First it's possible to retrieve the data from the editor using the client side script.

Here is a demo:

Code is as followings:

function getHTML()
{
    // get the cute editor instance
    var editor1 = document.getElementById('<%=Editor1.ClientID%>');
    
    // Get the editor HTML
    document.getElementById("myTextArea").value = editor1.getHTML();
}  


Here is another demo which show you use the CuteEditor in ASP, PHP and JSP applications.
