The composition of the drop down list box is as follows

ddl_Loan_Type.SelectedValue = ds.Tables["Loans"].Rows[0]
["LOANTYPE"].ToString();</pre>

  protected void Page_Load(object sender, EventArgs e)
        {

            if (!IsPostBack)
            {

                {
                    SqlConnection connect = new SqlConnection();
                    connect.ConnectionString = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
                    connect.Open();
                    SqlDataAdapter da = new SqlDataAdapter("select * from Loans order by idno", connect);

                    DataSet ds = new DataSet();
                    da.Fill(ds, "Loans");

                    txt_Id_Code.Text = ds.Tables["Loans"].Rows[0]["ID_CODE"].ToString();
