This demo illustrates the following:
-
Locale-dependent format The DateBox formats values based upon a user's locale. This is the default format. As such, you do not need to define the displayFormat property. Refer to the following help topic for more information: Localize Dates, Numbers, and Currencies
-
Built-in predefined formats DevExtreme supports various predefined formats. You can use simple strings or shortcuts that define commonly used date formats instead of complex expressions. Review the linked document for a list of values you can assign to displayFormat. This demo uses the "shortdate" format.
-
LDML pattern Use an LDML pattern to construct a custom date-time format string. This demo sets displayFormat property to "EEEE, d of MMM, yyyy HH:mm". This expression displays week day, day number, month, year, hour, and minute. The editor displays the formatted value. Refer to the following help topic for information about supported format characters: Custom Format String.
-
Format with literal characters Specify the displayFormat property as a string that contains literal and LDML characters. Wrap any characters that are not part of the LDML pattern in quotation marks - otherwise, they may be interpreted as wildcards. In this example, if you remove quotation marks from the word "Year", the letter "a" is interpreted as an "AM/PM" placeholder.
You can also use an input mask in the DateBox. Input masks ensure that input values match the displayFormat (set the useMaskBehavior value to true).
For additional formatting-related information, please refer to the following help topic: Value Formatting.
