Error Loading RadChart Image...

If you use cookieless session: The chart uses the Session to pass the image object to the image streamer. When the application is cookieless, the streamer cannot locate the image object in the Session. A suggested workaround is to disable the chart's session by setting the UseSession property of the control to false. In this case the chart image will be streamed through a file which will be temporarily written in the folder specified by the TempImageFolder of the chart. In order for the chart to work correctly you should grant write access for the APSNET user for this folder.
