Web API Service
Documentation
This example demonstrates the DataGrid widget communicating with a Web API service. All data editing and data processing operations are delegated to the server. The DevExtreme.AspNet.Data extension’s DevExpress.data.AspNet.createStore method configures access to the server from the client. The server implementation is available under the DataGridWebApiController tab in the ASP.NET MVC version of this demo.
Thank you!
