I'm trying to use the Ajax AutoCompleteExtender, but it's not working. Where am I going wrong. Other Ajax controls like update panel, are working fine. Using EntityFramework, C#,Chrome.

ASPX:

<asp:TextBox ID = "txtSearch" runat="server">
 <ajax:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" 
TargetControlID="txtSearch" MinimumPrefixLength="2" EnableCaching="true" 
CompletionSetCount="10" CompletionInterval="1000" ServiceMethod="GetCountries">
</ajax:AutoCompleteExtender>

ASPX.CS

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]

public static IEnumerable<string> GetCountries()
 {
   return objDAL.GetCountries(txtSearch.Text.Trim());
 }

DAL:

public IEnumerable<string> GetCountries(string text)
 {
   return MyDB.tblCountries.Where(e=>e.CountryName.StartsWith(text)).
          Select(e=>e.CountryName);
 }

Also tried

public static List<string> GetCountries()
 {
   return objDAL.GetCountries(txtSearch.Text.Trim()).ToList();
 }
