        {
            if (ValidateMasterDetailForm())
            {
                int _OrderNO1 = 0;
                using (SqlConnection sqlCon = new SqlConnection(strConnectionString))
                {
                    sqlCon.Open();
                    //Master[SalesOrderAddOrEdit]
                    //string q = "INSERT INTO SalesOrder(Order_Ref_No,CustomerID,Order_date,Status) VALUES(@Order_Ref_No, @CustomerID, @Order_date, @Status)";
                    SqlCommand sqlCmd = new SqlCommand("[InsertSalesOrderAddOrEdit]", sqlCon);
                    sqlCmd.CommandType = CommandType.StoredProcedure;
                    sqlCmd.Parameters.AddWithValue("@OrderNo", inorderNO1);
                    sqlCmd.Parameters.AddWithValue("@Order_Ref_No", txtOrderRefNo.Text.Trim());
                    sqlCmd.Parameters.AddWithValue("@CustomerID", Convert.ToInt32(cmbCustomerName.SelectedValue.ToString()));
                    sqlCmd.Parameters.AddWithValue("@Order_date", dateTimePicker1.Value);
                    //sqlCmd.Parameters.AddWithValue("@SOpirority", txtSO.Text.Trim());
                    sqlCmd.Parameters.AddWithValue("@Status", cmbStatus.Text);

                    _OrderNO1 = Convert.ToInt32(sqlCmd.ExecuteScalar());
                }
                //Details
