CalendarView for Xamarin.Android: Special Slots

With R3 2019 release of Telerik UI for Xamarin RadCalendarView for Xamarin.Android provides the option to define a collection of special and restricted time slots in order to make them noticeable across the timeline of the Day and MultiDay views.

You just need to prepare a collection of Com.Telerik.Widget.Calendar.Slots.SpecialSlot objects, create a Com.Telerik.Widget.Calendar.Slots.SlotAdapter object and assign the SpecialSlots collection to its Slots property.

Every SpecialSlot has the following properties:

  • StartDate;
  • EndDate;
  • IsReadOnly: When set to True the slot is disabled (restricted), meaning the end user wouldn't be able to create or modify appointments at that slot;
  • SlotColor: the background color applied to the defined slot;

Below you can find a quick example how to create special slots.

RadCalendarView calendarView = new RadCalendarView(Activity);
calendarView.DisplayMode = CalendarDisplayMode.Day;

Calendar calendar = Calendar.Instance;
calendar.TimeInMillis = calendarView.DisplayDate;

calendar.Add(CalendarField.Hour, 12);
long startTime = calendar.TimeInMillis;
calendar.Add(CalendarField.Hour, 2);
long endTime = calendar.TimeInMillis;

SpecialSlot lunchSlot = new SpecialSlot(startTime, endTime) { SlotColor = Color.LightPink  };
var slotAdapter = new SlotAdapter(calendarView);
slotAdapter.Slots = new List<SpecialSlot>() { lunchSlot };
calendarView.SlotAdapter = slotAdapter;

Here is the result:
