Response.Write("<h1>Error running report:</h1>");
Response.Write(eRunReport.ToString());
return;
}
//Buffer this page's output until the report output is ready.
Response.Buffer = true;
//Clear any part of this page that might have already been buffered for output.
Response.ClearContent();
//Clear any headers that might have already been buffered (such as the content
//type for an HTML page)
Response.ClearHeaders();
//Tell the browser and the "network" that the resulting data of this page should
//be cached since this could be a dynamic report that changes upon each request.
Response.Cache.SetCacheability(HttpCacheability.NoCache);
//Tell the browser this is an HTML document so it will use an appropriate viewer.
Response.ContentType = "text/html";
//Create the HTML export object
GrapeCity.ActiveReports.Export.Html.Section.HtmlExport htmlExport1 = new GrapeCity.ActiveReports.Export.Html.Section.HtmlExport();
//Export the report to HTML in this session's webcache
MyCustomHtmlOutputter outputter = new MyCustomHtmlOutputter(this.Context);
htmlExport1.Export(rpt.Document, outputter, "");
Response.Redirect("ReportOutput" + "/" + System.IO.Path.GetFileName(outputter.mainPage));
}
}
}

我看例子里面自己用程序生成了一个SectionReport,那如果是一个现成的带参数的pagereport又怎么处理呢？
还有，可不可以使用前台htmlExport然后进入打印页面？请技术支持的老师帮忙看看

您好，

您好，
RDL的思路是取到view，然后在直接操作打印。以下代码是基于您在帖子中提到的那篇博客的第二个例子进行功能的增加。
参考代码

var printBtn = '<span><input id="btnPrint" type="Button" value="Print" onclick="print()"/></span>';
$(document).ready(function () {
var selectedValue = $("#fldReportName").val();
if (selectedValue !== "") {
setTimeout(function () {
$("#ReportSelect").val(selectedValue);
}, 100);
}
var toolbar = $('#WebViewer1').find('.arvToolBar');
toolbar.append(reportSelect);
toolbar.append(exportSelect);
toolbar.append(printBtn);
var viewModel = GetViewModel("WebViewer1");
//Force a postback upon report selection
$("#ReportSelect").change(function (e, args) {
var reportName = this.value;
$("#fldReportName").val(reportName);
ForcePostBack();
this.value = $("#fldReportName").val();
});
function print() {
viewModel.Print();
};
