I am also getting this type of issues but when i change the code to the following way it works fine.

this.report .LocalReport.ReportPath = "";
this.report .LocalReport.DataSources.Clear();
this.report .LocalReport.Refresh();
this.report .LocalReport.ReportPath = Server.MapPath("~/Reports/RecieptVoucherForStudent.rdlc");
ReportDataSource rptUserHeader = new Microsoft.Reporting.WebForms.ReportDataSource("DatasetName", dt);
this.report.LocalReport.DataSources.Add(rptUserHeader);
this.report.LocalReport.Refresh();

DatasetName- The Dataset is created in the App_Code Dataset
