J'ai eu gridview qui obtient des données de la base de données en fonction de deux événements. Le premier de la méthode, le second lorsque sélectionné ddl.it a bien fonctionné, j'ai fait la pagination et quand je passe par les pages de pagination Je dois cliquer deux fois sur le numéro de page pour aller à cette page et toutes les pages obtiennent les mêmes données pour la première page.pagination dans gridview obtenir les mêmes données pour toutes les pages

gridview obtenir aucune donnée – Myworld
S'il vous plaît voir mon modifier en réponse à votre commentaire. –
Cela a bien fonctionné. Quand j'ai rafraîchi la page en sélectionnant ddl, je vais à la page précédente où j'ai choisi. – Myworld
