Bonsoir.
ça fait 2 jours que je bloque sur la création d'une grille avec DevExpress :/.
Ma grille s'affiche, mais il m'est impossible d'effectuer des actions de base.

bon alors ... il se passe quoi ?
ma grille s'affiche avec des informations, jusque là c'est niquel. Mais après les choses se corcent !
lorsque je saisie des données dans les champs texte pour une recherche dans ma grille, voilà le contenu que j'obtiens dans mon objet "GridViewColumnState column" dans "IndividualCustomerList_Filtering" :

Code :

6
 
FieldName = ""
FIlterExpression = null
GroupIndex = -1
SortIndex = -1
SortOrder = None

Du coup, rien le marche :/

Lorsque j'utilise la pagination avec a liste déroulante pour choisir le nombre réponses par page, la valeur que j'obtiens dans mon objet "GridViewPagerState pager" reste toujours 10 (valeur par défaut semble t'il).

Je ne vois pas où est mon erreur. Je commence à craindre une incompatibilité entre la dernière version de DevExpress et les versions récentes de jQuery !!
Svp, dites-moi que ce n'est pas ça, car ce ne serait pas bon pour moi ^^.
