Assign a reportDocument object to a ReportViewer on run time and show it (ASPX,Crystal): update: visibility:hidden

Question

First at all, thanks in advance.

Well, I would like to show a report in the reportViewer Control from crystalReports.

I load manually the report (from an rpt file), it's in a ReportDocument object, I know is loaded without problems, because I can export to PDF/XLS and it works perfectly, but is not show it when I assign the report object as ReportSource of my ReportViewer control.

After load the report (at Init_Complete event) I'm doing this:

    crViewer.ReportSource = reportObject

But the web page doesn't show the report. Any idea ?

Thanks.

Update: for some reason the DIV for the reportViewer has this style:

visibility:hidden

I just need to know how to remove it or avoid it. (and of course I would like to know why that style is added).

Update 2: Besides the "visibility:hidden" the Crystal Image Handler isn't working, and all the report is in "html", I'm trying to use the report viewer control, to have a similar behavior to the reportViewer on WinForms, I'm trying to add the handler to the WebConfig but the tag isn't recognized.

Update 3: :( I couldn't add the handler anyone have a clue ?
