I am not sure if I understand completely the requirements of your scenario, but you can handle the PreviewTileStateChanged
event to stop the maximization of an item. Since the PreviewTileStateChangedEventArgs
will give you access to the tile which state is changing, you can change the tile's BorderBrush
Please have a look at the attached sample and let me know if it helps. I hope it will get you started on your task.
All the best,
