Thank you for writing.
In Q3 2012 SP1 (version 2012.3.1211)
we introduced a reason for checking a check-box in the event arguments of the NodeCheckedChanged
event. However, this includes a breaking change as well listed in our release history. The signature of NodeCheckedChanged
event is changed to use TreeNodeCheckedEventArgs
I hope this information helps. Should you have further questions, I would be glad to help.
