Save 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 steps explain the State Maintenance in the ProgressBar control.

In the HTML page, add a <div> element to render the ProgressBar widget.

  • HTML
  • <div class="control">
        <div id="progressbar"></div>
  • // Add the following script to enable State Maintenance.
    /// <reference path="tsfiles/jquery.d.ts" />
    /// <reference path="tsfiles/ej.web.all.d.ts" />
    module ProgressBarComponent {
        $(function () {
            var sample = new ej.ProgressBar($("#progressbar"),{
                enablePersistence: true,
                value: 40,
                width: 500,
                height: 40
            sample.setModel({ text: progress.getValue() + " %" });

    The following screenshot displays the output.
