auto complète asp.net

Question

Pourquoi mon autocomplete script ajax ne fonctionne pas:

Ceci est mon WebService.cs:

using System; 
using System.Data; 
using System.Web; 
using System.Collections; 
using System.Web.Services; 
using System.Web.Services.Protocols; 
using System.ComponentModel; 
using System.Data.SqlClient; 
using System.Collections.Generic; 
    using System.Configuration; 
using System.Web.Script.Services; 



[ScriptService] 
[WebService(Namespace = "http://tempuri.org/")] 

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

public class WebService : System.Web.Services.WebService { 

    public WebService() { 

     //Uncomment the following line if using designed components 
     //InitializeComponent(); 
    } 

    [WebMethod] 
    public string[] GetCountryInfo(string prefixText, int count) 
{ 

string sql = "Select * from questions Where username like @prefixText"; 
SqlDataAdapter da = new SqlDataAdapter(sql,"estudent_piooConnectionString"); 
da.SelectCommand.Parameters.Add("@prefixText", SqlDbType.VarChar, 50).Value = prefixText + "%"; 
DataTable dt = new DataTable(); 
da.Fill(dt); 
string[] items = new string[dt.Rows.Count]; 
int i = 1; 
foreach (DataRow dr in dt.Rows) 
{ 
    items.SetValue(dr["username"].ToString(),i); 
    i++; 
} 
return items; 
} 

} 

mon css:

/*AutoComplete flyout */ 

.autocomplete_completionListElement {
marge: 0px! Important; background-color: hériter; couleur: windowtext; bordure: buttonshadow; largeur de bordure: 1px; style bordure: solide; cursor: 'default'; dépassement de capacité: auto; hauteur: 200px; text-align: à gauche; type de style de liste: aucun; remplissage: 0px; }

/* * Saisie semi-automatique mis en évidence article/

.autocomplete_highlightedListItem { background-color: # FFFF99; couleur: noir; rembourrage: 1px; }

/* article * Saisie semi-automatique/

.autocomplete_listItem { background-color: fenêtre; couleur: windowtext; rembourrage: 1px; }

et zone de texte:

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" CompletionListCssClass="autocomplete_completionListElement" 
    CompletionListItemCssClass="autocomplete_listItem" CompletionSetCount="20" 
CompletionInterval="1000"  DelimiterCharacters=";,:" 
    CompletionListHighlightedItemCssClass="autocomplete_highlightedList MinimumPrefixLength="1" ServiceMethod="GetCountryInfo" ShowOnlyCurrentWordInCompletionListItem="true" TargetControlID="TextBox2" ServicePath="WebService.asmx" runat="server"></cc1:AutoCompleteExtender>
