AddHandler ne fonctionne pas

Question

Pourquoi mon addhandler ne fonctionne-t-il pas?

Dans le sous-type "CreateTagStyle", le AddHandler ne se déclenche pas lorsque le LinkButton est cliqué. Y at-il une raison pour laquelle les addhandlers ne peuvent pas être ajoutés à certains points du cycle de vie de la page?

Answer 1

Est-ce que cela fonctionne au moins une fois? ItemDataBound ne s'exécute pas en publication, de sorte que vos événements ne seront pas recâblés en cas de publication. Vous devez utiliser ItemCreated à la place:

• Event sequence

• Distinguishing the major differences between ItemCreated and ItemDataBound events
