必须在配置中注册 WebResource.axd 处理程序才能处理此请求 RDLC 报告运行时

问题描述

我知道这个问题之前已经讨论过了。但在我的情况下它是不同的。 每当我尝试显示 .rdlc 报告时，它都会给我一个例外。我不明白是什么原因。 我试图更改我的配置文件中的一些引用，但仍未解决。我错过了什么吗？

reportViewer1.LocalReport.EnableExternalImages = true;
ReportDataSource rds = new ReportDataSource("DataSet1",dtData);
reportViewer1.ProcessingMode = ProcessingMode.Local;
reportViewer1.LocalReport.DataSources.Add(rds);
reportViewer1.LocalReport.ReportPath = report_Path;

if (multipleDatasetSelected && SubReportSelected)
    reportViewer1.LocalReport.SubreportProcessing += LocalReport_SubreportProcessing;

if (lstParan.Count > 0)
{
   foreach (string key in lstParan.Keys)
   {
      reportViewer1.LocalReport.SetParameters(new ReportParameter(key,lstParan[key]));
    }
}

this.reportViewer1.LocalReport.Refresh(); 

每当最后一行运行this.reportViewer1.LocalReport.Refresh();。我在报告查看器中遇到异常 =>
