[Solved] how set the calendar hours

[hayula]

Hi,

I set the “SelectableDateStart” property to be now,

After I open the calendar the hours are not on the hour

Im expect that the start hour in the calendar will be the next hour that is valid
is it possiable?
thanks,

Hi hayula,

Thank you for contacting us.

You can use the following helper class with DateTime extension methods:

public static class DateTimeExtensions
    {
        public static DateTime Round(this DateTime date, TimeSpan span)
        {
            long ticks = (date.Ticks / span.Ticks) + (span.Ticks / 2) + 1;
            return new DateTime(ticks * span.Ticks);
        }
        public static DateTime Floor(this DateTime date, TimeSpan span)
        {
            long ticks = (date.Ticks / span.Ticks);
            return new DateTime(ticks * span.Ticks);
        }
        public static DateTime Ceil(this DateTime date, TimeSpan span)
        {
            long ticks = (date.Ticks + span.Ticks - 1) / span.Ticks;
            return new DateTime(ticks * span.Ticks);
        }
    }

... and to get the first time value bigger than the DateTime.Now.TimeOfDay should be set to the SelectedTime property of your TimePicker like:

this.timePicker.SelectedTime = DateTime.Now.Ceil(TimeSpan.FromHours(1)).TimeOfDay;

Hope this will help. Should you need more support get in touch with us.
