Is there a way to disable the "selectable" property of a cell? I would like to prevent the TimeRange Selection on certain slots, but in the BeforeCellRender event doesn't seems to be possible. Maybe a client workaround? Thank you,
At this moment it's only possible to disable the cells for the whole row by marking it as parent using PreventParentUsage. See also:

Disabling individual cells will be added in one of the future releases.
