Hello Sir,

I want to generate SSRS from Codes that is .rdlc extension files Please rectify my code I used in my page.

DataTable dt = new DataTable();
       dt=Tray.fillProjects();
            try
            {
                if (dt.Rows.Count > 0)
                {
                    ReportDocument rptdoc = new ReportDocument();
                    rptdoc.Load(Server.MapPath("~\\Reports\\Tremor.rdlc"));
                    rptdoc.SetDataSource(dt);
                 
                    crv.ReportSource = rptdoc;
                    crv.DataBind();

                    ExportOptions exportOpts1 = rptdoc.ExportOptions;
                    rptdoc.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
                    rptdoc.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
                    rptdoc.ExportOptions.DestinationOptions = new DiskFileDestinationOptions();
                    ((DiskFileDestinationOptions)rptdoc.ExportOptions.DestinationOptions).DiskFileName = Server.MapPath("Tremor.pdf");
                    rptdoc.Export();
                    rptdoc.Close();
                    rptdoc.Dispose();
                    Response.ClearContent();
                    Response.ClearHeaders();
                    Response.ContentType = "application/pdf";
                    Response.AppendHeader("Content-Disposition", "attachment; filename=Tremor.pdf");
                    Response.WriteFile("Tremor.pdf");
                    Response.Flush();
                    Response.Close();
                   System.IO.File.Delete(Server.MapPath("Tremor.pdf"));
                }
                else
                {
                    Page.ClientScript.RegisterStartupScript(this.GetType(),"Hello","javascript:alert('ok');",true);
                }
            }
            catch { }
    }

I debug this code When it reached to path that I have given above i.e. "~\\Reports\\Tremor.rdlc" it reaches to catch and throws exception Load Report failed
Please Guide me
