ImageButton - WAI-ARIA Support

Isolate this demo as a stand-alone application
  • About this demo
  • C#
  • VB

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

According to the WAI-ARIA specifications for image buttons, when Text is set, it is set as the title attribute of the image button.

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.
