Acces textbox.text depuis un webservice

Bonjour a tous,

Je vais surement me faire taper dessus en posant cette question mais je ne trouve pas de réponse.
Je cherche à recuperer la valeur d'une textbox dans un fichier .asmx.vb mais je n'y arrive pas.

J'ai essayer de créer une fonction partager qui me retourne la valeur de la textbox mais je n'ai pas le droit :

Citation:

Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.

Je ne vois pas du tout comment faire, quelqu'un peut-il me guider ?

Merci d'avance.

Oula, quel est le rapport entre un Web Service et une application (tu ne précise même pas si c'est Winforms ou ASP.NET) ?
Qu'est ce que tu cherches à faire exactement ?

Oula effectivement, j'ai oublier que je fait de l'ASP.NET avec VB.NET.

En fait, j'utilise un Webservice pour faire des cascading dropdownlist (via ajaxtoolkit) et je voudrais que ses dropdownlist dépendent de la valeur d'une textbox. Mais je n'arrive pas a acceder à cette textbox.

C'est cette partie qui ne fonctionne pas :
Dim UserID as string
UserID = TBUserID.Text

Merci de votre aide.

Tu devrais passer la valeur de cette textbox en parametre du Web Service.
Le Web Service ne doit pas dépendre d'une quelconque interface (c'est le principe même du service).

Merci de ta réponse mais je suis toujours dans le flou :s
Pourrais tu être un peu plus précis ?

Merci d'avance

Hello,

J'ai finalement utiliser une variable de session pour stocker ma valeur.

Cordialement.

DeWaRs

quand tu initialises la variable de session?
