Hi,

Thank you for your post. I have tested the behavior that you had reported and it seems that the ‘Record’ of the ‘RecordExpandingEventArgs’ return the expanded record(see the attached debugging.png). I have just clicked the expanding indicator and the record is not active(‘IsActive’ is “false”). If you select the record and after that click on the expanding indicator, the ‘Record’ will be active (‘IsActive’ is “true”).

Let me know, if I can assist you with something else on this matter.
