bind country name using entity

Thanks for reply

but my question is in the first page iam saving the details to db

but in next page i want bind the values from database in page load

but when iam saving the details into db that time iam passing the country value as countryid

ex:
----
ddlcountry.datatextfield="countryname";
ddlcountry.datavaluefield="countryid";
-----------------------------

but in the next i want to disply country name

from same table


iam binding the latest record from db using select top(1) * from tablename orederby id desc


so if is there any way

protected void BindCountryName()
{
    using(var dc = new DbContext())
    {
        dd1.DataSource = from p in dc.countries
                         orderby 0
                         select new {p.CountryName}.ToList();
        dd1.DataTextField = "CountryName";
        dd1.DataValueField = "CountryName";
        dd1.DataBind();
    }
}

or

 dd1.DataSource = dc.countries.Select( p => new {p.CountryName}).Distinct().ToList();
dd1.DataTextField = "CountryName";
dd1.DataValueField = "CountryName";
 dd1.DataBind();
