JavaScript/jQuery DataGrid API

The DataGrid is a widget that represents data from a local or remote source in the form of a grid. This widget offers such basic features as sorting, grouping, filtering, as well as more advanced capabilities, like state storing, export to Excel, master-detail interface, and many others.

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 DataGrid 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.
