Hi...<BR><BR>I am making use of crystal reports. I created a report from a asp.net dataset file(.xsd). In my aspx I added a crystalreportviewer component and onload I set the crystalreportviewer&#039;s report source to the report and setDataSource of the report object to a Dataset.<BR><BR>All this is fine. If I leave my report blank then a blank report is displayed. But if I add any dataset field to the report then the following error is displayed.<BR><BR>Server Error in &#039;/media&#039; Application.<BR>--------------------------------------------------------------------------------<BR><BR>Query Engine Error: &#039;C:WINNTTEMP emp_f2f48082-0268-4727-9823-d073c008dbca.rpt&#039; <BR>Description: An unhandled exception occurred during the execution of the current web request.
