Web API Service

To access a Web API service from the client, use the createStore method which is part of the DevExtreme.AspNet.Data extension. This extension also allows you to process data for DevExtreme components on the server. The server-side implementation is available under the ListDataController.cs tab in the ASP.NET MVC version of this demo.
