    Following the online demos for Binding to Generic Lists and Defining Resources as a guide, I have attempted to use resources to style my appointments. 

    After running DataBind(), I can see that each Appointment has a resource but when the scheduler loads up, the styles are not taking effect. When I look at the page's html source, the appointment element has class="rsApt " (notice the space), not class="rsApt User".

    The Defining Resources example source shows class="rsApt Alex" or Charlie or Bob.  The Binding to Generic List examples source shows the same thing that I am seeing.

    Is this a bug, or is this functionality that is not available when binding to generic lists?  Any Ideas?

    Hello Josh,

    The resource names are not automatically rendered as CSS classes. You should attach to the AppointmentCreated event and set them on the fly, as in the example:

    protected void RadScheduler1_AppointmentCreated(object sender, AppointmentCreatedEventArgs e) 
        foreach (Resource resource in e.Appointment.Resources) 
            if (resource.Type == "User"
                e.Appointment.CssClass = resource.Text;

    As indicated in the title, I'm filling in the RadScheduler with a list (List <MyType>) and there's no way to fill in the resources.
    I developed a parser to fill appointments but when i try to access to an appointment resource it crashes.
    This is the binding code:
    protected void Page_Init(object sender, EventArgs e)
             //List<CalendarAppointment> appointments = new List<CalendarAppointment>();
              List<Telerik.Web.UI.Appointment> appointments = new List<Telerik.Web.UI.Appointment>();
              appointments = ParsearAppointments(business.GetCalendarAppointments(calendar.Id));
             RadScheduler1.DataSource = appointments;
    and there is the parser:
    private List<Appointment> ParsearAppointments(List<CalendarAppointment> list)
        List<Appointment> appointments = new List<Appointment>();
        Telerik.Web.UI.Appointment a = new Telerik.Web.UI.Appointment();
        foreach (CalendarAppointment ap in list)
            //a.Resources[0].Key=ap.CalendarId;---> it crashes here
        return appointments;

    And the error code:

    {"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"}

    I would appreciate a way to fix this issue or another way to do this.

    It seems that the problem is caused by an empty resource collection for your appointment. In order to avoid that behavior I would suggest adding a resource to that item using the following expression:
    //code behind
    a.Resources.Add(new Resource(....));

    Once you have a resource item added to the appointment resource collection, you will be able to access it by index.
