Make DateTimePicker work as TimePicker only in WinForms

A snippet out of the MSDN:

'The following code sample shows how to create a DateTimePicker that enables users to choose a time only.'

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Time;
timePicker.ShowUpDown = true;

...or alternatively if you only want to show a portion of the time value use "Custom":

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Custom;
timePicker.CustomFormat = "HH:mm"; // Only use hours and minutes
timePicker.ShowUpDown = true;

You want to set its 'Format' property to be time and add a spin button control to it:

yourDateTimeControl.Format = DateTimePickerFormat.Time;
yourDateTimeControl.ShowUpDown = true;

If you want to do it from properties, you can do this by setting the Format property of DateTimePicker to DateTimePickerFormat.Time and ShowUpDown property to true. Also, customFormat can be set in properties.

The best way to do this is this:

datetimepicker.Format = DatetimePickerFormat.Custom;
datetimepicker.CustomFormat = "HH:mm tt";
datetimepicker.ShowUpDowm = true;
