C#

public ActionResult PatronLocationGraph()
{
  var rpt = new Services.Report.ReportService("PatronLocationGraph", null);
  var service = new PatronService(DataContext);

  //rpt.ReportDocument.ParameterFields.Add("Pie Chart for All Patrons By Location");
  //Here i am assigning it but i am getting missing parameter Exception
  var vms = service.GetGroupByLocation();
  rpt.ReportDocument.SetDataSource(vms);

  return ReturnPDF(rpt.GetPDFStream(), "PatronLocationGraph");
}

I have already added a text box in the Report Designer and in Field Explorer added New Parameter Named it "ReportLabel" and drag and drop this Parameter now i am assigning the Report Label but getting Missing Parameter Exception

Solution 1

set the parameter value after you set the datasource

C#

var vms = service.GetGroupByLocation();
rpt.ReportDocument.SetDataSource(vms);
rpt.ReportDocument.SetParameterValue("ReportName", "Report Name ....");
return ReturnPDF(rpt.GetPDFStream(), "PatronLocationGraph");

Dear DamithSL i am getting still the Same Exception.
Actually i have a Text Object in my Report and i want to put a string values from my Report Dynamically.
the main concern is with the report label in the designer not with the Real report name.
i have used this rpt.ReportDocument.SetParameterValue("ReportLabel","Pie Chart for All Patrons By Location");
