I developed a report in Crystal 9 containing 3 groups (year, month and storeID), its working very well in Crystal. But when I try to it open in visual basic.net (using CrystalReportsViewer), the viewer doesn't show anything).
If I delete the groups in the report, the report is working in the viewer (of course it shows me a blank report).
Do groups are not supported in CrystalReportsViewer?
Does anyone have a clue how to solve this kind of problem?
