我想在代码级别呈现大型非图形报告(数千页)ReportViewer
,从 .rdlc 文件中省略只会阻塞浏览器的控件。当我测试呈现大约 2000 页的报告时,该Microsoft.Reporting.WebForms.LocalReport.Render
方法大约需要半小时才能完成,这被认为是糟糕的用户体验。
是否有任何技巧或替代解决方案来提高渲染性能:在代码中,重新设计 .rdlc 文件,或其他地方,例如,只是增加硬件?
示例代码:
LocalReport localReport = new LocalReport();
localReport.ReportPath = Server.MapPath("~/report.rdlc");
SetDataSources(ref localReport);
string reportType = "PDF";
string mimeType;
string encoding;
string fileNameExtension;
string deviceInfo =
"<DeviceInfo>" +
" <OutputFormat>PDF</OutputFormat>" +
" <PageWidth>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0in</MarginTop>" +
" <MarginLeft>0in</MarginLeft>" +
" <MarginRight>0in</MarginRight>" +
" <MarginBottom>0in</MarginBottom>" +
"</DeviceInfo>";
}
Warning[] warnings;
string[] streams;
byte[] renderedBytes;
//Render the report
renderedBytes = localReport.Render(
reportType,
deviceInfo,
out mimeType,
out encoding,
out fileNameExtension,
out streams,
out warnings);
非常感谢任何帮助,在此先感谢!
