With the new SP1 release of Q3 2010 we added a new feature to RadScheduleView that helps you customize every slot in a different way.custom slots

To do that you should create an instance of the Slot class, set its Start and  End  properties,

the Resources property - with this property you can define in which resource column the slot will be displayed,

and the RecurrencePattern property - with this property you can define whether the slot will be displayed for repeating days or events like Christmas, WeekendDays  and Birthdays.

For example let's say that we have a schedule control and want to customize the days that are holidays.

To do that we create slots for Christmas, Saint Valentine and Halloween days:
var christmasSlot = new Slot() { Start = new DateTime(2010, 12, 25), End = new DateTime(2010, 12, 26) };
            christmasSlot.RecurrencePattern = new RecurrencePattern();
            christmasSlot.RecurrencePattern.Interval = 1;
            christmasSlot.RecurrencePattern.Frequency = RecurrenceFrequency.Yearly;
            christmasSlot.RecurrencePattern.DayOfMonth = 25;
            christmasSlot.RecurrencePattern.MonthOfYear = 12;
            var valentineSlot = new Slot() { Start = new DateTime(2010, 2, 14), End = new DateTime(2010, 2, 15) };
            valentineSlot.RecurrencePattern = new RecurrencePattern();
            valentineSlot.RecurrencePattern.Interval = 1;
            valentineSlot.RecurrencePattern.Frequency = RecurrenceFrequency.Yearly;
            valentineSlot.RecurrencePattern.DayOfMonth = 14;
            valentineSlot.RecurrencePattern.MonthOfYear = 2;

When we are ready we should add the slots to the SpecialSlotsSource property of the control.

 The only thing left is to assign a style for Christmas, Halloween and St.Valentine. RadScheduleView has SpecialSlotsStyleSelector property that we will use for this task:

<telerik:RadScheduleView Grid.Column="1" Grid.Row="0"
                             SpecialSlotsSource="{Binding SpecialSlots}"
                             AppointmentsSource="{Binding Appointments}"
                             SpecialSlotStyleSelector="{StaticResource HolidayStyleSelector}"
                             Margin="10 0 10 0">
            <telerik:MonthViewDefinition />
