Exemples
Cet exemple montre comment utiliser un Style objet pour modifier les propriétés de style de plusieurs contrôles à la fois. Chaque fois que l’une Style des valeurs de propriété change, chaque contrôle doit appeler sa ApplyStyle méthode. Notez que tous les contrôles inclus ne prennent pas en charge toutes les propriétés présentées. Si un contrôle ne prend pas en charge une propriété particulière, l’apparence du contrôle ne change pas lorsque la valeur de la propriété est modifiée.
Notes
L’exemple de code suivant utilise le modèle de code à fichier unique et peut ne pas fonctionner correctement s’il est copié directement dans un fichier code-behind. Cet exemple de code doit être copié dans un fichier texte vide qui a une extension .aspx. Pour plus d’informations sur le modèle de code Web Forms, consultez ASP.NET Web Forms Modèle de code de page.

Remarques
Utilisez la ForeColor propriété pour spécifier la couleur de premier plan du contrôle serveur Web. La couleur de premier plan est généralement la couleur du texte. Cette propriété s’affiche sur les navigateurs antérieurs à Microsoft Internet Explorer version 4 pour tous les contrôles, à l’exception de Image, AdRotatorHyperLink et LinkButton.
Notes
Sur les navigateurs qui ne prennent pas en charge les styles, cette propriété est rendue en tant qu’élément FONT.
