ActiveReports 支持多种格式的报表导出,包括PDF、Excel、Word、RTF、HTML、Text、TIFF以及其它图片格式。在最新的ActiveReports 9 中提供了新的导出方法,使用Render进行导出。本文主要介绍如何使用新的Render方法进行Excel的导出。

在AR中报表类型分为区域报表,页面报表和RDL报表。在以下两个方法中,导出的适用报表的类型稍有差别。

1.使用XlsExport导出

以导出excel格式为例,XlsExport能够支持所有的报表类型

            GrapeCity.ActiveReports.PageReport _reportDef = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("/Reports/" + report + ".rdlx")));
            _reportDef.Report.DataSources[0].DataSourceReference = "";
            _reportDef.Report.DataSources[0].ConnectionProperties.DataProvider = "OLEDB";
            _reportDef.Report.DataSources[0].ConnectionProperties.ConnectString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", Server.MapPath("/Data/NWind_CHS.mdb"));
            GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(_reportDef);
            
            GrapeCity.ActiveReports.Export.Excel.Section.XlsExport XlsExport1 = new GrapeCity.ActiveReports.Export.Excel.Section.XlsExport();
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            XlsExport1.FileFormat = GrapeCity.ActiveReports.Export.Excel.Section.FileFormat.Xlsx;
            XlsExport1.Export(_reportRuntime, ms);
            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.AddHeader("content-disposition", Server.UrlPathEncode("attachment;filename=MyExport.xlsx"));
            Response.BinaryWrite(ms.ToArray());
            Response.End();

 

2.使用Render的方式导出

Render只能用来导出页面报表和RDL报表,但是对性能和样式都有很大的提升

            // Provide the page report you want to render.
            GrapeCity.ActiveReports.PageReport _reportDef = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("/Reports/" + report + ".rdlx")));
            _reportDef.Report.DataSources[0].DataSourceReference = "";
            _reportDef.Report.DataSources[0].ConnectionProperties.DataProvider = "OLEDB";
            _reportDef.Report.DataSources[0].ConnectionProperties.ConnectString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", Server.MapPath("/Data/NWind_CHS.mdb"));
            GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(_reportDef);
            // Create an output directory
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            // Provide settings for your rendering output.
            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings
            excelSetting = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings();
            excelSetting.FileFormat = GrapeCity.ActiveReports.Export.Excel.Page.FileFormat.Xls;
            //excelSetting.MultiSheet = false;
            GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = excelSetting;
            //Set the rendering extension and render the report.
            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension
            excelRenderingExtension = new
            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension();
            GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider();
            _reportRuntime.Render(excelRenderingExtension, outputProvider, excelSetting.GetSettings());
            Response.ContentType = "application/vnd.ms-excel";
            Response.AddHeader("content-disposition", "inline;filename=MyExport.xls");
            outputProvider.GetPrimaryStream().OpenStream().CopyTo(ms);
            Response.BinaryWrite(ms.ToArray());
            Response.End();
