Hi,

Most of the events are raised only in response to users actions. The Deleted event is one of the few exceptions - it is raised every time an item is deleted - never mind whether it is programmatically, interactively, or internally by Flowchart.NET. If you need to detect that an item is added due to undo/redo, you will need to handle the ActionUndone and ActionRedone events and check the type of the action that is passed as an argument to these events.

I hope that helps,
Stoyan
