Hi,

Thank you for your reply; it's exactly what I'm looking for: "Resources.Customizer" by control

As an example for other, like me, how do not find it: (translation in French)

if (Application.CurrentCulture.TwoLetterISOLanguageName.ToLower() == "fr")
{
Infragistics.Win.UltraWinToolbars.Resources.Customizer.SetCustomizedString("MinimizeRibbon", "Réduire le ruba&n");
Infragistics.Win.UltraWinToolbars.Resources.Customizer.SetCustomizedString("QuickAccessToolbarBelowRibbon", "Afficher la barre d'outils Acc&ès rapide sous le ruban");
Infragistics.Win.UltraWinToolbars.Resources.Customizer.SetCustomizedString("QuickAccessToolbarAboveRibbon", "Afficher la barre d'outils Accès ra&pide au-dessus du ruban");
}
else
{
Infragistics.Win.UltraWinToolbars.Resources.Customizer.ResetAllCustomizedStrings();
}
