Special Slots

The Telerik UI for .NET MAUI Scheduler control exposes an option to define the special and read-only slots and apply different styles to them. You need to prepare a collection of Slot objects and assign it to the SpecialSlotsSource property of the corresponding view definition.

Every Slot has the following properties:

• Start(DateTime)—Defines the start date of the slot.
• End(DateTime)—Defines the end date of the slot.
• ReccurencePattern(RecurrencePattern)—Defines whether the slot will be displayed for repeating days.
• IsReadOnly(bool)—When set to True the slot is disabled.
• TimeZone(TimeZoneInfo)—Specifies the slot time zone.

Below you can find a quick example how to create special slots.

1. First, create a ViewModel class with a collection of Slot objects. In the example two repeating slots are added for rest hours during weekdays.

• C#

public class ViewModel
{
    public ViewModel()
    {
        this.RestHours = new ObservableCollection<Slot>();

        var today = DateTime.Today;
        var dailyRecurrence = new RecurrencePattern()
        {
            DaysOfWeekMask = RecurrenceDays.WeekDays,
            Frequency = RecurrenceFrequency.Weekly,
            MaxOccurrences = 30
        };

        this.RestHours.Add(new Slot(today.AddHours(12), today.AddHours(13))
        {
            RecurrencePattern = dailyRecurrence,
            IsReadOnly = true
        });

        this.RestHours.Add(new Slot(today.AddHours(16), today.AddHours(16).AddMinutes(15))
        {
            RecurrencePattern = dailyRecurrence
        });
    }

    public ObservableCollection<Slot> RestHours { get; set; }
}

2. Then, add RadScheduler definition with some sample views with SpecialSource property applied:

• XAML

<telerik:RadScheduler x:Name="scheduler">
    <telerik:RadScheduler.ViewDefinitions>
        <telerik:DayViewDefinition SpecialSlotsSource="{Binding RestHours}" />
        <telerik:MultidayViewDefinition VisibleDays="3" Title="3 Day" SpecialSlotsSource="{Binding RestHours}" />
    </telerik:RadScheduler.ViewDefinitions>
</telerik:RadScheduler>

3. Last step is to set the BindingContext to the ViewModel class:

• C#

this.BindingContext = new ViewModel();
