    Andy,
     
    There are two ways to set a limit to the characters.
     
    1. Client side check
     
      

    <script language="JavaScript" type="text/javascript" >


    var EditorID = "youreditorID_editBox";

    var editor = document.getElementById(EditorID);

    function     checklength()

    { 

        if (editor.innerText.length>=1000)

        {

            editor.innerText = String (editor.innerText).substring(0,1000);

        }

    }

    editor.onkeypress = checklength;

    </script>

    This way a user cannot type more then 1000 characters

     
    2. Server side check
     
      

     

    <script runat="server">

    public void Submit(object sender, System.EventArgs e)

    {

        string plaintext = Editor1.PlainText;

        if(plaintext.Length > 1000)

            Literal1.Text = "<hr><h2>The maximum length is 1000, Please try again </h2><br>";

        else

        {

            Literal1.Text += Server.HtmlEncode(Editor1.XHTML);

            ' Write the content into your database
            ....

        }

    }

    </script>
