Comment appliquer des styles à l'exécution dans Childwindow dans silverlight?

Question

Je ne suis pas en mesure d'appliquer le style à l'exécution sur la fenêtre enfant. J'ai créé deux styles un avec chrome et un sans chrome. Ce que je voulais faire est sur le mode plein écran mediaplayer désactiver le glissement de la fenêtre enfant et sur appuyer sur le bouton d'échappement (mode normal) permettre le glissement de la fenêtre enfant. Mon code ressemble à ceci:

void Content_FullScreenChanged(object sender, EventArgs e) 
{ 

     if (App.Current.Host.Content.IsFullScreen) 
     { 

      ObjChildMediaPlayer.Style = Application.Current.Resources["TestStyle"] as Style; 
     } 
     else 
     { 

      ObjChildMediaPlayer.Style = Application.Current.Resources["TestBasicStyle"] as Style;     

     } 

     ObjChildMediaPlayer.UpdateLayout(); 
    } 

Le traînage plein écran est invalidante, mais quand j'appuyez sur la touche d'échappement ne traîne pas. Je veux que la fenêtre enfant glisse en mode normal.
