DummyList()
{
  List<SelectListItem> list = new List<SelectListItem>();
  ....
  list.Add(new SelectListItem { Value = "Dos", Text = "Dos", Disabled = true});
  ....
  return list;
}

and make ProductsModel.Model typeof IEnumerable<SelectListItem> rather than SelectList

Currently your creating a new SelectList based on your list using the properties Value and Text only (not taking into account the Disabled property). Alternatively you can use one of the SelectList overloads that accepts parameter IEnumerable of disabled values
