We are developing a system support disable people. We use Rad controls: RadGridView, RadExpander, RadOutlookBar, RadDateTimePicker, RadTimePicker, Calendar, RadCombo box. So, the question is: How do controls support accessibility?
The truth is that we have not performed enough tests for W3C WCAG 2.0 AA compliance. Due to the dynamic evolution of Silverlight since its very beginning we were entirely focused on catching up with the new stuff and taking advantage of the new features. While we were performing such tests with the previous versions of Silverlight, when our controls were natively built on them, once we migrated to Silverlight 4 we haven't had the time to do intensive testing for W3C WCAG 2.0 AA compliance. Therefore, to provide a more certain answer we will need some time do investigate the matter.
Another aspect to consider would be that Silverlight controls in general can be W3C WCAG 2.0 AA compliant in terms of Windows Accessibility because Silverlight applications are more like Windows application rather then web apps.
I hope that this reply is acceptable for you and you will be willing to wait for a more details coming soon.
