This issue is a common one who starts working on Crystal Reports with Dataset (.Net)

Ill show a sample code snippet where you can generate this issue.

                 ReportDocument report = new ReportDocument();    

                 BAgent bAgent = new BAgent();
                 DataSet dsStatus = new DataSet();
                 dsStatus = bAgent.GetStatus();

                 string reportPath = Server.MapPath("/Agent/Reports/GetStatusRpt.rpt");  
                 report.Load(reportPath);

                 report.SetDataSource(dsStatus);// this is the line cause for this issue
                CrystalReportViewer1.ReportSource = report;  
                 CrystalReportViewer1.DataBind();  
                 CrystalReportViewer1.RefreshReport(); 

Here is the solution, use the datset table instead of the dataset

                 ReportDocument report = new ReportDocument();    

                 BAgent bAgent = new BAgent();
                 DataSet dsStatus = new DataSet();
                 dsStatus = bAgent.GetStatus();

                 string reportPath = Server.MapPath("/Agent/Reports/GetStatusRpt.rpt");  
                 report.Load(reportPath);

                 report.SetDataSource(dsStatus.Tables[0]); 
                 CrystalReportViewer1.ReportSource = report;  
                 CrystalReportViewer1.DataBind();  
                 CrystalReportViewer1.RefreshReport(); 

Hope you got rid from this issue. Enjoy coding.
