Question Tableau et ListBox

Tu peux t'inspirer de l'exemple suivant qui utilise le databinding de .NET. Cela permet de lier une collection à un composant hébergeant une liste et d'éviter une duplication des données (liste d'origine et liste du composant)

et si l'on veux afficher plusieur collones ?

Dans ce cas, Il faut choisir le composant le plus adapté, le DataViewGrid. Mais du coup ta structure de donnée devra peut être évolué...

je ne trouve pas la syntaxe pour les DisplayMember, il ne m'affiche toujours que le dernier

Je ne comprend pas, le dernier quoi ?
