Bonjour a tous,

Je souhaiterai créer une combobox dans un datagridview. J'ai essayé de plusieurs manière d'implémenter cela (créer une var list<>,créer une arraylist, ect...) mais aucune ne fonctionne. Le truc c'est que ma colonne combobox existe, j'ai réussi a la créer donc y a pas de soucis la-dessus. Mais la combobox est grisée et vide. Je ne peux pas cliquer dessus, ni la dérouler. J'ai essayer de modifier ses propriétés (Enabled = true, Debug qui montre que ma liste contient bien les éléments, ect..).

Merci !

Mon code :

Code : Sélectionner tout - Visualiser dans une fenêtre à part
