WAI-ARIA Support

The RadToggleButton control has WAI-ARIA support which can be easily enabled by setting its EnableAriaSupport property to true.

The WAI-ARIA attributes are rendered with JavaScript because no HTML document can validate if they are present in the server markup. Therefore, in order to see them, you should inspect the control with the browser dev toolbar and not the page source.
