Using Intl
Documentation
DevExtreme supports localization via Intl API. To apply localization, link or import dictionaries and set the locale with the DevExpress.localization.locale() method. Refer to the Localization article for more information on localization properties.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
