ReportDocument.Export() raises "Missing Parameter Values" exception

Question

Hi
Recently I encountered a question about SAP Crystal Report that I have a rpt file with several sub reports and I am required to make the data source to be XML with http/https URLs. I created different .NET pages which returns XML stream as data source for both main report and sub reports in my rpt file, and also created a sub report links which pass dynamic parameters from main report to the sub reports, everything worked fine when I entered the necessary parameters only for the main report in the design tool, both the main report and sub reports displayed perfectly.
But it did not work in my .NET application which export the reports to PDFs, I referenced “CrystalDecisions.CrystalReports.Engine” and some other necessary DLLs into my project, and then I created an instance of ReportDocument, loaded the rpt file, set parameters which used in the main report, set connection info, and at last when I export the report it throw out an exception with “Missing Parameter Values” error message, even though I removed the sub report links which pass parameters from main report, the exception still occurred, but when I removed all the sub reports, and only export the main report it worked!!
Here is a result of my attempts:
Main Report
Sub Report
Result
1
With XML data source
No report
Works fine with dynamic parameters set to the http/https url which returns an xml results
2
With XML data source
Pass a static value and print it on the report
Works fine.
3
With XML data source
Create a SQL command WITHOUT any parameters passed from main report
Works fine
4
With XML data source
Create a SQL command WITH a dynamic parameter passed from main report
Works fine
5
With XML data source
Create a xml data source WITHOUT any parameters passed from main report
Failed with "Missing Parameter Values"
6
With XML data source
Create a xml data source WITH a dynamic parameter passed from main report
Failed with "Missing Parameter Values"
I am confused about this issue for a few days, is there any ideas or helps? many thanks!

OK:
We upgraded to CR 13.0.2000.0 and Visual Studio 2012 and .Net Framework 4.5.
Problem still happens.
When we display the report in the designer, the url has parameters.  Here are the IIS log entries:
2014-05-01 18:24:56 192.168.251.10 GET /quotit/apps/leadspro/CrystalServiceGateway_test.aspx @IFPPSID=1899582751211388&@styleColorScheme=10511658/13343077/10511658/13343077/16777215/15720656/16777215/15720656/24831/13426687|10511658/16777215/16777215/16777215/0/0/0/0/0/0 80 - 10.16.26.44 Java/1.6.0_37 200 0 0 959

When we use the crystaldecisions.crystalreports.engine, no parameters are passed.  Here are the IIS log entries:
2014-05-01 18:22:28 192.168.251.10 GET /quotit/apps/leadspro/CrystalServiceGateway_test2.aspx - 80 - 10.16.26.44 Java/1.7.0_45 200 0 0 58
2014-05-01 18:22:28 192.168.251.10 GET /quotit/apps/leadspro/CrystalServiceGateway_test.aspx - 80 - 10.16.26.44 Java/1.7.0_45 200 0 0 115
I cannot attach the rpt file here.  If you need it, please let me know how to get it to you.  I am attaching a screenshot of the datasource location.  I am pasting in the striped down .NET code.  Any help or pointers would be greatly appreciated.
Thanks,
Tom
