When i put TPlanner in plDay mode, I don't know how to stablish the proper date, according to a TPlannerMonthView date selection. in order to sincronize both controls.
Given that in this mode, there is no fixed relationship between a date and the position in the Planner, there is no date associated by default with the PlannerItem StartTime / EndTime. This is because the Planner can be in multiday, multiresource, combined multiday / multiresource modes. So, the application should be designed to know the mapping between position & date and do the conversion of position (PlannerItem.ItemPos) and date in application code.
thank you Bruno.
