Error When Dragging Group Items...
posted
I get the following error when I try to drag group items off the explore bar
onto the form to the right. The exploer bar is part of the parent MDI
container.

This is the error:

An Unhandled Exception of type System.NullReferenceExceptions occured in
Infragistics2.Win.UltraWinExplorerBar.v7.3.dll

Additional Information:
Object reference not set to an instance of an object.

Can someone help me with preventing the application from crashing when this
occurs?

    There is very little information to go on here, but there was a bug a while back which caused the control's ItemFromPoint method to throw a null reference exception when there was no item at the specified point; if you are using this method in the release version, that might explain the problem. This bug has since been fixed; if you download the latest version, and the problem persists, you should log an incident with Developer Support so that you can provide the details necessary in order to reproduce the issue.
