Spell Check As You Type

[Phil]

Hi

Can you confirm if the radEditor supports spell checking as you type i.e. like Microsoft Word where red lines appear beneath incorrectly spelled words as you type them.

thanks

Hello Stephen,

All major browsers (except Internet Explorer) offer their own built-in spellcheckers that perform inline spell checking out-of-the box in the editable elements: textareas, editable iframe and div elements. The content area of RadEditor is editable IFRAME( or DIV if ContentAreaMode is set to DIV) and the required spell as you type feature is offered out-of-the box by Firefox, Chrome, Safari and Opera. It is very likely that the inline spellchecking will be also implemented by IE developers in some future versions of Internet Explorer.

At present, we do not plan to provide spell as you type feature 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. The spell as you type feature will make often callbacks to the server which will also decrease the server performance if a large text is edited or multiple users are using the editor in the same time.

There is a public PITS item for you feature request. If many users request it we will definitely consider its implementation. Here you can find the PITS Issue: Public URL.

Currently, your clients could use the inline AJAX spellchecker of RadEditor which you can test in this live demo: AJAX Spell Checker or the built-in spell as you type spellcheckers of Firefox, Chrome, Safari and Opera.
