Multiple Sub Report in ReportViewer

Hi, i face a problem in printing a report from report viewer with two sub report.My report layout is as below:

Parent Report
-------
Body Section

SubReport1 SubReport2

I have successfully created the report and the result is correct.But when i come to the print preview mode or printing the report, i can only see the result form SubReport1, the result from SubReport2 is gone.I have tested that SubReport2 is working fine and it can be seen in print preview mode or printed paper if the SubReport1 is taken out from the parent report.Finally i find out, i can only see only 1 SubReport result in print preview mode or printed paper depending on which subreport is draggged first to the parent.Does anyone has idea on this?
