Jeffrey,
You can use a custom Page class with code in it's Activate/Deactivate to set the BackColor. If you don't want to go through the effort of creating a Page class you can put the code on the pages of this specific PageFrame.
>I am sooo sorr for being vague. My apologies. I tend to multi-task too much (physically). There is a 6 page pageframe that my users are using. I want to change the background color of the active page only to become light gray, which is the defaul page background (i think). Once the user selects page 2 of 6, then the first page's background is changed and then page 2 backgroung is changed to the light gray color and all others are dark gray. Hope this clear things up or are they cloudier!??
