Angular Lookup - Array Only

Bind the Lookup to an array by passing it to the dataSource property. The array may contain primitive values...

jQuery
JavaScript
const products = ["HD Video Player", "SuperHD Video Player", "SuperPlasma 50", "SuperLED 50"];

$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: products
    });
});

// ...
export class AppComponent {
    lookupDataSource = ["HD Video Player", "SuperHD Video Player", "SuperPlasma 50", "SuperLED 50"];
}

You can create a Query if objects in an array need to be processed (sorted, filtered, grouped, etc.). For example, in the following code, a Query sorts objects in the products array by the price field in descending order:

jQuery
JavaScript
const products = [
        { name: "HD Video Player", price: 100 },
        // ...
    ];

    $(function() {
        $("#lookupContainer").dxLookup({
            dataSource: DevExpress.data.query(products)
                            .sortBy("price", true)
                            .toArray(),
            valueExpr: 'price',
            displayExpr: 'name'
        });
    });
Angular
HTML
TypeScript
<dx-lookup
    [dataSource]="getSortedProducts()"
    valueExpr="price"
    displayExpr="name">
</dx-lookup>
import { DxLookupModule } from "devextreme-angular";
import query from "devextreme/data/query";
// ...
export class AppComponent {
    products = [
        { name: "HD Video Player", price: 100 },
        // ...
    ];
    getSortedProducts () {
        return query(this.products)
                .sortBy("price", true)
                .toArray();
    }
}

    imports: [
        // ...
