Load tab with data source in Angular Tab component

28 Sep 20233 minutes to read

You can bind any data object to Tab items, by mapping it to header and content  property.

You can watch the following video to learn more about loading tab items from a remote data source in the Angular Tabs component:

In the below demo, Data is fetched from an OData service using DataManager. The result data is formatted as a JSON object with header and content fields, which is set to items property of Tab.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { TabComponent } from '@syncfusion/ej2-angular-navigations';
import { DataManager, Query, ODataV4Adaptor, ReturnOption } from '@syncfusion/ej2-data';

const SERVICE_URI: string = 'https://services.odata.org/V4/Northwind/Northwind.svc/Employees';

/**
 * Load tab with DataSource
 */

@Component({
    selector: 'app-container',
    template: `<ejs-tab #tab></ejs-tab>`
})
export class AppComponent implements OnInit {
    @ViewChild('tab') tabObj?: TabComponent;
    public itemsData: any = [];
    public mapping =  { header: 'FirstName', content: 'Notes' };

    public ngOnInit(): void {
        new DataManager({ url: SERVICE_URI, adaptor: new ODataV4Adaptor})
        .executeQuery(new Query().range(1, 4)).then((e: ReturnOption) => {
            let result: any = e.result;

            for(let i: number = 0; i < result.length; i++) {
                this.itemsData.push({ header: {text: result[i][this.mapping.header]}, content: result[i][this.mapping.content] });
            }
            (this.tabObj as TabComponent).items = this.itemsData;
            (this.tabObj as TabComponent).dataBind();
        });
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { TabModule } from '@syncfusion/ej2-angular-navigations';
/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, FormsModule, TabModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
