Two buttons: "Back" and "Next"

Question

Hi!


I need to scroll my datas with these buttons ("Back" and "Next"). With these codes how can I scrolling my datas showing on my textboxes.

conn = new OleDbConnection(connstr);

            comm = new OleDbCommand();

            conn.Open();

            OleDbParameter date = new OleDbParameter("@date", SqlDbType.VarChar);

            OleDbParameter cod = new OleDbParameter("@cod", SqlDbType.VarChar);

            OleDbParameter name = new OleDbParameter("@name", SqlDbType.VarChar);            

            comm.Parameters.Add(date);

            comm.Parameters.Add(cod);

            comm.Parameters.Add(name);

            date.Value = dateTimePicker2.Text;

            cod.Value = txtCode.Text;

            name.Value = txtWork.Text;            

            comm.Connection = conn;

            comm.CommandText = "insert into power ([date],[cod],[name]) values(@date,@cod,@name)";

            

            try

            {

                comm.ExecuteNonQuery();

                MessageBox.Show("Saved...");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

            finally

            {

                conn.Close();
