Hi, Our Accessibility partner while evaluating our product for 508 compliance we got one report saying RadGrid control is not accessible. We do have enablearia attribute on the radgrid and is emitting the aria-attributes as mentioned in your demo. http://demos.telerik.com/aspnet-ajax/grid/examples/accessibility-and-internationalization/wai-aria-support/defaultcs.aspx As per them : "So it does not alert the user that arrow keys may be used to navigate it". I have attached a snippet of their report regarding radgrid accessibility. Can you please let me know if anything is missing. Thanks and best regards, Mirang
