Sur la sélection Tabitem, Style ne fonctionne pas

Question

J'ai créé un style pour Tab Control et TabItem dans un fichier xaml.

Lorsque TabControl est en cours de chargement première fois sur la fenêtre, son style d'application comme il le voulait. Mais lorsque je sélectionne un autre tabItem, son style de propriété IsSelection n'est pas exécuté.

Lors de la sélection : Trajectoire de tracé = "bleu" et arrière-plan de Bd = "jaune".

S'il vous plaît, aidez-moi à trier ce numéro.

Merci à l'avance.
