Overview
Documentation
The DateBox is a UI component that displays the date and time in one of DevExtreme predefined formats or a format defined in an external localization library, or a type in the required date/time value. In this demo, the «Custom format» DateBox’es value is formatted using the Globalize library. Alternatively, you can use Intl.
Feel free to share demo-related thoughts here.
