Blazor RadioGroup Accessibility

Out of the box, the Telerik UI for Blazor RadioGroup provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.

The RadioGroup is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.


This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.

Selector Attribute Usage
.k-radio-list role=radiogroup Announces the radiogroup role of the element.
.k-radio-item role=none Due to issues with nested items, forces a no-role state.
.k-radio readonly or aria-readonly The attribute is rendered only when the radio button is read-only.
aria-invalid=true The attribute is rendered only when the radio button is in a form HTML element and announces the invalid state of the component.
.k-disabled > .k-radio disabled or aria-disabled The attribute is rendered only when the radio button is disabled.
