How to add font awesome icon in appointment subject without losing the existing (default) style.
My Radscheduler is binded with Dataset code is below.

--------------------------aspx------------------------------------------
<telerik:RadScheduler OnClientAppointmentClick="OnClientAppointmentClick" OnAppointmentDataBound="RadScheduler1_AppointmentDataBound" CustomAttributeNames="SiteId,UserId" ReadOnly="true" runat="server" ID="RadScheduler1" SelectedView="MonthView" OverflowBehavior="Auto">                    
                    </telerik:RadScheduler>
-------------------------aspx.cs---------------------------------------
RadScheduler1.DataSource = ds;//Dataset
RadScheduler1.DataKeyField = "ScheduleID";
RadScheduler1.DataStartField = "ScheduleDate";
RadScheduler1.DataEndField = "ScheduleDate";
RadScheduler1.DataSubjectField = "Name";// at this stage I want add awesome font if CustomAttributeNames    UserId is not null. this field also available in ds
RadScheduler1.DataBind();

protected void RadScheduler1_AppointmentDataBound(object sender, Telerik.Web.UI.SchedulerEventArgs e)
{
DataRowView row = (DataRowView)e.Appointment.DataItem;
e.Appointment.Attributes.Add("SiteId", row["SiteId"].ToString());
e.Appointment.Attributes.Add("UserId", row["UserId"].ToString());
}

CORRECTION to above code....

Hello,

Using the appointment templates would be possible solution if you want to add an icon or image in the appointment container. Here you can find a demo that demonstrates how to use the appointment templates in real scenario.
