Ajax AutoComplete Problem

I have been trying to get the AutoComplete work without success. (many Days)

I have a deveplement Server 2003, XP workstation with VS2005 and IE7, and have check this with a workstation with Win98&IE6

I am using the demo from the Ajax.net video's

I have install the lastest ajax onto the server and the bin directory has: AjaxControlToolkit;AjaxControlToolkit.dll;AjaxControlToolkit.dll.refresh;AJAXExtensionsToolbox.dll;BuildVsi.dll;JavaScriptCommentStripper.dll;System.Web.Extensions.Design.dll;System.Web.Extensions.dll;Tools.dll;Tools.netmodule.

I can get things like the CollapsiblePanelExtender working, The demo on the ajax web site works.

The page displays as expected, but when I type the 3rd character, nothing happens

Filddler gives me an error 500, on the 3rd 'a'

I also had to create a folder named 'GetCompletionList' with a copy of autocomplete.asmx in it to fix an error 404 that fiddler gave me, which may be anther issuse.

I can call the web service and get results from it and '/js' gets me the option to download the JavaScript.

I have resolved this

in:-

<cc1:AutoCompleteExtenderid="AutoCompleteExtender1"runat="server"ServiceMethod="AutoComplete.asmx"

ServicePath="GetCompletionList"TargetControlID="TextBox1">

</cc1:AutoCompleteExtender>

I had theServiceMethod& ServicePath attributes back to front

Note: Using Fiddler helped, couldn't see this problem initially due to its simplicity

"I also had to create a folder named 'GetCompletionList' with a copy of autocomplete.asmx in it to fix an error 404 that fiddler gave me, which may be anther issuse."
