Get selected value from Dropdownlist

Hi guys how can one get selected value?

Here is my model

public class PaymentModels
{
    public int CreditCardNumber { get; set; }
    public List<SelectListItem> CardType { get; set; }

    public static List<SelectListItem> getCardTypes()
    {
        List<SelectListItem> cardType = new List<SelectListItem>();
        cardType.Add(new SelectListItem { Text = "American Express"});
        cardType.Add(new SelectListItem { Text = "Mastercard" });
        cardType.Add(new SelectListItem { Text = "Visa" });

        return cardType;
    }
}

This is how the list is shown on view via controller

ViewData["List"] = PaymentModels.getCardTypes();

And here is my post back method

[HttpPost]
public ActionResult Payment(PaymentModels pay)
{
    String vr;
    foreach(var v in pay.CardType) {
        vr= v.Selected.ToString();
    }

    return View();
}

My question is that how can i get the selected value from my cardtype list when post event is invoked?

You need to add values to your items, not only text:

public static List<SelectListItem> getCardTypes()
{
    List<SelectListItem> cardType = new List<SelectListItem>();
    cardType.Add(new SelectListItem { Value = "1", Text = "American Express" });
    cardType.Add(new SelectListItem { Value = "2", Text = "Mastercard" });
    cardType.Add(new SelectListItem { Value = "3", Text = "Visa" });

    return cardType;
}

Now you could simply add a property on your view model:

public int SelectedCardType { get; set; }

And in the view:

<%= Html.DropDownListFor(
    x => x.SelectedCardType, 
    (IEnumerable<SelectListItem>)ViewData["list"]
) %>

and in your controller action:

[HttpPost]
public ActionResult Payment(PaymentModels pay)
{
    // pay.SelectedCardType will contain the selected value (1, 2 or 3)
    ...
}

Of course the values should not necessary be integers. You could use a string property as well:

public static List<SelectListItem> getCardTypes()
{
    List<SelectListItem> cardType = new List<SelectListItem>();
    cardType.Add(new SelectListItem { Value = "American Express", Text = "American Express" });
    cardType.Add(new SelectListItem { Value = "Mastercard", Text = "Mastercard" });
    cardType.Add(new SelectListItem { Value = "Visa", Text = "Visa" });

    return cardType;
}

and:

public string SelectedCardType { get; set; }
