This property will tell you which page is active...

MyPageFrame.ActivePage

..and this method runs when the page has become active...

myPageFrame.mpage1.active()

...I've had to deal with the same problem, no GotFocus for the pages inside a pageframe. I've always manged to work around it by using a combination of these two things.
