            //Here textbox10 = PersonID field in antenatal form.
            SqlConnection con = new SqlConnection(strConn);
            con.Open();
            SqlCommand cmd = new SqlCommand("sp_get_antenatal", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@person_id", textBox10.Text);
            SqlDataReader dr = cmd.ExecuteReader();
            if (dr.Read())
            {
                cbPlaceoforder.SelectedValue = dr["antenatal_care_id"].ToString();
