If Planner.Mode.PlannerType = plDay, the default assumption is that the Planner works in multi-day mode for a non DB-aware Planner which I assume you are using. If you do not use multiday but treat positions as resources, only the time part of CellToTime() makes sense and the date for the Planner is the same for each position and retrieved via Planner.Mode.Date: TDateTime.
How do I select the Planner (plDay) to use multi day or resources?
I'm struggling to make the columns (7) to have a separate date each in a week.
When you use a non DB Planner, the default assumption is multiday.
Ok, but as a suggestion it could be a new multires property and not increase the dates on each item if the planner.selposition >0 in this mode (multires mode).
We'll consider this.
