WebDataTree breaks CR reports
posted

Hi, I've encountered the problem that Infragistics's controls break CR (crystal report) reports.

When the control (WebDataTree) is present on the page, the  CrystalReportViewer doesn't build the report.

After two hours of investigation I can  provide some details and I hope somebody will explain why it happens and how we can solve or workaround this problem.

CR(Crystal Reports) renders script inside div that build the report (dynamically creates html).

The piece of page related to CR without WebDataTree on the page looks as following:

div id="ctl00_Content_reportViewer" script type="text/javascript"

script type="text/javascript"
  <!--
     bobj.crv.writeWidget( ...

But when  WebDataTree is present on the page it looks as following:

 div id="ctl00_Content_reportViewer"


  script type="text/javascript"
  <!--   bobj.crv.writeWidget( ...

That explains why the report is not built (because script is not even launched)

The question is why Infragistics's controls do this needless work? optimization by removing line carriages?

Please comment?
