Hi,
 
The below code shows how to pass the paramater and export it to the PDF format...
This message is appering when you try to export report and having parameters in that report...
Passing the paramter in below format will export the report without any errors...

' The Below code passes parameter to Crystal Report

Dim discretevalue As ParameterDiscreteValue

Dim values As ParameterValues

discretevalue = New ParameterDiscreteValue

discretevalue.Value = "Imtiaz" ' Assign parameter

values = New ParameterValues

values.Add(discretevalue)

crReportDocument.DataDefinition.ParameterFields(0).ApplyCurrentValues(values)

' The below code converst into PDF file format

Dim oStream As New MemoryStream

oStream = crReportDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)

Response.Clear()

Response.Buffer = True

Response.ContentType = "application/pdf"

Response.BinaryWrite(oStream.ToArray())
