React Gallery API

The Gallery is a widget that displays a collection of images in a carousel. The widget is supplied with various navigation controls that allow a user to switch between images.

import Gallery from "devextreme-react/gallery"

DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.

The following code shows how to create the Gallery widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
