Blazor DateInput Accessibility

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

The DateInput 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.

WAI-ARIA

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

Selector Attribute Usage
.k-input-inner role=textbox or nodeName=input The element should either be an <input type="text"> element or should have role="textbox" assigned.
label for or aria-label or aria-labelledby The input needs an accessible name to be assigned to it.
aria-required=true The attribute is rendered only when the DateInput is in a form HTML element and announces the required state of the component.
aria-invalid=true Attribute is rendered only when the DateInput is in form and announces the valid state of the component.
aria-describedby=.k-form-hint id/.k-form-error id Points to the hint for the input, or if the input is invalid, to the error message. This attribute should only be present when a hint is set or when the input is invalid.
readonly=readonly or aria-readonly=true Attribute is rendered only when the DateInput is readonly.
tabindex=0 The element should be focusable.
.k-disabled .k-input-inner disabled=disabled or aria-disabled=true Attribute is rendered only when the DateInput is disabled.
