Agenda view in .NET MAUI Scheduler (SfScheduler)

19 Apr 202214 minutes to read

The agenda view displays the events or appointments (normal appointments, all-day appointments, recurring appointments, and span appointments) in chronological order, grouped by date between the minimum and maximum dates and the current date displayed by default. When the AppointmentsSource property of SfScheduler is null, the agenda view will show only the month, week, and date headers for mobile view and responsive UI, and for desktop UI it will display only the date header of display date.

A agenda view displays different UI for mobile and desktop, for mobile it displays the month header, the week header, and the date header, whereas for desktop, it displays the appointment only.

NOTE

When the desktop view width is less than 600, the scheduler will display the mobile agenda UI on the desktop.

<scheduler:SfScheduler  x:Name="Scheduler" 
                        View="Agenda">
</scheduler:SfScheduler>
this.Scheduler.View = SchedulerView.Agenda;
// Creating an instance for the scheduler appointment collection.
var appointments = new ObservableCollection<SchedulerAppointment>();
// Adding scheduler appointment in the scheduler appointment collection.
appointments.Add(new SchedulerAppointment()
{
    Subject = "Meeting",
    StartTime = DateTime.Now,
    EndTime = DateTime.Now.AddHours(1),
    Background = Brush.Orange,
});
// Adding scheduler appointment into the AppointmentsSource.
this.Scheduler.AppointmentsSource = appointments;

Month header appearance customization

The agenda month header view can be customized by using the MonthHeaderSettings property of AgendaView in the SfScheduler.

Customize month header appearance using style

You can style the date format, height, text style, and background color by using the properties such as DateFormat, Height, TextStyle, and Background properties of MonthHeaderSettings.

<scheduler:SfScheduler x:Name="Scheduler"
                        View="Agenda">
    <scheduler:SfScheduler.AgendaView>
        <scheduler:SchedulerAgendaView>
            <scheduler:SchedulerAgendaView.MonthHeaderSettings>
                <scheduler:SchedulerMonthHeaderSettings DateFormat="MMM yyy"
                                                        Height="200"
                                                        Background="LightGreen" />
            </scheduler:SchedulerAgendaView.MonthHeaderSettings>
        </scheduler:SchedulerAgendaView>
    </scheduler:SfScheduler.AgendaView>
 </scheduler:SfScheduler>
this.Scheduler.View = SchedulerView.Agenda;
var textStyle = new SchedulerTextStyle()
{
    TextColor = Colors.Red,
    FontSize = 25,
};

this.Scheduler.AgendaView.MonthHeaderSettings.DateFormat = "MMM yyy";
this.Scheduler.AgendaView.MonthHeaderSettings.Height = 200;
this.Scheduler.AgendaView.MonthHeaderSettings.TextStyle = textStyle;
this.Scheduler.AgendaView.MonthHeaderSettings.Background = Brush.LightGreen;

    <scheduler:SfScheduler.AgendaView>
        <scheduler:SchedulerAgendaView>
            <scheduler:SchedulerAgendaView.MonthHeaderTemplate>
                <DataTemplate>
                    <Grid>
                        <Label x:Name="label" HorizontalOptions="Center" Background="LightGreen" VerticalOptions="Center" TextColor="Black" FontSize="25"  Text="{Binding StringFormat='{0:MMMM yyyy}'}" />
                    </Grid>
                </DataTemplate>
            </scheduler:SchedulerAgendaView.MonthHeaderTemplate>
        </scheduler:SchedulerAgendaView>

Customize month header appearance using DataTemplateSelector

You can customize the month header appearance by using the MonthHeaderTemplate property of AgendaView in the SfScheduler. The DataTemplateSelector can choose a DataTemplate at runtime based on the value of a data-bound to month header by using the MonthHeaderTemplate. It allows you to choose a different data template for each month header, as well as customize the appearance of a particular month header based on certain conditions.

<Grid>
    <Grid.Resources>
        <DataTemplate x:Key="todayDateTemplate">
            <Grid>
                <Label x:Name="label" HorizontalOptions="Center" Background="MediumPurple" VerticalOptions="Center" TextColor="Yellow" FontSize="25"  Text="{Binding StringFormat='{0:MMMM yyyy}'}" />
            </Grid>
        </DataTemplate>
        <DataTemplate x:Key="normalDateTemplate">
            <Grid>
                <Label x:Name="label" HorizontalOptions="Center" Background="MediumPurple" VerticalOptions="Center" TextColor="White" FontSize="25"  Text="{Binding StringFormat='{0:MMMM yyyy}'}" />
            </Grid>
        </DataTemplate>
        <local:AgendaViewTemplateSelector x:Key="agendaViewTemplateSelector" TodayDateTemplate="{StaticResource todayDateTemplate}" NormalDateTemplate="{StaticResource normalDateTemplate}"/>
    </Grid.Resources>
    <scheduler:SfScheduler x:Name="Scheduler" 
                           View="Agenda" >
        <scheduler:SfScheduler.AgendaView>
            <scheduler:SchedulerAgendaView MonthHeaderTemplate="{StaticResource agendaViewTemplateSelector}" />
        </scheduler:SfScheduler.AgendaView>
    </scheduler:SfScheduler>
 </Grid>
public class AgendaViewTemplateSelector : DataTemplateSelector
{
    public AgendaViewTemplateSelector()
    {
    }
    public DataTemplate NormalDateTemplate { get; set; }
    public DataTemplate TodayDateTemplate { get; set; }
    protected override DataTemplate OnSelectTemplate(object item, BindableObject container)
    {
        var dateTime = (DateTime)item;
        if (dateTime.Month == DateTime.Today.Month)
            return TodayDateTemplate;
        else
            return NormalDateTemplate;
    }
}
this.Scheduler.View = SchedulerView.Agenda;

NOTE

  • The default value for DateFormat and Height are MMMM yyyy and 150, respectively.
  • For desktop UI, The agenda view displays the appointment only.
  • When using data template selector, performance issues occur as the conversion template views take time within the framework.
