RibbonBar / Accessibility

Accessibility validation

Validate with WAVE

WAVE is a free web accessibility evaluation tool, which checks for compliance issues with many of the Section 508 and WCAG guidelines. Have in mind that only humans can determine whether a web page is accessible - the above validation link is provided for the sake of completeness.


  • This example shows the accessibility features of RadRibbonBar for ASP.NET AJAX. RadRibbonBar has keyboard navigation enabled as well as tooltips for images with the ImageAltText property.

    Press ALt + R to activate the RibbonBar and show the key hints.

    The control is also visible in Windows High Contrast mode when using Simple skin.

    Telerik RadRibbonBar for ASP.NET AJAX is level A accessible (in compliance with the W3C Web Accessibility Guidelines 2.0) as well as Section 508 compliant.
