Overload

Controller Action Method

public ActionResult DropDownListFor()
{
    ViewBag.Doors = new SelectList(
                        new[]
                        {
                            new {Value = 1,Text="1-Door"},
                            new {Value = 2,Text="2-Door"},
                            new {Value = 3,Text="4-Door"},
                            new {Value = 4,Text="4-Door"},
                            new {Value = 5,Text="5-Door"},
                            new {Value = 6,Text="6-Door"},
                            new {Value = 7,Text="7-Doors"}
                        }, "Value", "Text", 7);
    return View();
}

View

@Html.DropDownList("Doors")

How will I do it using SelectListItem?

Action Method

[HttpGet]
public ActionResult DropDownListFor()
{
    List items = new List();

    items.Add(new SelectListItem { Text = "Action", Value = "0" });
    items.Add(new SelectListItem { Text = "Drama", Value = "1" });
    items.Add(new SelectListItem { Text = "Comedy", Value = "2", 
                                                             Selected = true });
    items.Add(new SelectListItem { Text = "Science Fiction", Value = "3" });
    ViewBag.MovieType = items;

    return View();
}

View

@using (Html.BeginForm("Action", "Controller", FormMethod.Post))
{
    @Html.DropDownList("MovieType")
}

How will I do it using View Model?

View

@using (Html.BeginForm("Action", "Controller", FormMethod.Post))
{
    @Html.DropDownListFor(m => m.Id, Model.DDLList, "Please select");
}

Action Method

[HttpGet]
public ActionResult DropDownListFor()
{
    return View(new Models.Dropdown());
}

View Model

public class Dropdown
{
    public string Id { get; set; }
    public List DDLList
    {
        get
        {
            return new List() 
            { 
                new SelectListItem
                { 
                    Text = "1-Door", 
                    Value = "1", 
                    Selected = true
                },
                new SelectListItem
                { 
                    Selected = false, 
                    Value = "2", 
                    Text = "2-Door"
                }
            };
        }
    }
}
