Erreur - Vous ne trouvez pas ressource nommée « ComboBoxFocusVisual »

Question

Je suis en train d'ajouter un dictionnaire de ressources pour ComboBox et je reçois cette erreur après avoir appliqué le stlye (le style ne fonctionne pas/spectacle):

Une exception non gérée de type 'System.Windows.Markup.XamlParseException' a eu lieu dans PresentationFramework.dll

informations complémentaires: Vous ne trouvez pas ressource nommée 'ComboBoxFocusVisual'. Les noms de ressources sont sensibles à la casse.

Qu'est-ce qui aurait pu ne pas fonctionner? J'ai essayé de recharger le projet et de le construire.

Ceci est mon code:

Ajouter le style manquant suivant au-dessus de votre style ComboBox:

<Style x:Key="FocusVisual"> 
    <Setter Property="Control.Template"> 
     <Setter.Value> 
      <ControlTemplate> 
       <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

Vous aurez bien sûr besoin de définir la « ButtonNormalBackground "," ButtonNormalBorder "et toutes les autres ressources que vous référencez également. Vous devriez être en mesure de les obtenir du même endroit où vous avez obtenu le style ...
