Message: 'AjaxControlToolkit' is undefined

Hi,

I have successfully implemented SmartPart for sharepoint 2007 with a asp.net control.

I am currently trying to implement this asp.net control with Sharepoint 2010 using this smartpart.

I have successfully added the new smartpart to sharepoint and added the asp.net control. I am now receiving the following error:

Message: 'AjaxControlToolkit' is undefined. This happens the first time that there is a call to the ajax control toolkit.

After that it works fine. Has anyone else seen similar issues or have any ideas?

Thanks,

Coordinator

You could be having a version mismatch on the AjackControlToolkit as the original in 2007 version is older than the one supplied by default with 2010 SharePoint.
