The ProgressButton component triggers events based on its actions. The events can be used as extension points to perform custom operations.

The events available in ProgressButton are fail, begin, progress, and end.

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { ProgressEventArgs } from '@syncfusion/ej2-angular-splitbuttons';

@Component({
    selector: 'app-root',
    template: `
    <div class="control-section">
    <div class="progress-btn-section">
        <button ejs-progressbutton content='Progress' [enableProgress]='true' (begin)='begin($event)' (end)='end($event)' (progress)='progress($event)' (fail)='fail($event)' cssClass='e-hide-spinner'></button>
    </div>
    <div class="property-section">
        <table id="propertyTable" title="Event trace">
            <tbody>
                <th>Event trace:-</th>
                <tr>
                <td [innerHTML]="eventTrace"></td>
                </tr>
            </tbody>
        </table>
    </div>
    <button #clear id="clear" ejs-button cssClass='e-small' (click)='btnClick()'>Clear</button>
    </div>
    `
})

export class AppComponent {
    private eventTrace: string = '';
    @ViewChild('clear')

    private begin(args: ProgressEventArgs): void {
        this.updateEventLog(args);
    }
    private end(args: ProgressEventArgs): void {
        this.updateEventLog(args);
    }
    private progress(args: ProgressEventArgs): void {
        this.updateEventLog(args);
    }
    private fail(args: Event): void {
        this.updateEventLog(args);
    }
    private updateEventLog(args: any): void {
        this.eventTrace = this.eventTrace + args.name + ' Event triggered. <br />'
    }

    private btnClick(): void {
        this.eventTrace = '';
    }
}
