I am using a RadUpload control to select an image on the client machine to load into the image editor. I use a RadAjaxManager and its OnAjaxRequest event to load the image into the editor. That all works fine except I can't get the RadImageEditor's dialogue's to render correctly. The dialogue's work for the most part except their controls don't display images and the slider in the zoom dialogue renders as a set of link buttons. I see in the known issues that if the image editor is in an update panel the UpdateMode should be set to Conditional. But I don't know how to handle this with the RadAjaxManager.
