I have the following ASPX:

         <asp:TextBox ID="tbTextBox" runat="server"></asp:TextBox>
        <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" 
                                  TargetControlID="tbTextBox"
                                  ServiceMethod="GetStudentNames"
                                  ServicePath="Student_WS.asmx"
                                  MinimumPrefixLength="1"/>

and my vb code is:

 
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.Data

<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Public Class Student_WS
     Inherits System.Web.Services.WebService

    <WebMethod()> _
    Public Function GetStudentNames(ByVal prefixText As String, ByVal count As Integer) As String()
        Dim Students() As String
        Dim aList As New ArrayList
        Dim taStudents As New StudentTableAdapters.tblStudentTableAdapter
        Dim dtStudents As DataTable = taStudents.Get_Student
        For Each row As DataRow In dtStudents.Rows
            aList.Add(row("nvcStudentFirstName").ToString)
        Next
        Students = DirectCast(aList.ToArray(GetType(String)), String())
        Return Students
    End Function
End Class

This doesn't work. What am I doing wrong?
 

While we work closely with the ASP.NET AJAX team when developing the Toolkit, they're the real experts on general ASP.NET AJAX issues. Your problem doesn't seem to be directly related to the Toolkit, so we'd appreciate if you considered posting to one of the other newsgroups such as AJAX Discussion and Suggestions. Your post will be more helpful to others looking for similar advice if it's in the right place. Thank you!

I will. Thx.
