Hi All,

I'm developing an AJAX-enabled web application. In one of my pages, I try to export a report to PDF format. I don't show the report on the web page, I just export it directly to be printed.

However, if I do this directly from my page, it won't work because this is not compatible with AJAX. So, I made the print button to open a pop-up window (by using the window.open javascript function and calling it from server side.)

And at the page load of the pop up page, I export the report. However, the problem that happens is that the pop up page closes immediately after being opened. I tried to disable the pop up blocker in my IE8 but this didn't work.

Any help is really appreciated.

Thanks suthish,

I think we cant prog disable pop up blockers

I don't mean to disable the pop-up blocker programatically. As I said in my previous post. I did disable the pop-up blocker manually. However, the problem continued to occur. So, it seems that it's not a matter of pop-up blocking.

Any ideas on why this is happening?

Thanks in advance,

Hi suthish,

I debugged the pop up page load, but there's no errors or exceptions that appear at all. It goes fine through all the lines until the last one, and then it closes it gives that sound like if a pop-up is caught by the browser.

Here's how I export my report:

// Read query string

        CrystalDecisions.CrystalReports.Engine.ReportDocument doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        string path = "report path";
        doc.Load(path);

        doc.SetDatabaseLogon("db user name", "db password");
        doc.SetParameterValue("parameter name", parameter_value);


        doc.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, true, "ExportedReport");

Please note that when I place a button inside the pop up page and let the user click it to export the report instead of exporting it at page load, it works fine. However, I think that letting it be exorted at page load is more user friendly.

Thanks
