Here is an older email from the brilliant Mac Kloberg that explains how =
to
do this. This used Beta 2 software, so there may be a few changes.

Jim,
as far as I know, the webviewer doesn't support exporting directly, so =
you
have to do do this yourself. I haven't found a way yet to do this
"in-memory", so the following example uses a temporary file (using the
session id as the filename). It sends the report to the client as a PDF
file, but you can easily change it to export in different formats:

Dim TargetFildName as String
Dim fs As FileStream
Dim FileSize As Long
Dim GenDS As DataSet
Dim oRD As New ReportDocument()
Dim crReportObject As =
CrystalDecisions.CrystalReports.Engine.ReportObject
Dim oExO As ExportOptions
Dim oExDo As New DiskFileDestinationOptions()

'Build Target Filename
TargetFileName =3D Server.MapPath("/") & "\Export\" & Session.SessionID =
&
".pdf"

'Load report
oRD.Load(Server.MapPath("/") & "\Reports\MyReport.rpt")

'Set Report Datasource
oRD.SetDataSource(GenDS)

'Export to PDF
oExDo.DiskFileName =3D TargetFileName
oExO =3D oRD.ExportOptions
oExO.ExportDestinationType =3D ExportDestinationType.DiskFile
oExO.ExportFormatType =3D ExportFormatType.PortableDocFormat
oExO.DestinationOptions =3D oExDo
oRD.Export()
oRD.Close()

'Send the file to the user that made the request
Response.Clear()
Response.Buffer =3D True
Response.AddHeader("Content-Type", "application/pdf")
Response.AddHeader("Content-Disposition", "attachment;
filename=3DMyReport.pdf;")
fs =3D New FileStream(TargetFileName, FileMode.Open)
FileSize =3D fs.Length
Dim bBuffer(CInt(FileSize)) As Byte
fs.Read(bBuffer, 0, CInt(FileSize))
fs.Close()

Response.BinaryWrite(bBuffer)
Response.Flush()
Response.Close()
