We are currently in the process of renewing the embedded icons of RadButton. That's why the demo is redirecting to the help article in our documentation. If you have any questions on the help article
itself please do not hesitate to contact us. We will restore back the embedded icons demo shortly as soon as we are ready with the icons improvements.
Thanks for your understanding.
If you want to get updates on new releases, tips and tricks and sneak peeks at our product labs directly from the developers working on the RadControls for ASP.NET AJAX, subscribe to the blog feed
