Sub Report Parameter in RDLC

See more:

RDLC

void SubreportProcessingEventHandler(object sender, SubreportProcessingEventArgs e)
       {

           string Id = e.Parameters[0].Values[0].ToString();

           List<ReportParameter> parametersSub = new List<ReportParameter>();
           parametersSub.Add(new ReportParameter("Id", Id));


           ReportViewer1.LocalReport.EnableExternalImages = true;
           ReportViewer1.LocalReport.ReportPath = Server.MapPath("SubReportName.rdlc");
           ReportViewer1.LocalReport.SetParameters(parametersSub);
           ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("dsSubReport", this.SqlDataSource));

        }

I am using above code for passing parameter from main report to sub report but this does not works and provides me error. Please advise.
