Hi Adam,

You can create a custom renderer for the iOS platform and work with the Style property of the TKCalendarDayCell to update its visual appearance.

For example:

Create the custom renderer:

 
 class CustomCalendarRenderer : CalendarRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<RadCalendar> e)
        {
            base.OnElementChanged(e);
            this.Control.Delegate = new CalendarDelegate();
        }
    }

The definition of the Custom Delegate:
class CalendarDelegate : TKCalendarDelegate
   {
       public override TKCalendarCell ViewForCellOfKind(TKCalendar calendar, TKCalendarCellType cellType)
       {
           if (cellType == TKCalendarCellType.Day)
           {
               return new CustomCell();
           }
           return null;
       }
   }

And the CustomCell where you can work with the Style property:

public class CustomCell : TKCalendarDayCell
   {
       public override void UpdateVisuals()
       {
           this.Style.TextColor = UIColor.Purple;
           this.Style.TextAlignment = TKCalendarCellAlignment.Top;
           this.Style.Shape = null;
 
           base.UpdateVisuals();
       }
   }

Hello Adam,

Unfortunately, no easy way to achieve that, however, you can add images as the background of the current/selected cells and imitate the stroke. Please have a look at the attached example which is based on the CalendarCustomization example from the iOS Examples application which can be found in your local Telerik UI for Xamarin Installation. The stroke I have created is far from perfect, however, you should be able to modify the image so that it fits your requirements. You can consider setting it only for the selected cell as well.

Have a great week.
