Validate with WAVE

RadInput is compliant with Section 508 and Level AA of the WCAG 2.0 Guidelines. Run WAVE, the automated web accessibility evaluation tool, to check the accessibility level of the control yourself.

This example demonstrates how you can make Telerik ASP.NET RadInput accessible by leveraging the settings for the different caption and summary properties of the rendered HTML elements.
