I am having issues with the AjaxControlToolkit. I started with the 3.5 version and backed up hoping for some love but I am still stuck in quiet desperation trying to meet my impossible deadline. :) I have changed my masterpage to use the ControlToolkitScriptmanager.
System.Web.Extensions references v18.104.22.168 throughout the config. Version of the toolkit referenced in the VS2010 webpart project verified as 3.0.30930.28736
The issue is that no matter what control or extender I try to use I receive the following error:
The base class includes the field '(control/extender name)', but its type (AjaxControlToolkit.(control/extender)) is not compatible with the type of control (AjaxControlToolkit.(control/extender)).
If it would help I would post the entire web.config. If anyone has a working setup with a version of the toolkit I would love to get a copy! I will have to get Silverlight going next.
