Collapse/Expand in Queries

Question

Hello,
I wish to create a query that gives the user the ability of expanding and collapsing data. I would like to display the invoices grouped by customer id and show the total amount for each customer. Optionally, the user could expand that customer row and visualize what the invoices that compose the total amount displayed are.
Something like this:
Customer 001 - 5,000.00
Customer 002 - 1,000.00
Expanding the firt row:
Customer 001 - 5,000.00
             Inv 1 -  2,000.00
             Inv 2 -  2,000.00
             Inv 3 -  1,000.00
Customer 002 - 1,000.00
Is it possible to do it using Query Generator/Query Wizard ? Or should I code this funcionality with SDK ?
Thanks in advance for any help

Hi Salim,
You can partially do that.  The SDK comes with a control called Grid, look at the SDK Help Center or the SDK samples for further info. The problem is that once grouped, you can't write anything else that the group name in that row. In your example, you won't be able to do
Customer 001 - 5,000.00
Inv 1 - 2,000.00
Inv 2 - 2,000.00
Inv 3 - 1,000.00
but you would have
Customer 001
Inv 1 - 2,000.00
Inv 2 - 2,000.00
Inv 3 - 1,000.00
or just
Customer 001 - 5,000.00
HTH,
