different buttons for different pages

As far as I've understand from your problem, you can do one thing. Just make two sets of the buttons. One set with highlighted color and the other set with the grayed out color. Initially, uncheck the Initially visible property of the highlighted set of buttons. Make sure that your highlighted buttons are created over the grayed buttons. Now execute an action in each page on the On Show event to display the respective highlighted button of that page.I hope I'm able to provide you the right suggestion to your query.
