How to Pass parameters value in SSRS rdl through .NET

Hello experts,
I m calling one SSRS report which is on another server Url (http://10.32.149.149/reportserver) in my .NET application
It works fine when i call from Reportviewer.aspx directly without passing any parameters

But when i call this report by passing parameters from .NET, it gives error

 ReportViewer1.ProcessingMode = ProcessingMode.Remote;
            IReportServerCredentials irsc = new CustomReportCredentials("manoj", "password", "domain");
            ReportViewer1.ServerReport.ReportServerCredentials = irsc;


        
            
            ReportViewer1.ServerReport.ReportPath = "/ReportRDL/RptStateInfo";
            ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://10.32.149.149/reportserver");

            ReportViewer1.ShowParameterPrompts = false;
            ReportParameter[] parm = new ReportParameter[7];
            parm[0] = new ReportParameter("P_STATEID_V", "12");
            parm[1] = new ReportParameter("P_DISTRICTID_V", "245");
            parm[2] = new ReportParameter("P_SUBDISTRICTID_V", string.Empty);
            parm[3] = new ReportParameter("P_HEALTHFACILITYID", string.Empty);
            parm[4] = new ReportParameter("P_FORMID_N", "34");
            parm[5] = new ReportParameter("P_FINYEARID_N", "16");
            parm[6] = new ReportParameter("P_EntryLEvel", "D");

            this.ReportViewer1.LocalReport.SetParameters(parm);
           ReportViewer1.ServerReport.Refresh();

And error is The source of the report definition has not been specified

Please suggest any solution for it
