报表导出

在WebCharReport.aspx里的EXCEL导出报表时报
，是不是我后台数据绑定的问题，请求解

请查看以下代码，添加了 _reportRuntime.LocateDataSource += new GrapeCity.ActiveReports.LocateDataSourceEventHandler(Document_LocateDataSource);

1.     protected void btnExcel_Click(object sender, EventArgs e)
   
2.     {
   
3.         string path = Server.MapPath("rptSalesByCategory.rdlx");
   
4.         GrapeCity.ActiveReports.PageReport rptPreview = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(path));
   
5.         WebViewer1.LocateDataSource += new GrapeCity.ActiveReports.LocateDataSourceEventHandler(Document_LocateDataSource);
   
6.             
   
7.         WebViewer1.Report = rptPreview;
   
8.         GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(rptPreview);
   
9.         _reportRuntime.LocateDataSource += new GrapeCity.ActiveReports.LocateDataSourceEventHandler(Document_LocateDataSource);
   
10. 
    
11.         GrapeCity.ActiveReports.Export.Excel.Section.XlsExport XlsExport1 = new GrapeCity.ActiveReports.Export.Excel.Section.XlsExport();
    
12. 
    
13.         System.IO.MemoryStream ms = new System.IO.MemoryStream();
    
14.         XlsExport1.FileFormat = GrapeCity.ActiveReports.Export.Excel.Section.FileFormat.Xlsx;
    
15.         XlsExport1.Export(_reportRuntime, ms);
    
16. 
    
17.         Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    
18.         Response.AddHeader("content-disposition", Server.UrlPathEncode("attachment;filename=客户订单.xlsx"));
    
19.         Response.BinaryWrite(ms.ToArray());
    
20.         Response.End();
    
21.     }

假如在SectionReport这种报表里实现excel，word,pdf等格式导出的话那么要怎样绑定数据呢

区域报表数据源是通过 SectionReports1.DataSource 来实现数据绑定的。
