Hi Mohamed Rasik,
have you tried to use “On leave” event in the checkbox properties? You can cancel changes there.
Hi Mohamed,
It sounds like you may not be committing the changed boolean value and/or you have the ‘refresh on show’ setting of your tab page set to ‘Yes’.
Changing either one of these settings should allow the data to be the same when you return the to tab page as when you left it.
Hope this is helpful,
