No response when binding dataset to the subreport

Question

Hi,
Environment:
OS : Windows 7
Crystal report for VS2010 (13.0.2)
Visual Studio 2010 ( using WPF)
How to bind the loaded dataset to the sub report. I tired in my code the following:
try{
rpt.OpenSubreport("SubreportName").SetDataSource(ds);
Catch(Exception ex)
  MessageBox.WPFMessageBox.Show("error message " + ex.Message);
While debugging dataset ds is having recordset loaded. When I bind using the above code snippet, no response or some getting error as "load report failed."
Please help me ASAP.
Thanks & Regards,
Mani G.S.

Hello,
You can't simply open the subreport....
Here's code on how to:
public Form1()
     // Required for Windows Form Designer support
     InitializeComponent();
     // TODO: Add any constructor code after InitializeComponent call
     //Create an instance of the strongly-typed MAIN report object
     crReportDocument = new MainReport();
     //Get all the sections in the report
     crSections = crReportDocument.ReportDefinition.Sections;
     //Loop through each section of the report
     SubNames = "";
     foreach(Section crSection in crSections)
          //Get all the report objects from each section
          crReportObjects = crSection.ReportObjects;
          //Loop through each report object
          foreach(ReportObject crReportObject in crReportObjects)
               //Check to see if the report object is a subreport
               if (crReportObject.Kind == ReportObjectKind.SubreportObject)
                    //Found the subreport 
                    //Get the actual subreport object
                    crSubreportObject = (SubreportObject)crReportObject;
                    //Get the subreport as a regular report object 
                    //OpenSubreport returns the subreport object as a report
                    crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName);
                    //Display the name of the subreport
                    if (SubNames.Length > 0) SubNames += ", ";
                    SubNames = crSubreportDocument.Name;
               }//Go to the next report object
     }//Go to the next section
     MessageBox.Show("Subreport Names: " + SubNames);
     //Set the viewer to the report object to be previewed
     crystalReportViewer1.ReportSource = crReportDocument;
