SummaryRow CheckBox itemRenderer in AdvanceDataGrid

[theHighTechHorseGuy]

i have an advanceddatagrid filled with orders. it is grouped by customer, then
by orderID. (you can see it here: [url]https://www.edgalemba.com/Orders/test2.html[/url])

anyway, in my grid i have a 'Shipped' checkbox next to each item in an order
because sometimes items are backordered. i'd like the check box that appears in
the orderID SummaryRow to select all of the checkboxes for the items that
belong to that order when selected.

this would act like a headerRenderer but only for each group.

any suggestions?
