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.

The problem in your case comes from the fact that you are using the RadImageEditor with ToolsLoadPanelType="XmlHttpPanel". This means that the ImageEditor will use RadXmlHttpPanel to load its dialogs and the XmlHttpPanel has known issues when used with RadScriptManager and RadStyleSheetManager described in its Known Issues help section.
My suggestion is to set ToolsLoadPanelType="AjaxPanel" to the ImageEditor. Alternatively, you can disable the script and stylesheet combining on the respective managers.

Kind regards,
