Vista Tutorial - Ajax what could be causing this?

03-18-2008

Hi,

I have setup the AjaxToolKit on my box which works great (cleaned up
their sample code for AutoCompleteExtender). However, when I import
the same code in my current project, it doesn't fire the webservice
that's suppose to return the auto complete results. What could be
causing this in my project? No compilation error, other AJAX
components work fine. Could be something in web.config file? I've
included my code below

<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="Test_Default" %>

<%@ Register assembly="AjaxControlToolkit"
namespace="AjaxControlToolkit" tagprefix="ajaxtoolkit" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Test</title>
</head>
<body>

<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager runat="server"
ID="ScriptManager1" />

<asp:TextBox runat="server" ID="myTextBox" Width="300"
autocomplete="off" />
<ajaxToolkit:AutoCompleteExtender
runat="server"
BehaviorID="AutoCompleteEx"
ID="autoComplete1"
TargetControlID="myTextBox"
ServicePath="AutoComplete.asmx"
ServiceMethod="GetCompletionList"
MinimumPrefixLength="1"
CompletionInterval="100"
EnableCaching="true"
CompletionSetCount="20"

CompletionListCssClass="autocomplete_completionListElement"
CompletionListItemCssClass="autocomplete_listItem"

CompletionListHighlightedItemCssClass="autocomplete_highlightedListItem"
DelimiterCharacters=";, :">
</ajaxToolkit:AutoCompleteExtender>

</form>
</body>
</html>

In my AutoComplete.asmx
<%@ WebService
Language="C#"
CodeBehind="/App_Code/AutoComplete.cs"
Class="AutoComplete" %>

In App_Code folder AutoComplete.cs

using System;
using System.Collections.Generic;
using System.Web.Services;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AutoComplete : WebService
{
public AutoComplete()
{
}

[WebMethod]
public string[] GetCompletionList(string prefixText, int count)
{
if (count == 0)
{
count = 10;
}

if (prefixText.Equals("xyz"))
{
return new string[0];
}

Random random = new Random();
List<string> items = new List<string>(count);
for (int i = 0; i < count; i++)
{
char c1 = (char)random.Next(65, 90);
char c2 = (char)random.Next(97, 122);
char c3 = (char)random.Next(97, 122);

items.Add(prefixText + c1 + c2 + c3);
}

return items.ToArray();
}

}

Thank you
Maz
