延迟使用asp.net中的报表查看器加载多个报表

Question

I am facing dramatic delay when loading SSRS reports in reportviewer dynamically in multiple popups. Once the first report is completely loaded, then only then next report starts processing even if I open the reports in parallel. So I have to wait for long time to load small report if long running report is opened before it. Its not loading in parallel. I have done some research on this and got to know from the below link that ReportViewer blocks the session for loading each report.

Can anyone help me on this. Is there any solution available for this?

I am using Microsoft.ReportViewer.WebForms Version=11.0.0.0, and Framework 4.5 with VS 2012. ReportViewer is in server mode. Please see the code below

reportViewer.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
reportViewer.ServerReport.ReportServerUrl = new Uri(ReportServer);
reportViewer.ServerReport.ReportPath = ReportPath.Trim();
reportViewer.SizeToReportContent = true;
reportViewer.ServerReport.Refresh();

Maybe breaking up the processing into multiple threads could be the answer. Create a list of the reports you'll have to get, then use the Parallel class like so...

Parallel.ForEach(reports => report
{
    // code for rendering your report
});

Likewise, you can also create an Action delegate for each report and simplify this down to...

Parallel.ForEach(reports => report.Invoke());
