SqlConnection con = new SqlConnection("Data Source=" + value1 + ";Initial Catalog=" + value2 + ";User ID=" + value3 + ";Password=" + value4 + "");// DataRow dr;
dr = dt.NewRow();
dr.ItemArray = new object[] { 0, "---Select Nationality---" };
dt.Rows.InsertAt(dr, 0);
comboBox2.DisplayMember = "NationalityName";
comboBox2.ValueMember = "NationalityID";
comboBox2.DataSource = dt;
