Re: Deactivate event for pagepanel

I would have a boolean “Dirty”. It is set any time the user makes any change to any of the fields.

Then, in the close event or panel change event, check Dirty. If it is true, post a warning about saving the changes.

Simple. That is the way many applications do it.
