You can't get the values because the editing content is in an IFRAME . the content of IFRAME would not post to the page that contains the CuteEditor.
so you could just get the Editor1.Text which maybe is "<input name=yourfield value=thevalue> ... "
You could use the Editor1.XHTML to retire the XML string , and parse it into XmlDocument , and get the value as you want .
