In out asp.net web page we are using column Extended property to get column property values. It is working fine but suddenly sometime it is throwing "Object reference not set to an instance of an object." error when it is trying to retry the information.
Without changing anythign if we do an iisreset on the web server it resolve the issue.
Any idea why this is keep happening and iisreset fix the issue? Any suggestion to fix this error?
Thanks in advance!
