Property value

Type: System.String [.NET] | Platform::String [C++]

The display format for the month value.


Change the format of the month picker by setting the MonthFormat property.

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

format patternformat template
{month.integer} | {month.integer(n)} month.numeric
{month.full} | {month.abbreviated} | {month.abbreviated(n)}month | month.full | month.abbreviated


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 month picker always shows 2 digits, including a leading 0 when needed. You can also combine multiple format patterns. For example, you can combine the {month.integer} and {month.abbreviated} formats to make the month picker show the month number and name, like this: 12 Dec. 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.


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 month number and name in the month picker. There is no equivalent format template for this format.

<DatePicker MonthFormat="{}{month.integer} {month.abbreviated}"/>
