When using reportviewer control on the web page. By default, the reportviewer has a fix width and height to 400px. But how do we change the value of width and height?

The answer I get from some forums, some said that set ZoomMode=”FullPage”, some recommended to set SizeToReportContent=”true”. Even with the 2 suggestions, I still cannot solve the problem.

The final answer I get it works is:

<rsweb:ReportViewer Width="100%" SizeToReportContent="true" AsyncRendering="false" … ></rsweb:ReportViewer>

AsyncRendering=”false” is the key. It will render inline HTML instead of using IFRAME. I have tested it from Internet Explorer 7.0, Firefix 3.0 and Google Chrome. :)

Be careful when setting the AsyncRendering property. Check out the explanation from http://msdn.microsoft.com/en-us/library/ms252090%28VS.80%29.aspx

Good luck and happy programming!
