Windows Phone 7: Mettez en surbrillance l'élément de la liste sélectionnée

J'ai le code XAML suivant (zone de liste simple avec DataTemplate personnalisé). Je suis à essayer de comprendre comment mettre en surbrillance l'élément sélectionné (peut-être la couleur de fond du changement). Je me dis que je dois faire quelque chose avec des Styles dans Expression Blend, mais je ne suis pas tout à fait sûr où commencer...
Edit: Après un peu de jouer autour, j'ai maintenant ce (qui ne semble pas faire quoi que ce soit)
