ViewBag.countrydrop = item8;
return View();

i dont know where im wrong ,can anyone help me thanks in advance


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
