Remarks
Whenever an edit operation is undone, the OnUndo event is fired. For example, if a feature is moved and Undo is called, the OnUndo is fired. This event is not fired when sketch operations are undone. For example, undoing the addition of a point to the edit sketch does not trigger the OnUndo event.
