Lorsque je suis en affichage normal pas de soucis, le CODE s'affiche bien, par contre dès que je suis en mode édition (EditItemTemplate) ou en mode insertion (InsertItemTemplate) le code initial dans la TextBox est Ok mais lorsque je clique sur le bouton Update ou Insert une valeur Vide est transmise à la base de données, la valeur saisie dans la TextBox n'est pas transmise à la base : en conclusion l'Eval("CODE") - one way binding -fonctionne mais pas le Bind("CODE") -two way binding.
Quelqu'un peut-il m'aider ?
