WAI-ARIA Support

This article demonstrates how you can take advantage of the WAI-ARIA support of the RadMenu. The WAI-ARIA Suite defines an approach to make Web content and Web applications more accessible to people with disabilities. In order to enable the WAI-ARIA support, set the EnableAriaSupport property of RadMenu to true as shown in the example below.

Example 1: Setting EnalbeAriaSupport property for RadMenu.

<telerik:RadMenu RenderMode="Lightweight" ID="RadMenu1" runat="server" EnableAriaSupport="true">
    <Items>
        <telerik:RadMenuItem runat="server" Text="Root RadMenuItem1">
            <Items>
                <telerik:RadMenuItem runat="server" Text="Child RadMenuItem1">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem runat="server" Text="Child RadMenuItem2">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadMenuItem>
        <telerik:RadMenuItem runat="server" Text="Root RadMenuItem2">
            <Items>
                <telerik:RadMenuItem runat="server" Text="Child RadMenuItem1">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem runat="server" Text="Child RadMenuItem2">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadMenuItem>
    </Items>
</telerik:RadMenu>
protected void Page_Load(object sender, EventArgs e)
{
    RadMenu1.EnableAriaSupport = true;
}
Protected Sub Page_Load(sender As Object, e As EventArgs)
    RadMenu1.EnableAriaSupport = True
End Sub
note

The implementation of the WAI-ARIA support is achieved entirely 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.

note

In IE by default JAWS focuses the parent items and returns "Your browser does not support inline frames or is currently configured not to display them." This is caused by rendered iframes in the rmSlide element of the RadMenu parent item. In order to overcome this behavior you can set EnableOverlay="false" (which will prevent the iframe from being rendering). The same is valid for the RadContextMenu.
