DevExtreme jQuery - ODataStore API

The ODataStore is a store that provides an interface for loading and editing data from an individual OData entity collection and handling related events.

ASP.NET MVC Controls

Razor C#

Razor VB

@(Html.DevExtreme().WidgetName()
    .DataSource(ds => ds.OData()
        .Url("http://www.example.com/Northwind.svc/Products")
        .Key("ProductID")
        .KeyType(EdmType.Int32)
        // Other ODataStore properties go here
    )
)

@(Html.DevExtreme().WidgetName() _
    .DataSource(Function(ds)
        Return ds.OData() _
                 .Url("http://www.example.com/Northwind.svc/Products") _
                 .Key("ProductID") _
                 .KeyType(EdmType.Int32) _
                 @* ... *@
                 @* Other ODataStore properties go here *@
                 @* ... *@
    End Function)

To access an entire OData service, use the ODataContext instead.

NOTE

The ODataStore is immutable. You cannot change its configuration at runtime. However, you can use its methods to manipulate it.

A 1-Click Solution for CRUD Web API Services with Role-based Access Control via EF Core

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 ORM. 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 and use our predefined template in Visual Studio 2022+.
