The Window's skin file determines the look of the dialog windows, but not their inner content. The content of the dialogs is styles by the Widgets.Default.css file.
In addition, when you want to use a custom skin for a Prometheus control, you should set
to the RadEditor server tag and register the needed CSS file manually with <link> or <style> element in the <head> of the web page.
As for the AJAX spellchecker, you can style its look by using these CSS classes:.rade_ajaxspell_wrapper
- this is the class applied to the table wrapping the spellchecker's yellow bar..RadEXhtmlButton
- this is the class applied to the two buttons - "Finish" and "Cancel"
Hope this helps.
