La Modification en ligne d'un GridView

J'ai un affichage de la grille que j'ai renseigné dans le code derrière. J'ai activé l'AutoGenerateEditButton sur ce GridView, mais maintenant ne peut pas travailler sur la façon d'activer la modification en ligne.

J'ai regardé pour les échantillons, et n'ai pas trouvé quelque chose d'utile. Ci-dessous est une copie de ma page ASPX et puis le code derrière.

    La façon la plus simple pour activer l'édition est de donner le contrôle gridview un sqldatasource dont la mise à jour des paramètres et un updatecommand.
    ici, c'est plus sur que:

    Si vous n'êtes pas obligé d'utiliser un GridView, je les recommande vivement à l'aide d'une ListView:

    http://www.codedigest.com/Articles/ASPNET/105_EditUpdateDelete_and_Insert_in_ListView_Control.aspx

    Pour moi, la liste est plus souple et facile à mettre en œuvre.
