Question

I am trying to develop a custom control for Umbraco that would allow us to dynamically set the length of text allowed in TinyMCE. I have already implemented something similar for a normal text box but I am stuck on how to implement it with the RTE. I found no .dll that I could reference and although there is a little bit of code on their site; it is only concerned with the javascript.

Any ideas on where to start would be great.

You can implement a tinymce init parameter “max_chars” yourself

tinyMCE.init({
   ...
   max_chars : "10", // place your char limit here
   setup : function(ed) {
      ed.onKeyDown.add(function(ed, evt) {

        if ( $(ed.getBody()).text().length > ed.getParam('max_char')){
          e.preventDefault();
          e.stopPropagation();
          return false;
        } 

      });
   },
   ...
});
