Block label editing in day/week view

Hi again!

I would like to know how to block my user from changing the label of the event. In my case, I want to block the editing of the label from past events.

Hello,

You need to set read-only mode for description section in the Lightbox or for entire event:
docs.dhtmlx.com/scheduler/readon … oxssection

Yes, I had configured the entire event as readonly but did not work. I tried to set only the description section but it did not work either.

Can you show any kind of a sample, where issue occurs ?

Above links contains working samples, so core functionality definitely works, problem can occurs if you try to use the readonly lightbox for one events and editable lightbox for other events, as scheduler do not repaint the lightbox each time and renders it once and reuses later.
