Hi all

I have two drop down lists on my page, when the user selects an item in the first list the second list should load related data from a database table.

I am trying to use AJAX to prevent post-backs, but I am running into a number of problems:
1. Syntax error - it seems that this error is related to the command:
Code: 
Ajax.Utility.RegisterTypeForAjax(GetType(AjaxData))
When I remove this line I get no errors.

2. Microsoft JScript runtime error: 'AjaxData' is undefined occurs in the javascript file
Code: 
function LoadType(identifier)
{
  var type = identifier.options  [identifier.selectedIndex].value;
  AjaxData.GetSubType(type, LoadType_CallBack);
}
I cannot under stand why the code will not work as I have the exact same code in a sample project and it works perfectly.

I have the Ajax.dll in the bin folder and I haved added the line:
Code: 
<httpHandlers>
      <!-- Register the ajax handler -->
      <add verb="POST,GET" path="ajaxwrapper/*.ashx" type="Ajax.PageHandlerFactory, Ajax" />
    </httpHandlers>
to the web.config file
