Load tab with data source in Angular Tab component

1 Dec 20223 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, ODataAdaptor, ReturnOption } from '@syncfusion/ej2-data';

const SERVICE_URI: string = 'https://js.syncfusion.com/ejServices/Wcf/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 ODataAdaptor})
        .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.items = this.itemsData;
            this.tabObj.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';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
