DatePicker.DayFormat Property

public:
 property Platform::String ^ DayFormat { Platform::String ^ get(); void set(Platform::String ^ value); };

winrt::hstring DayFormat();

void DayFormat(winrt::hstring value);

public string DayFormat { get; set; }

var string = datePicker.dayFormat;
datePicker.dayFormat = string;

Public Property DayFormat As String

<DatePicker DayFormat="formatString"/>

Property Value

The display format for the day value.

Examples

Here's a DatePicker formatted using format templates, and a DatePicker formatted using format strings. Both DatePicker controls look the same when the app is run because the formatting is equivalent.

<!-- DatePicker formatted using format templates. -->
<DatePicker DayFormat="day" MonthFormat="month.numeric" YearFormat="year.abbreviated"/>

<!-- DatePicker formatted using format patterns. -->
<DatePicker DayFormat="{}{day.integer}" MonthFormat="{}{month.integer}" YearFormat="{}{year.abbreviated}"/>

Here's a DatePicker that combines 2 format patterns to display both the numeric date and the day of the week in the day picker. There is no equivalent format template for this format.

<DatePicker DayFormat="{}{day.integer} {dayofweek.abbreviated}"/>

Remarks

Change the format of the day picker by setting the DayFormat property.

The string content of each ComboBox in the DatePicker is created by a DateTimeFormatter. You inform the DateTimeFormatter how to format the day value by providing a string that is either a format template or a format pattern. Common templates and patterns for day values are listed in the following table.

In some cases, using a format pattern gives you more precise control over the formatting. For example, you can use a format pattern to specify that the day picker always shows 2 digits, including a leading 0 when needed. You can also combine multiple format patterns. For example, you can combine the {day} and {dayofweek.abbreviated} formats to make the day picker show both the numeric date and the day of the week, like this: 14 Thu. See the Examples section for more info.

For the complete list of format templates and format patterns, see the Remarks section of the DateTimeFormatter class documentation.
