Date Time and Calendar Control in C#

DateTimePicker and Month Calendar

DateTimePicker
DateTimePicker is ideal for choosing a single date and/or time value and requires the same amount of space as an ordinary drop-down list box. When the user clicks the drop-down button, a month calendar appears. The operation of the control from this point is exactly the same as the MonthCalendar control.
