You can configure ODataStore as a standalone element (see OData for details), but this demo assigns ODataStore settings to the store field of the DataSource configuration object. If you follow the same pattern in your application, make sure to set the store's type property to "odata".
If you target .NET for your backend API, be sure to check out Web API Service and register your free copy today. The Solution Wizard scaffolds an OData v4 Web API Service (.NET 6+) with integrated authorization & CRUD operations powered by EF Core and our XPO ORM library. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing.
The built-in Web API Service also filters out secured server data based on permissions granted to users. Advanced/enterprise functions include audit trail, endpoints to download reports, file attachments, check validation, obtain localized captions, etc.
To use the free Solution Wizard (which creates the Web API Service) run the Universal Component Installer from the DevExpress Download Manager.
