The read-only property available on most kendo input fields isn't obvious enough for the end user that a field is disabled. It is a source of confusion as it makes the form look broken rather than read-only. Adding k-state-disabled is important from a form readability perspective, thus it would be very helpful if that class was made available on dropdown lists and masked textboxes so they match the textboxes on forms without having to selectively apply additonal CSS.
