this .reportViewer1.RefreshReport();
}
private   void  PassReport()

ReportParameter[] allPar =  new  ReportParameter[3];  // create parameters array
ReportParameter parSum =  new  ReportParameter( "Sum" ,  "195" );
ReportParameter parDiscount =  new  ReportParameter( "discount" ,  "19" );
ReportParameter parTotal =  new  ReportParameter( "total" ,  "176" );
allPar[0] = parSum;  //assign parameters to parameter array
allPar[1] = parDiscount;
allPar[2] = parTotal;
reportViewer1.LocalReport.SetParameters(allPar);  // set parameter array
}

Hi Umut,   You can pass parameter like,   ReportDocument reportdocument =  new  ReportDocument();   reportdocument.Load(Server.MapPath( "CrystalReport.rpt" ));
reportdocument.SetParameterValue( " Sum " , " 195 "); reportdocument.SetParameterValue( " discount " , " 19 ");  reportdocument.SetParameterValue( " total " , " 176 ");    CrystalReportViewer1.ReportSource = reportdocument;

You have passed more parameters than the defined in the reportviewer at the design time. As I can see in your screen shot only one parameter you have defined but you are passing 3 parameters in code behind.
