Export Report in Visual Studio 2005 don't show stored procedure parameters

[Mariana]

Hello,
I am exporting reports in pdf format from .net 2005 . The export is working fine; however the user values of stored procedure parameters does not show in the report. What do I need to do in order to see the parameters value in the report?

The report has a report parameter "reportTitl e" and i see the value in the report.
It has also another 2 stored procedure parameters @BeginDate and @EndDate.
The values are entered be the user; however in the report those values don't appear.


I used the following code:
[HTML]
//load the report
crReportDocumen t = new CrystalDecision s.CrystalReport s.Engine.Report Document();
crReportDocumen t.Load(Server.M apPath("\Report s\Production.rp t") ;
// set logins for the crystal report
Utilities.SetLo gons(crReportDo cument);
Hashtable reportParamsHas h = ((Hashtable)Ses sion["ReportParamsHa sh"]);
foreach (String keyParamName in reportParamsHas h.Keys)
{
Utilities.SetPa ram(crReportDoc ument, keyParamName, reportParamsHas h[keyParamName].ToString());
}
// export report
Utilities.Expor tToPDF(crReport Document, Server.MapPath( fileName));

// function that sets report parameters values
public static void SetParam( ReportDocument crReportDocumen t, string ParamName, object ParamValue)
{
//set the parameter value
crReportDocumen t.SetParameterV alue(ParamName, ParamValue);
}
// function to export the report
public static void ExportToPDF(Rep ortDocument Report, string file)
{ ExportToDisk(Re port, file, ExportFormatTyp e.PortableDocFo rmat);
}
private static void ExportToDisk(Re portDocument Report, string fileName,Export FormatType expFormat)
{
DiskFileDestina tionOptions diskOpts = ExportOptions.C reateDiskFileDe stinationOption s();

ExportOptions exportOpts = new ExportOptions() ;
exportOpts.Expo rtFormatType = expFormat;
exportOpts.Expo rtDestinationTy pe = ExportDestinati onType.DiskFile ;

diskOpts.DiskFi leName = fileName;
exportOpts.Expo rtDestinationOp tions = diskOpts;

Report.Export(e xportOpts);

}
