WPF Date & time controls
The DateTimePicker provides for entry and editing of dates and times in a text-box-like format. It supports system date and time formats and custom formats.
The MonthCalendar allows users to select a date from a calendar display. It supports both keyboard and mouse selection.
The DropDownDatePicker combines a DateTimePicker and a MonthCalendar to enable compact display and rapid editing of dates with the ease of use of a point-and-click display.
All date and time controls support localization and will be formatted according to the system culture. This can of course be changed, allowing you to produce applications for a global audience.
