DatePicker control – PB Docs 150

DatePicker control

A DatePicker control makes it easy for users to select
a date. It has two parts: a drop-down list box that displays the
date in a selected format, and a grid that resembles the MonthCalendar
control. Unlike the MonthCalendar control, which can be used to
select a range of dates, the DatePicker control is used to select
a single date.
