Appointment Template in DayView and MultiDayView

Appointment Template Overview

Appointment Template Example

The following example shows how to set AppointmentContentTemplate in DayView Mode using DataTemplateSelector.

First, create a ViewModel class with a collection of Appointment objects:

public class AppointmentsTemplateViewModel
    public AppointmentsTemplateViewModel()
        var date = DateTime.Today;
        this.Appointments = new ObservableCollection<Appointment>
            new Appointment{ Title = "Tom Birthday", IsAllDay = true, Color = Color.FromHex("#C1D8FF"), Detail ="Buy present!", StartDate = date, EndDate = date.AddHours(12)},
            new Appointment{ Title = "Lunch with Sara", IsAllDay = false, Color = Color.FromHex("#EDFDE3"), Detail ="Discuss the new marketing strategy", StartDate = date.AddDays(1).AddHours(12), EndDate = date.AddDays(1).AddHours(13).AddMinutes(30)},
            new Appointment{ Title = "Security Training", IsAllDay = false, Color = Color.FromHex("#EDFDE3"), Detail ="Details for the event come here", StartDate = date.AddHours(15), EndDate = date.AddHours(16)},
            new Appointment{ Title = "Elle Birthday", IsAllDay = true, Color = Color.FromHex("#FFF1F9"), Detail ="Buy present!", StartDate = date.AddDays(1), EndDate = date.AddDays(1).AddHours(12)},
            new Appointment{ Title = "One to One Meeting", IsAllDay = false, Color = Color.FromHex("#EBF2FD"), Detail ="Details for the event come here - for example place, participants and add information", StartDate = date.AddHours(16), EndDate = date.AddHours(17)},
            new Appointment{ Title = "Marathon", IsAllDay = false, Color = Color.FromHex("#FDE2AC"), Detail ="Enjoy running", StartDate = date.AddHours(8), EndDate = date.AddHours(11)},
    public ObservableCollection<Appointment> Appointments { get; set; }

Create a custom appointment template selector class which inherits from DataTemplateSelector and override the OnSelectTemplate method:

public class DayViewAppointmentTemplateSelector : DataTemplateSelector
    public DataTemplate AllDay { get; set; }
    public DataTemplate NotAllDay { get; set; }

    protected override DataTemplate OnSelectTemplate(object item, BindableObject container)
        var appointmentsTemplate = item as Appointment;

        if (appointmentsTemplate.IsAllDay)
            return this.AllDay;
        return this.NotAllDay;

Add the created DayViewAppointmentTemplateSelector as a Resource and define both DataTemplates:

<local:DayViewAppointmentTemplateSelector x:Key="DayViewAppointmentTemplateSelector">
                <Label Text="{Binding Title}" FontSize="16" TextColor="Black"/>
                    <Label Text="{Binding Title}" FontSize="20" TextColor="Black"/>
                    <Label Text="{Binding Detail}" FontSize="14" TextColor="Black"/>
                <Image Source="favourite.png" VerticalOptions="Center" HorizontalOptions="Center" Grid.Column="1"/>

Finally, set the AppointmentContentTemplate property of the DayViewSettings:

<telerikInput:RadCalendar x:Name="calendar"
                          AppointmentsSource="{Binding Appointments}"
        <telerikInput:DayViewSettings AppointmentContentTemplate="{StaticResource DayViewAppointmentTemplateSelector}"/>

Here is the result:

Appointment Content Template
