State Maintenance

Saves current model value to cookies for State Maintenance. While refreshing the ProgressBar widget, page retains the model value applied from browser cookies. By default, the enablePersistence property is set to ‘false’ in the ProgressBar.

The following code enables the State Maintenance in the ProgressBar control.

  • html
  • <div class="control">
        <ej-progressbar id="progressBar" [enablePersistence]="true" [value]="val" [height]="height" [width]="width" (create)="onCreate($event)"></ej-progressbar>  
  • html
  • import {Component} from '@angular/core';
    selector: 'sd-home',
    templateUrl: 'app/components/progressbar/progressbar.component.html'
    export class ProgressBarComponent {  
        val: number;
        height: number;
        width: number;
        constructor() {
            this.val = 80;
            this.height = 20;
            this.width = 500;
        onCreate($event) {
            var progress = $("#progressBar").data("ejProgressBar");
            progress.setModel({ text: progress.getValue() });

    The following screenshot displays the output.
