The action response is generated and processed only after saving|updating|deleting, but you are saying that
Do you need to apply readonly after saving data or during loading?
During loading it can be done by above mentioned event, or just providing
<event readonly=“1”
in XML
But another problem … I think I found a bug … readonly is okay in month view but in others not.
Day view - I can change description by double click. I can’t show details of event.
Week view - Same as day view
Year view - I can’t show details of event.
Even if I actived readonly mode for every event in calendar (scheduler.config.readonly_form = true;) still I can change a description in week or day view.
One more time - everything is okay in month view (I can’t change readonly event, but I can show details of this event).
In daily and weekly view is a problem (bugs) = I can’t show details of event but I can change description (via doubleclick).
In a yearly view I just can’t show details.
