I have a problem. It has to do with the AutoComplete control. Well first things first, i write in VB.net and suspect the problem may arrise from compatability with that.

The thing is i can run sample applications with the toolkit, works fine. But when i want to put it to use, namely change code from C# to VB the film snaps, so to speak.

Well some of the controls work, some don't or cause direct script errors. The control i am interested in (was actually going to build it when i saw the new release) is the AutoComplete control.

I have been doing some with custom, user and rendered controls with .net in the past and am positively thrilled about the outlook, but it's gotta work. So here follow the details, i really hope i am doing something wrong, that it can work:

Step one was to convert the web service associate with the example which was done by creating a new AJAX enabled website, then adding reference to the AjaxControlToolkit

The service in VB.net looks like this (and works if navigating to it by the .asmx extention):

'---- END of File listing AutoComplete.asmx.vb :

So far so good. I was using a single page web application to test this, so i cleverly named the form just like in the sample, but omitted to use the master/ detail page structure.

The page looks like this (and produces no result, no nice drop down div to be navigated into with arrow keys or anything, nothing happens when i run this:)

'-------------File listing Default.aspx------------------

<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register

'-------------End of File listing Default.aspx------------------

As you may notice it is a complete copy of the AjaxControlToolkit example, with the only difference that i have allowed myself to register the toolkit using the AJAX prefix instead of the longer ajaxToolkit tagprefix.

Can you assist in this? I will be bouncing about in the lab cheering with spontaneus 'the wave's and crowd sounds in your general direction if you can

Secondly, have you had a working version of the AutoComplete control running? ( that i might know the source of the error is touching my keys )

Heureka!

Well it did seem too easy to blame the creators ;-)

I was fortunate enough to find the error myself, hence will hereby share it. My fault was in total not to  add the associative scripting, like you can see below in red.

Inherits System.Web.Services.WebService

<WebMethod()> _

Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()

Little in between me and google-suggest like interfaces! thx Microsoft

Brilliant move with the AjaxControlToolkit, once we got those demo controls nailed down for details, system.web.extentions is ever so much more easy to approach, hardly have to SOAP anything manually or even touch the JavaScripts /\/\/\/  (<= MSwave)

Cheers all,

Ok, well, I figured it out. As a help to others, here comes the answer

<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
<Script.Services.ScriptService()> _
Public Class AutoComplete

Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()

It should be a ScriptService tag, but it should be placed in the right section. Some examples show it like this,
and it wont work:

Inherits System.Web.Services.WebService
<WebMethod()> _
<Script.Services.ScriptMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()

Your code looks right!  Just some extra info:

• ScriptService is required on the class.
• WebMethod is required on the methods.
• ScriptMethod is optional on the methods.  With no options, it does nothing, so you may as well leave it off.  However, it's useful if you want to use XML serialization (instead of JSON) or an HTTP GET instead of POST.  See http://ajax.asp.net/docs/mref/T_System_Web_Script_Services_ScriptMethodAttribute.aspx.

Thank you Very much it was very helpfull
