C# – There is no ViewData item of type ‘IEnumerable‘ that has the key country


While binding dropdown in MVC, I always get this error: There is no ViewData item of type 'IEnumerable<SelectListItem>' that has the key country.


@Html.DropDownList("country", (IEnumerable<SelectListItem>)ViewBag.countrydrop,"Select country")


List<Companyregister> coun = new List<Companyregister>();
coun = ds.getcountry();

List<SelectListItem> item8 = new List<SelectListItem>();
foreach( var c in coun )
    item8.Add(new SelectListItem
        Text = c.country,
        Value = c.countryid.ToString()

ViewBag.countrydrop = item8;
return View();

I don't know how to resolve it.

Best Answer

In your action change ViewBag.countrydrop = item8 to ViewBag.country = item8;and in View write like this:

                   "Select country")

Actually when you write

@Html.DropDownList("country", (IEnumerable)ViewBag.country, "Select country")


Html.DropDownList("country","Select Country)

it looks in for IEnumerable<SelectListItem> in ViewBag with key country, you can also use this overload in this case:

@Html.DropDownList("country","Select country") // it will look for ViewBag.country and populates dropdown
