           DataSet dssalaryDetails = getemplyeesalarydetail(id, pid);
           DataSet dsEmployeeCount = GetEmplyoeeCount(id, pid);
           int rowcount = dssalaryDetails.Tables[0].Rows.Count;
           if (rowcount == 0)
           {
               DataRow dr = dssalaryDetails.Tables[0].NewRow();
               dssalaryDetails.Tables[0].Rows.Add(dr);
           }
           else
           {
               Boolean salaried = false;
               foreach (DataRow dr in dssalaryDetails.Tables[0].Rows)
               {
                   if (dr["issalaried"].ToString() == "Y")
                   {
                       salaried = true;
                   }
               }
               if (salaried == false)
               {
                   issalaried = "N";
               }
               else
               {
                   issalaried = "Y";
               }
           }
           ReportDataSource datasource = new ReportDataSource("DS1", DsRep.Tables[0]);
           ReportDataSource datasourcefamily = new ReportDataSource("DS2", dssalaryDetails.Tables[0]);
           ReportDataSource datasourcecount = new ReportDataSource("DS3", dsEmployeeCount.Tables[0]);
           ReportParameter[] Param = new ReportParameter[1];
           Param[0] = new ReportParameter("Param_IsSalaried", issalaried);
           Warning[] warnings;
           string[] streamIds;
           string mimeType = string.Empty;
           string encoding = string.Empty;
           string extension = string.Empty;
           // Setup the report viewer object and get the array of bytes
           ReportViewer viewer = new ReportViewer();
           viewer.ProcessingMode = ProcessingMode.Local;
           viewer.LocalReport.ReportPath = Server.MapPath("~\\Employee.rdlc");
           //Datasource
           viewer.LocalReport.DataSources.Add(datasource);
           viewer.LocalReport.SetParameters(Param);
           viewer.LocalReport.EnableExternalImages = true;
           byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);

           // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
           Response.Buffer = true;
           Response.Clear();
           Response.ContentType = mimeType;
           Response.AddHeader("content-disposition", "attachment; filename=" + "Employee" + "." + extension);
           Response.BinaryWrite(bytes); // create the file
           Response.Flush(); // send it to the client to download
           //Page settings for PDF File.

       }
