Here is a stack trace from an error we got. There is no user code, so i suspect its an infragistics bug.
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.

When do you get this error. Could you provide steps to reproduce?
If you could upload sample application then it would be very helpful to understand the problem.
Well you see that is the problem - i dont have a clue how to reproduce it nor do i know what they were doing at the time unfortunately. It was an anonymous public user on our site.
All i have is this stack trace. Now, given that there is no user code leading up to this exception it makes me think that infagistics is not handling something properly internally.
It's entirely possible that there's something i can do to stop it, but i was more looking for someone to say "ah yeah, well looking at that stack trace here are some possibilities that might cause it... "
Can someone please shed some light on this problem. It looks like an infragistics bug.
