I have here a code for dropdownlist to present data from the database.

Code:
                DataTable dtCountry = new DataTable();

                daCountry.Fill(dtCountry);

                countryList.DataSource = dtCountry;
                countryList.DataTextField = "Country";
                countryList.DataValueField = "CountryID";
                string countryID = clusterList.SelectedValue;
What about the code for textBox? Many thanks!!!
