React Lookup - OData Service

Use the ODataStore to bind the Lookup to data provided by an OData service.

jQuery
JavaScript
$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: new DevExpress.data.ODataStore({
            url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
            key: "Product_ID"
        }),
        valueExpr: "Product_Cost",
        displayExpr: "Product_Name"
    });
});
Angular
HTML
TypeScript
<dx-lookup
    [dataSource]="lookupDataSource"
    valueExpr="Product_Cost"
    displayExpr="Product_Name">
</dx-lookup>
import { DxLookupModule } from "devextreme-angular";
import ODataStore from "devextreme/data/odata/store";
// ...
export class AppComponent {
    lookupDataSource = new ODataStore({
        url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
        key: "Product_ID"
    });
}
@NgModule({
    imports: [
        // ...
        DxLookupModule
    ],
    // ...
})
Vue
<template>
    <DxLookup
        :data-source="products"
        value-expr="Product_Cost"
        display-expr="Product_Name"
    />
</template>

<script>
import 'devextreme/dist/css/dx.light.css';

import { DxLookup } from 'devextreme-vue/lookup';
import ODataStore from "devextreme/data/odata/store";

export default {
    components: {
        DxLookup
    },
    data() {
        return {
            products: new ODataStore({
                url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
                key: "Product_ID"
            })
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import { Lookup } from 'devextreme-react/lookup';
import ODataStore from "devextreme/data/odata/store";

class App extends React.Component {
    constructor(props) {
        super(props);

        this.products = new ODataStore({
            url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
            key: "Product_ID"
        });
    }

    render() {
        return (
            <Lookup
                dataSource={this.products}
                valueExpr="Product_Cost"
                displayExpr="Product_Name"
            />
        );
    }
}

export default App;

Data kept in the ODataStore can be processed in a DataSource. For example, the DataSource can filter data.

jQuery
JavaScript
$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: new DevExpress.data.DataSource({
            store: {
                type: "odata",
                url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
                key: "Product_ID"
            },
            filter: ["Product_Available", "=", true]
        }),
        valueExpr: "Product_Cost",
        displayExpr: "Product_Name"
    });
});

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

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.
