salve prima di tutto.

Sto effettuando delle prove per prendere un pò la mano con ajax e stavo appunto vedendo l'autocompleteextender. Sembra molto facile da utilizzare si indica su quale textbox deve lavorare. Si aggiunge al sito un Webservice che contenente una funzione che ritorna un array di stringhe...epuure non va

ecco il codice: (utilizzo microsoft visual studio 2005)

default.aspx


<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
