DataGrid ne s'affiche pas

**akaii** · 12/11/2008, 08h59

Salut,

Pourquoi mon DataGrid ne s'affiche et je cale... donc j'aurais bien besoin d'un coup de main.

J'ai deux formes Default.aspx et UserListTest2.aspx.

Dans la premiere j'ai 3 champs a remplir par l'utilisateur et un bouton ("Bouton Test 2") qui appelle la deuxieme forme ou doit s'afficher un DataGrid ("dataGridUserList").

Aucun message d'erreur et la requete SQL doit passer car je suis dans la BD.

Voici les deux formes
