DevExtreme Angular - OData
NOTE
This article describes how to bind a DevExtreme widget to an OData service in jQuery, Angular, Vue, and React. For information on data binding in ASP.NET MVC Controls, refer to docs.devexpress.com.
To access an OData service, implement the ODataStore: specify the url of an OData entity collection, the key property, and the OData version. You can also handle data-related events:
app.component.ts
app.module.ts
app.component.html
- import { Component } from '@angular/core';
- import ODataStore from 'devextreme/data/odata/store';
- @Component({
- selector: 'app-root',
- templateUrl: './app.component.html',
- styleUrls: ['./app.component.css']
- })
- export class AppComponent {
- productsStore: ODataStore;
- constructor() {
- this.productsStore = new ODataStore({
- url: 'https://js.devexpress.com/Demos/DevAV/odata/Products',
- key: 'Product_ID',
- version: 3,
- onLoaded: () => {
- // Event handling commands go here
- }
- });
- }
- }
- import { BrowserModule } from '@angular/platform-browser';
- import { NgModule } from '@angular/core';
- import { AppComponent } from './app.component';
- import { DxDataGridModule } from 'devextreme-angular';
- @NgModule({
- declarations: [
- AppComponent
- ],
- imports: [
- BrowserModule,
- DxDataGridModule
- ],
- providers: [ ],
- bootstrap: [AppComponent]
- })
- export class AppModule { }
- <dx-data-grid
- [dataSource]="productsStore">
- </dx-data-grid>
Data from the ODataStore can be shaped (filtered, sorted, grouped, etc.) in the DataSource.
The following example declares an ODataStore, wraps it in a DataSource, and binds the DataGrid widget to this DataSource:
app.component.ts
app.module.ts
app.component.html
- import { Component } from '@angular/core';
- import ODataStore from 'devextreme/data/odata/store';
- import DataSource from 'devextreme/data/data_source';
- @Component({
- selector: 'app-root',
- templateUrl: './app.component.html',
- styleUrls: ['./app.component.css']
- })
- export class AppComponent {
- productsDataSource: DataSource;
- constructor() {
- const productsStore = new ODataStore({
- // ...
- });
- this.productsDataSource = new DataSource({
- store: productsStore,
- sort: 'Product_Name'
- });
- }
- }
- import { BrowserModule } from '@angular/platform-browser';
- import { NgModule } from '@angular/core';
- import { AppComponent } from './app.component';
- import { DxDataGridModule } from 'devextreme-angular';
- @NgModule({
- declarations: [
- AppComponent
- ],
- imports: [
- BrowserModule,
- DxDataGridModule
- ],
- providers: [ ],
- bootstrap: [AppComponent]
- })
- export class AppModule { }
- <dx-data-grid
- [dataSource]="productsDataSource">
- </dx-data-grid>
