WAI-ARIA Support
This article demonstrates how to enable and use the WAI-ARIA support of the RadRadioButtonList control.
The WAI-ARIA Suite defines an approach to make web content and web applications more accessible to people with disabilities. RadRadioButtonList offers WAI-ARIA support.
In order to enable the WAI-ARIA support, set the RadRadioButtonList control's EnableAriaSupport property to true and, optionally, set the inner properties (DescribedBy and Label) of the AriaSettings composite tag to the desired values as shown in Example 1.
Example 1: Enabling WAI-ARIA support for RadRadioButtonList
<telerik:RadRadioButtonList runat="server" ID="RadRadioButtonList1" EnableAriaSupport="true">
<Items>
<telerik:RadioButtonListItem Text="English" Selected="true" />
<telerik:RadioButtonListItem Text="German" />
<telerik:RadioButtonListItem Text="French" />
</Items>
</telerik:RadRadioButtonList>
The implementation of the WAI-ARIA support is achieved entirely on the client side (using JavaScript) by appending different attributes and appropriate WAI-ARIA roles to the DOM elements. This is done because an HTML document containing ARIA attributes will not pass validation if they are added on the server.
