Ajouter dynamiquement un bouton radio à un gridview
Bonjour, j'ai un grand problème, ça fait une journée que cherche sur le net mais malheureusement sans résultat. Je souhaite ajouter à mon gridview un bouton radio à chaque ligne.
- Mon grid est contenu dans une webpart dans le code utilisé est uniquement c#.
- Je dois gérer le post back quand je sélectionne un radio.
- Je dois sélectionner une seule ligne comme en HTML en spécifiant le nom, mais avec asp.net c'est pas faisable.
