OData Service

Use the ODataStore to bind SelectBox to data an OData service provides.

jQuery
JavaScript
$(function() {
    $("#selectBoxContainer").dxSelectBox({
        dataSource: new DevExpress.data.ODataStore({
            url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
            key: "Product_ID"
        }),
        valueExpr: "Product_Cost",
        displayExpr: "Product_Name"
    });
});
Angular
TypeScript
HTML
import ODataStore from 'devextreme/data/odata/store';
import { DxSelectBoxModule } from 'devextreme-angular';
// ...
export class AppComponent {
    productStore = new ODataStore({
        url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
        key: "Product_ID"
    });
}
@NgModule({
     imports: [
         // ...
         DxSelectBoxModule
     ],
     // ...
 })
<dx-select-box
    [dataSource]="productStore"
    valueExpr="Product_Cost"
    displayExpr="Product_Name">
</dx-select-box>

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

jQuery
JavaScript
$(function() {
    $("#selectBoxContainer").dxSelectBox({
        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"
    });
});
Angular

HTML
import 'devextreme/data/odata/store';
import DataSource from 'devextreme/data/data_source';
import { DxSelectBoxModule } from 'devextreme-angular';
// ...
export class AppComponent {
    productStore = new DataSource({
        store: {
            type: "odata",
            url: "https://js.devexpress.com/Demos/DevAV/odata/Products",
            key: "Product_ID"
        },
        filter: ["Product_Available", "=", true]
    });
}
@NgModule({
     imports: [
         // ...
         DxSelectBoxModule
     ],
     // ...
 })
<dx-select-box
    [dataSource]="productStore"
    valueExpr="Product_Cost"
    displayExpr="Product_Name">
</dx-select-box>
