Hi,
with latest v16.1.0.24 SfSchedule, set the Locale="de" in XAML gives following exception (tested only with UWP, worked with prev version):
System.FormatException: Input string was not in a correct format.
at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
at Syncfusion.SfSchedule.UWP.DayViewManager.TimeToPosition(SfSchedule schedule, DateTime dateTime, DayViewInfo dayView, AppointmentControl appointmentControl)
at Syncfusion.SfSchedule.UWP.DayViewPanel.CalculateAppoin
without Locale="de"it works. I removed all other settings from XAML to isolate the problem.
On german windows 10, if it matters..
Regards.
