Screen Reader Support

The ProgressBar component supports screen readers and complies to WAI-ARIA standards.

To improve accessibility, use the elementAttr property to specify aria-label for the component.

Not all screen readers pronounce the progress status. To make sure the status is pronounced, add the following aria-* attributes:

app.component.html
app.component.ts
  • <dx-progress-bar
  • [elementAttr]="elementAttr"
  • (onContentReady)="onContentReady($event)"
  • >
  • </dx-progress-bar>
  • export class AppComponent {
  • elementAttr = {
  • 'aria-live': 'polite',
  • 'aria-describedby': 'status'
  • };
  • onContentReady: ({ element }) => {
  • element.querySelector('.dx-progressbar-status').setAttribute('id', 'status');
  • }
  • }
