Create Table Country
(
 CountryID int not null,
 CountryName varchar(50) not null
)
insert into Country Values(1,'India')
insert into Country Values(2,'USA')

2- Create a New MVC Project named BindDropDownMVC3 with Razor ViewEngion. in Models Folder add a EDMX file and add Country TAble in EDMX.



3- Add a Model Class named CountryModel.cs. below are the Code specified....


public class CountryModel
    {
        public string Country { get; set; }

        public List<SelectListItem> Countrylist { get; set; }

        public void SetCountryList(List<Country> countries)
        {
            List<SelectListItem> items = new List<SelectListItem>();
            countries.ToList().ForEach(s =>
            {
                items.Add(new SelectListItem()
                {
                    Text = s.CountryName.ToString(),
                    Value = s.CountryID.ToString()
                });
            });
            this.Countrylist = items;
        }

    }

4- in DefaultController.cs add the Following Code 

using BindDropDownMVC3.Models;

public class DefaultController : Controller
    {
        EmployeeDataEntities ed= new EmployeeDataEntities ();
        //
        // GET: /Default/

        public ActionResult Index()
        {
            CountryModel cm = new CountryModel();
            cm.SetCountryList(GetCountries());
            return View(cm);
        }

        public List<Country> GetCountries()
        {
           return (from c in ed.Countries.OrderBy(x=> x.CountryID) select c).ToList();
        }
    }

5- Now in Index.cshtml add the Following Code

@model BindDropDownMVC3.Models.CountryModel
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

 @Html.DropDownListFor(model => model.Country, Model.Countrylist, new { @id = "countryid", style = "font-family:Calibri;width: 213px; border: 1px solid #828282;"})
