Hi, with Prometheus RadAjax the RadAjaxManager himself do not appear anymore in the propertybilder. We Cannot add control to update in case of RadAjaxManager.AjaxRequest are called from client side. We need to put manually the entry in the aspx side page.
I retest with the old AjaxManager and the AjaxManager are present in the Property Builder.
