Accessibility Standards Compliance

The ProgressBar component complies to all Section 508 and WCAG 2.x standards criteria.

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:

jQuery
index.js
$(function(){
    $("#progressBarContainer").dxProgressBar({
        elementAttr: {
            'aria-live': 'polite',
            'aria-describedby': 'status',
        },
        onContentReady: ({ element }) => {
            $(element).find('.dx-progressbar-status').attr('id', 'status');
        }
    });
});
Angular
app.component.html
app.component.ts
<dx-progress-bar
    [elementAttr]="elementAttr"
    (onContentReady)="onContentReady($event)"
>
</dx-progress-bar>
export class AppComponent {
    elementAttr = {
        'aria-live': 'polite',
        'aria-describedby': 'status'
    };
    onContentReady: ({ element }) => {
        element.querySelector('.dx-progressbar-status').setAttribute('id', 'status');
    }
}
Vue
App.vue
<template>
<DxProgressBar
    :element-attr="elementAttr"
    @on-content-ready="onContentReady"
/>
</template>

<script>
import { DxProgressBar } from 'devextreme-vue/progress-bar';

export default {
    components: {
        DxProgressBar,
    },
    data() {
        return {
            elementAttr: {
                'aria-live': 'polite',
                'aria-describedby': 'status',
            },
        };
    },
    methods: {
        onContentReady({ element }) {
            element.querySelector('.dx-progressbar-status').setAttribute('id', 'status');
        },
    },
};
</script>
React
App.js
import React from 'react';
import { ProgressBar } from 'devextreme-react/progress-bar';

function App() {
    const elementAttr = {
        'aria-live': 'polite',
        'aria-describedby': 'status',
    };

    const onContentReady = ({ element }) => {
        element.querySelector('.dx-progressbar-status').setAttribute('id', 'status');
    };

    return (
        <div>
            <ProgressBar
                elementAttr={elementAttr}
                onContentReady={onContentReady}
            />
        </div>
    );
