  Hi i am interested in getting an underline or some other way of showing misspelled words.
  I have had a look at the examples, all of them require a popup that checks the spelling.
  Is there a way to have the spelling checked on the whole text and all possible mistakes underlined?
  
  Thanks

  Hello Andrew,
  
  Yes, it is possible - but only if you use RadEditor and its inline spellchecker.
  Please review the following demo (and press the Spellcheck button to initiate the process):

  Thank you for your help.
  Not exactly what i am trying to do.
  I don't really want the popup box. I just want the user to be notified after he has typed the word that it is in fact spelled incorrectly.
  Sort of the way word does.

  Hi Andrew,
  
  The fully automatic inline spellchecking is currently not supported by RadEditor.
  
  The content area of the editor is an editable IFRAME and allows to highlight the misspelled words by wrapping them inside a <span> tag with inline css and class attributes, e.g.
  
  <span class="RadEWrongWord" id="RadESpellError_0" style="background-color: #ffff00;">misspelledword</span>
  
  There is no other way to highlight the misspelled words except using HTML tags and css.
  
  If we enable the automatic spellchecking this will drastically decrease the editing performance and slowdown the browser, because we should insert a span tag with inline style for every newly inserted misspelled word.
  
  Please, note that Firefox offers built-in inline spellchecking and your users could use it instead of the editor's spellchecker.
  
  Kind regards,

  I presume this is still not possible?  We are looking to implement a solution that allows user to see misspelled words as they type (much like Word).
  
  Thanks,

  Hi Jared,
  
  For the time being, we do not plan to provide automatic spellchecking while typing in RadEditor due to performance issues. If you edit large text then this will decrease the typing / editing performance, because the JavaScript code has 10 times slower performance compared to native compiled code. RadEditor also runs multiple content filters on the client that will additionally decrease the performance when spell checking large content.
  
  All major browsers (except Internet Explorer) offer their own built-in spellcheckers that perform inline spell checking in the editable elements: textareas, editable iframe and div elements. The content area of RadEditor is editable IFRAME. I hope that this feature will be implemented by IE developers in one of the next version of this browser and RadEditor will support it.
  
  Best regards,
