ASP.NET MVC 在经过长时间的发展之后，在生产环境中逐渐得到大家的认可，特别是 ASP.NET MVC 4 发布之后，不少新系统选择基于该技术进行研发。本文主要介绍 ActiveReports在 ASP.NET MVC 中的导出的使用方法。
1.基于WebViewer的HTMLViewer模式下的报表打印和导出
a) 在WebViewer中添加打印和导出按钮
第一步，在 VS 中创建一个 ASP.NET MVC 的应用程序
详细可以参考以下博客
ASP.NET MVC 4 中使用 ActiveReports 报表
第二步，添加导出相关的功能
导出excel的代码：
public ActionResult ExportExcel()
{
GrapeCity.ActiveReports.PageReport _reportDef =
new GrapeCity.ActiveReports.PageReport(new FileInfo(Server.MapPath("/Reports/rptInvoice1.rdlx")));
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.Xlsx;
excelSetting.MultiSheet = true;
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());
outputProvider.GetPrimaryStream().OpenStream().CopyTo(ms);
return File(ms.ToArray(), "application/vnd.ms-excel", Url.Encode("export.xlsx"));
}
导出pdf的代码
public ActionResult ExportPDF()
{
GrapeCity.ActiveReports.PageReport _reportDef =
new GrapeCity.ActiveReports.PageReport(new FileInfo(Server.MapPath("/Reports/rptInvoice1.rdlx")));
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.Pdf.Page.Settings pdfSetting = new
GrapeCity.ActiveReports.Export.Pdf.Page.Settings();
GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = pdfSetting;
//Set the rendering extension and render the report.
GrapeCity.ActiveReports.Export.Pdf.Page.PdfRenderingExtension pdfRenderingExtension =
new GrapeCity.ActiveReports.Export.Pdf.Page.PdfRenderingExtension();
return File(ms.ToArray(), "application/pdf", Url.Encode("export.pdf"));
GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider outputProvider =
new GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider();
_reportRuntime.Render(pdfRenderingExtension, outputProvider, pdfSetting);
outputProvider.GetPrimaryStream().OpenStream().CopyTo(ms);
}
第三步，在显示的页面增加导出按钮
<ol class="round">
<li class="one">@Html.ActionLink("导出Excel", "ExportExcel", "Home")</li>
<li class="two">@Html.ActionLink("导出PDF", "ExportPDF", "Home")</li>
</ol>

b) 通过前端JS操作ViewModel实现代码
在页面添加相应的JS代码
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script language="javascript" type="text/javascript">
var exportSelect = '<select id="ExportSelect" style="width:80px">
<option selected disabled>Export</option><option value="PDF" style="background: url(images/pdf.png)
right no-repeat; width: 50px">PDF</option><option value="Excel"
style="background: url(images/Excel.gif) right no-repeat; width: 50px">Excel</option></select>';
$(document).ready(function () {
var toolbar = $('#1_WebViewer1').find('.arvToolBar');
toolbar.append(exportSelect);
toolbar.append("<span><input id='btnPrint' type='Button' value='Print'/></span>");
var viewModel = GetViewModel("1_WebViewer1");
//Check the selected value in DropDown and Export
$("#btnPrint").click(function () {
if (viewModel.PageLoaded()) {
viewModel.Print();
}
});
$("#ExportSelect").change(function (e, args) {
var valueSelected = this.value;
if (viewModel.PageLoaded()) {
switch (valueSelected) {
case "PDF":
viewModel.Export(ExportType.Pdf, function (uri) {
window.location = uri;
}, true);
break;
case "Excel":
viewModel.Export(ExportType.Xls, function (uri) {
window.location = uri;
}, true);
break;
}
}
});
});
</script>

2. 基于WebViewer的FlahViewer模式下的报表打印和导出
使用FlashViewer
<ActiveReportsWeb:WebViewer ID="WebViewer1" runat="server" height="600px" width="960px"
ViewerType="FlashViewer" FlashViewerOptions-ShowSplitter="false"
>
</ActiveReportsWeb:WebViewer>
添加对应的路由
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("ActiveReports.ReportService.asmx/{*pathInfo}");
routes.IgnoreRoute("Grapecity.ActiveReports.Flash.v9.swf");

3.基于HTML5Viewer的报表打印和出导
使用HTML5
var viewer = GrapeCity.ActiveReports.Viewer({
element: '#viewerContainer',
reportService: {
url: '/ActiveReports.ReportService.asmx'
},
uiType: 'desktop',
reportLoaded : function () {
reportsButtons.prop('disabled', false);
}
});
