I have several data-driven custom built webparts that work fine in the visual studio. Followed a blog http://gj80blogtech.blogspot.com/2010/04/configure-ajax-in-sharepoint-2007.html to the letter to incorporate AJAX as some of my webparts use update panels and tab panels.
My custom web parts are listed in the web parts library and when I click on the ones that use Ajax I get the following errors: "A ScriptManager is required on the page to use ASP.NET AJAX Script Components. " and "The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it. " This is for 2 separate web parts.
In the master page I added the toolkit tag as was suggested, in fact I tried 3 different versions:
< ajaxToolkit:ToolkitScriptManager ID="ScriptManager1" runat="server" />, < asp:ToolkitScriptManager ID="ScriptManager1" runat="server" />, < cc1:ToolkitScriptManager ID="ScriptManager1" runat="server" /> because in the article there are instances of all versions.
First I've eddited the default.master by going directly to the file rather than using SharePoint Designer. I've also included the <%@ Register TagPrefix="ajaxToolkit" assembly="AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28F01B0E84B6D53E" Namespace="AjaxControlToolkit" /> in the master page, even though it is also in the web.config file.
Does anyone has any idea as to what I might be doing wrong? Thanks, EJM
