The PAGE_CHANGED events are sent after the page has been changed and the program cannot veto it any more, it just informs it about the page change. To summarize, if the program is interested in validating the page values before allowing the user to change it, it should process the PAGE_CHANGING event, otherwise PAGE_CHANGED is probably enough.
