I'm trying to create a Autocomplete search in Ajax using ajax toolkit 4.

I get no errors with the following code but the control does not work at all.

Ascx and asmx are placed in the usercontrol folder and the dll in the bin folder.

As I see it there could be two possible problems:

• Ajax toolkit 4 does not work with umbraco 4.5
• The webservice method is not found

ascx.cs file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace ParvusProductSearch
{
    public partial class ProductSearch : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
       
        protected void Button1_Click(object sender, EventArgs e)
        {
            string text = TextBox1.Text;

            Response.Redirect("search.aspx?searchterm=" + text);
        }

    }
}

ascx markup
