ASP.NET - EXPORTAR REPORTES DESDE UNA APLICACIÓN WEB AL USUA

TENGO UNA APLICACIÓN WEB ASPX QUE PRESENTA REPORTES DE CRYSTAL REPORTS, NECESITO EXPORTARLOS EN DIFERENTES FORMATOS (.DOC, .XLS, .PDF) Y AL HACERLO ME LO EXPORTA AL SERVIDOR PERO NO AL EQUIPO DE LOS USUARIOS.

ESTOY TRABAJANDO CON VISUAL.NET 2002.
EL CÓDIGO ES:

Sub ExportReport()
' This subroutine uses a case statement to determine the selected export format from the dropdownlist
' menu and then sets the appropriate export options for the selected export format. The report is
' exported to a subdirectory called "Exported".

' ********************************
'Check to see if the application directory has a subdirectory called "Exported".
'If not, create the directory since exported files will be placed here.
'This uses the Directory class of the System.IO namespace.

ExportPath = "C:\Exported\"
If Directory.Exists(ExportPath) = False Then
Directory.CreateDirectory("C:\Exported\")
End If
' ********************************

' First we must create a new instance of the diskfiledestinationoptions class and
' set variable called crExportOptions to the exportoptions class of the reportdocument.
crDiskFileDestinationOptions = New DiskFileDestinationOptions()
crExportOptions = crReportDocument.ExportOptions

'Find the export type specified in the dropdownlist and export the report. The possible export format
'types are Rich Text(RTF), Portable Document (PDF), MS Word (DOC), MS Excel (XLS), Crystal Report (RPT),
'HTML 3.2 (HTML) and HTML 4.0 (HTML)
'
'Though not used in this sample application, there are options that can be specified for various format types.
'When exporting to Rich Text, Word, or PDF, you can use the PdfRtfWordFormatOptions class to specify the
'first page, last page or page range to be exported.
'When exporting to Excel, you can use the ExcelFormatOptions class to specify export properties such as
'the column width etc.
