Entre autres, j'ai deux pages dans mon projet de site Web. Default.aspx et TeacherControlPanel.aspx. L'utilisateur donne ses informations d'identification dans Default.aspx, un cookie est créé, puis il est Server.Transfer() ed à TeacherControlPanel.aspx. TeacherControlPanel.aspx possède un bouton de déconnexion et un autre bouton nommé 'Envoyer un courrier'.asp.net spooky chargement de la page
Si l'utilisateur appuie sur le bouton de déconnexion, le cookie est supprimé et il est redirigé vers Default.aspx.
Si l'utilisateur ferme le navigateur sans se déconnecter, lorsqu'il ouvre la page Default.aspx, il est automatiquement redirigé vers TeacherControlPanel.aspx car le cookie est présent.
Maintenant, tout fonctionne correctement, sauf que j'appuie sur un bouton 'Send Mail' sur TeacherControlPanel.aspx puis que Default.aspx est chargé et que TeacherControlPanel.aspx est chargé mais que le gestionnaire d'événements Button n'est pas en cours d'exécution.
Pourquoi Default.aspx se charge à nouveau et qu'arrive-t-il à l'événement Button?

Pourriez-vous poster le code? Il sera beaucoup plus facile de déboguer de cette façon. –
plz voir la mise à jour. –
