    Using methods and events

    This guide explains how to use Flexmonster methods and events in an Angular application. First, we will create a reference to the Flexmonster instance. Then we will use this reference to call methods and subscribe to events.


    • An Angular application with Flexmonster embedded into it.
      If Flexmonster is not yet embedded, see Integration with Angular.

    Create a reference to the <fm-pivot> instance

    To access Flexmonster API inside the .component.ts file, a reference to the <fm-pivot> instance is needed. Follow the steps below to create the reference using the @ViewChild decorator:

    Step 1. In the HTML template of the component with Flexmonster (e.g., src/app/app.component.html), assign a template reference variable to the <fm-pivot> instance (e.g., #pivot):

    <fm-pivot #pivot

    Step 2. In the component’s TypeScript file (e.g., src/app/app.component.ts), import the @ViewChild decorator:

    import { Component, ViewChild } from '@angular/core';

    Step 3. In the same TypeScript file, import FlexmonsterPivot from ng-flexmonster:

    import { FlexmonsterPivot } from 'ng-flexmonster';

    Step 4. In the same TypeScript file, use @ViewChild to inject a reference to the <fm-pivot> instance (e.g., pivotRef):

    @ViewChild('pivot') pivotRef!: FlexmonsterPivot;

    pivot is the template reference variable assigned to the <fm-pivot> instance in step 1.

    The full code from steps 2-4 should look similar to the following:

    import { Component, ViewChild } from '@angular/core';
    import { FlexmonsterPivot } from 'ng-flexmonster';
    	selector: 'app-root',
    	templateUrl: './app.component.html',
    	styleUrls: ['./app.component.css'],
    export class AppComponent {
    	@ViewChild('pivot') pivotRef!: FlexmonsterPivot;
    	// other code

    The pivotRef reference can now be used to access methods and events of the <fm-pivot> instance.

    Use methods

    Call Flexmonster methods using the previously created pivotRef reference:


    Check out the sample Angular project for more examples of methods usage.

    See the full list of Flexmonster methods.

    Use events

    There are two ways to subscribe to events:

    You can also unsubscribe from an event.

    Subscribing to events via the <fm-pivot> attributes

    Define the event as the <fm-pivot> attribute and assign an event handler to it:


    The sample Angular project demonstrates how to subscribe to events via the directive’s attributes.

    See the full list of Flexmonster events.

    Subscribing to events via the on() method

    Use the previously created pivotRef reference to call the on() method:

    this.pivotRef.flexmonster.on('reportcomplete', onReportComplete);

    See how the on() method is used in the sample Angular project.

    Check out the full list of Flexmonster events.

    Unsubscribing from events

    Use the off() method to unsubscribe from an event:'reportcomplete');

    See how the off() method is used in the sample Angular project.
