关于套打，我知道怎么打印一个，预览的时候也只出现一个，但是我希望能够选择多条数据的时候，批量套打多条记录，也就是一条记录是一个页面。这个怎么实现啊下面是我的前端方法。

$(function () {
var reportId = request('reportId');
reportId = decodeURI(reportId);
var viewer = GrapeCity.ActiveReports.Viewer(
      {
         element: '#viewerContainer',
         report: {
            id: 'Modules/ActiveReports/HCtotalbyCategory.rdlx?id='11111'',
         },
         reportService: {
            url: '/ActiveReports.ReportService.asmx'
         },
         uiType: 'desktop'
      });
});

后台是这样

protected override object OnCreateReportHandler(string id)
      {
         string[] report = reportPath.Split('|');
         if (report.Length > 1)
         {
            reportPath = report[0];
            id = report[1];
         }
         definition1 = (PageReport)base.OnCreateReportHandler(reportPath);
         _pageDocument = new PageDocument(definition1);

            definition1.Document.LocateDataSource += new LocateDataSourceEventHandler(DataSource1);

         return definition1;
      }
      private void DataSource1(object sender, LocateDataSourceEventArgs args)
      {

         if (args.DataSet.Query.DataSourceName == "DataSource1")
         {
            if (args.DataSet.Name == "DataSet1")
            {

                  args.Data = GetDataSource(id);
            }

         }

      }

private DataTable GetDataSource(int id)
      {
         string connStr = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", Server.MapPath("/NWind_CHS.mdb"));
         string productSql = string.Format("SELECT * From 入库单 where 入库单ID = '" + id + "' order by ID ");
         DataLayer dl = new DataLayer(connStr, productSql);
         return dl.DataSetData.Tables["Products"];
      }

这样只能获得一个，我想要打印多张怎么改，求教
