Dropdownlist in MVC3 (asp.net, c#) and submit the selected result

I have a class called Partner, that I need to Submit all the info from the View.

The Drop Down list needs to be filled by a dataset and on submit I want to fill SelectedHeardAboutText with the selected drop down item.

Here is my class:

public class Partner
{
        public string Name { get; set; }
        public string SelectedHeardAboutText { get; set; }
        public IEnumerable<SelectListItem> HowDidYouHear { get; set; }
}

Here is my PartnerController:

public ActionResult Partner() {

    var hear = db.HowDidYouHears.ToList();
    var partner = new Partner();
    ViewBag.Hear = hear;

    return View(partner);
}

How would I go about creating my drop down on the view, my view model is bassed on the Partner class?

@Html.DropDownList(
    "SelectedHeardAboutText", 
    new SelectList((IEnumerable<Hear>)ViewBag.Hear, "Value", "Text")
)

Obviously that's ugly and I don't recommend it. Don't even know why I am posting it. Probably to say that it should never be used.

Here's the correct way to do it (by using strongly typed view):

public ActionResult Partner() 
{
    var partner = new Partner
    {
        HowDidYouHear = db.HowDidYouHears.Select(x => new SelectListItem
        {
            Value = x.Id, // this will be used as value
            Text = x.SomeTextProperty // this will be used as text
        })
    };
    return View(partner);
}

and in your view:

@Html.DropDownListFor(
    x => x.SelectedHeardAboutText, 
    new SelectList(Model.Hear, "Value", "Text")
)
