The Getting Started section will walk you through the creation of a sample application that contains RadGridView and RadDataPager bound to a RadDataServiceDataSource.
RadDataServiceDataSource can consume any WCF Data Service. This can be any publicly available Live OData Service or a WCF Data Service that your company has already set-up. In case you don’t have a WCF Data Service running, you can follow this tutorial in order to quickly set-up a self-hosted WCF Service. If you prefer your service to be hosted in a Web Application you can follow this tutorial.
Creating and configuring WCF Data Services is the beyond the scope of the current tutorial. You can find more information regarding WCF Data Services here. The Open Data Protocol Home is another great learning resource. This tutorial will use the publicly available OData feed of the popular Northwind database found at http://services.odata.org/Northwind/Northwind.svc.
