free lightweight report component for asp.net

I am quite new to asp and my question is: what free lightweight report component for asp.net are out there. Crystal rep开发者_运维知识库ort is not welcomed and we would like to avoid using heavy ObjectDatasource. What sould I learn first (may be asp page life cycle) and what are time proven free analog of ReportViewer for asp is out there.

Thanks in advance.

I have no personal experience with it, but you may look at Jasper Reports.net. I have successfully used the Jasper Reports java, which is very good. See
