You would also need to access the TKCalendarMonthPresenter
in the renderer and through its Style
set WeekNumberCellWidth property to the needed width value. Please check the snippet below for the exact approach:
public class CustomCalendarRenderer : CalendarRenderer
protected override void OnElementChanged(ElementChangedEventArgs<
if (Control.Presenter is TKCalendarMonthPresenter)
(Control.Presenter as TKCalendarMonthPresenter).Style.WeekNumberCellWidth = 50;
I hope I was of help.
