Hello,

Assume I have a grid of Invoices. The grid is grouped by invoice number with the child rows being the detail line items for each invoice.

Invoice # 1000 - Customer B
....line item 1
....line item 2
....line item 3
Invoice # 1004 - Customer A
....line item 1
....line item 2
Invoice # 1007 - Customer C
....line item 1
....line item 2
....line item 3
....line item 4

When the group row is created, I can choose to sort the group row in ascending or descending order.

Is it possible to sort the group rows by the customer name?

Invoice # 1004 - Customer A
....line item 1
....line item 2
Invoice # 1000 - Customer B
....line item 1
....line item 2
....line item 3
Invoice # 1007 - Customer C
....line item 1
....line item 2
....line item 3
....line item 4

Thanks.

I think you can use the custom sort type (igSortCustom) and implement custom sorting for that column in the CustomSort event.
