During the Beta of RadControls for ASP.NET AJAX, the client-side API was in a transition period using a compatibility layer to support both ASP.NET AJAX naming conventions and our older naming conventions. Since the suite is no longer in Beta, the compatibility layer was removed and the client-side APIs strictly follow the ASP.NET AJAX conventions.
This includes capitalization of methods. For instance: .AjaxRequest()
should become .set_mode()
. The ASP.NET AJAX conventions also include get_/set_ methods for properties. This means that in your case eventArgs.get_resource().key; should become eventArgs.get_resource().get_key;
