Hi,
I am writing a program that will export a report using a XML data source. I have designed a simple one table report to demonstrate this feature. Unfortunately, I cannot seem to figure out how to feed an updated XML file to the report at run-time. The following is a code snippet showing what I am trying to do.
// open the report file
ReportDocument rd = new ReportDocument();
rd.Load(@"Report1.rpt");
// read the xml data
DataSet reportData = new DataSet();
reportData.ReadXml(@"Report1.xml");
// update the report with the new data
rd.Database.Tables[0].SetDataSource(reportData.Tables[0]);
// export the report
ExportOptions CrExportOptions;
DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();
CrDiskFileDestinationOptions.DiskFileName = "Report1.pdf";
CrExportOptions = rd.ExportOptions;
{
CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
CrExportOptions.FormatOptions = CrFormatTypeOptions;
}
rd.Export();
System.Console.WriteLine("file exported");
The following exception is raised when execution reaches the Export() function.

Any insight on this error would be greatly appreciated.
Thx.
