Remarques

Vous utilisez généralement cette méthode si vous créez un concepteur pour ou System.Windows.Forms.DataGrid si vous créez votre propre contrôle incorporant le System.Windows.Forms.DataGrid. Vous pouvez utiliser la ShouldSerializeHeaderBackColor méthode pour déterminer si la valeur de la propriété a changé par rapport à sa valeur par défaut.
