Remarques
Utilisez la MergeWith méthode pour combiner les propriétés de style de l’objet spécifié Style avec cette instance de la DataGridPagerStyle classe. Si une propriété de cette instance est déjà définie sur une valeur, la propriété n’est pas modifiée. Si une propriété n’est pas définie, cette méthode définit cette propriété avec la valeur de la propriété correspondante de l’objet Style .
