PRINT & EXPORT report in asp.net

HI ALL,
i am designing some reports in cr10 for asp.net (code behind vb.net). Problem is that PRINT & EXPORT buttons on CrystalReportViewer object is not working. Is i have to write any special code for that.

THANKS IN ADVANCE

:cry:

How do you mean its not working? Errors or nothing happens or the export format of choice is not displayed in the export list?

HI ALL,
IN cr10.0 when i clicked on export & print button of crystalreport object nothing happens. no error just it open new window(wizard) for export option asking for export format but when click on 'OK' nothing happen same with print option.
Is i have to write any special code for PRINT & EXPORT option that.

Have you tried to export them manually?

VB Code:

crReportDocument.ExportToDisk(ExportFormatType.PortableDocFormat, "c:\test.pdf")

Regards
Jorge

crReportDocument.ExportToDisk this code work in only .net windows application and not in web app
THANKS LOT
