I'm following your resource filtering demo here (http://demos.telerik.com/aspnet-ajax/scheduler/examples/resources/defaultcs.aspx
) with the latest controls (2011.3.1324.40). The only difference between my code and yours is that I'm binding to a list of objects in my Page_Init and you are binding to a datasource control. Also, your filter controls autopostback, but mine require the user to click an "Apply Filters" button. The click event for the button does the same thing though, it calls ReBind() on the RadScheduler control. Sure enough, I see the DataBound event fire, but the AppointmentDataBound events never do. That's where your code (and mine, by extension) hides certain appointments based on the filters selected, so it kind of needs to be firing on Rebind. Any ideas what would prevent that event from firing?
