The information you provide is not sufficient for us to understand your problems and your scenario. Would it be possible for you to send us a simple running
page reproducing the problems you have using RadDock Prometheus and the Rating control provided by the AJAX Control Toolkit - please, include all stylesheets, folders, etc. As I am not sure what you refer to with " about the AJAX using XML and RADAJAX does not..." and how it affects your project, I kindly ask you to send us the link of the forum thread where you red so and also provide us with more information about your specific project, what you expect to happen and what does not. To be able to attach files, you need to open a support ticket as demonstrated in the attached instructions.
