XtraReports Web 查看器未加载参数弹出窗口

Question

因此，我们从保存的文件加载报告（这似乎不是执行操作的一般方法），但报告查看器拒绝初始化参数弹出窗口。卧槽！！！

这是代码：

protected void Page_Load(object sender, EventArgs e)
{
  string ReportName = Request["ReportName"];
  XtraReport newReport = CreateReportFromFile(ReportName);
  newReport.RequestParameters = true;
  ReportViewerControl1.Report = newReport;
}

private XtraReport CreateReportFromFile(string filePath)
{
  XtraReport report = new XtraReport();
  report = XtraReport.FromFile(filePath, true);
  return report;
}

仅在整页加载时执行此操作有帮助吗？

protected void Page_Load(object sender, EventArgs e)
{
  if( IsPostBack || Is IsCallBack )
  {
     return
  }

  string ReportName = Request["ReportName"];
  XtraReport newReport = CreateReportFromFile(ReportName);
  newReport.RequestParameters = true;
  ReportViewerControl1.Report = newReport;
}
