Active Report - Several reports in the same viewer ??

Hi,

I have a application which has a printing option allowing the user to print from 1 to 3 copies.

Copy 1: Client
Copy 2: Vendor
Copy 3: Archive

The 3 options are Checkboxes on my WinForm.

If the user checks all 3 options, I want to print the report (invoice) 3 times. They have slight differences but they all use the same dataset.

I don't want to have 3 viewer to popup. I really would like to have the 3 invoices(reports) within the same viewer.

I tried putting 3 sub-report in a main report. Each sub-report being an invoice, but since they use the same dataset, it doesn't work properly.

Does anyony have a solution for me? or a way to send 3 reports to the same viewer.

Thanks for helping.
