    try
    {
        rpt.Run(false);
    }
    catch (Exception eRunReport)
    {
        // Failure running report, just report the error to the user:
        Response.Clear();
        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 this resulting data of this page should be 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 html = new GrapeCity.ActiveReports.Export.Html.Section.HtmlExport();
    // Export the report to HTML in this session's webcache:
    //this.htmlExport1.Export(rpt.Document, GrapeCity.ActiveReports.Web
    MyCustomHtmlOutputter outputter = new MyCustomHtmlOutputter(this.Context);
    this.htmlExport1.Export(rpt.Document, outputter, "");
    Response.Redirect("ReportOutput" + "/" + System.IO.Path.GetFileName(outputter.mainPage));
}
