Quite often within mobile applications, there will be a reason to deal with dates. When working with dates, you will probably need some sort of user input to select a date. This could occur when working with a scheduling or calendar app. In this case, it is best to provide users with a specialized control that allows them to interactively pick a date, rather than requiring users to manually type a date. This is where the DatePicker control is really useful.
XAML
<DatePicker Date="09/12/2014" Format="d" />
Code
var datePicker = new DatePicker{
Date = DateTime.Now,
Format = "d"
};
