This example shows the accessibility features of RadScheduler for ASP.NET AJAX. RadScheduler has keyboard navigation enabled. By default RadScheduler requires TabIndex to be set. One can also utlize AccessKey. For the purpose of this demo, the access key of RadScheduler is set to 'F'.

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