How to add delete icon to each appointment of the WPF Scheduler (Calendar)

1 min read

In the WPF Scheduler, you can add the delete icon and remove the particular appointment by using that icon in the AppointmentTemplate.

XAML

Use the DataTemplate for the appointments and bind appointments to corresponding property.

<DataTemplate x:Key="appointmentTemplate">
    <Grid Background="{Binding Background}" HorizontalAlignment="Stretch">
        <Grid.RowDefinitions>
            <RowDefinition Height="0.5*"/>
            <RowDefinition Height="0.5*"/>
        </Grid.RowDefinitions>
        <StackPanel HorizontalAlignment="Stretch">
            <Button x:Name="button" Grid.Row="0" Style="{StaticResource ButtonStyle1}" Background="{Binding Background}"  HorizontalContentAlignment="Stretch">
                <Image x:Name="Image" 
            HorizontalAlignment="Right"
VerticalAlignment="Top"
Height="30"
Width="15"
Margin="5,0,0,0"
Source="close-window.png">
                    <interactivity:Interaction.Triggers>
                        <interactivity:EventTrigger EventName="Loaded">
                            <local:ScheduleBehavior TargetObject="{Binding ElementName=Schedule}"/>
                        </interactivity:EventTrigger>
                    </interactivity:Interaction.Triggers>
                </Image>
            </Button>
        </StackPanel>
        <TextBlock Margin="5" Grid.Row="1"
    VerticalAlignment="Center"
    Text="{Binding EventName}" 
    TextTrimming="CharacterEllipsis"
    TextWrapping="Wrap"
    TextAlignment="Left"
    FontWeight="Bold"/>
 
    </Grid>
</DataTemplate>
 
<syncfusion:SfScheduler x:Name="Schedule"
            ViewType="{Binding ElementName=viewTypeComboBox, Path=SelectedValue}" 
            ItemsSource="{Binding Appointments}">
 
    <syncfusion:SfScheduler.DaysViewSettings>
        <syncfusion:DaysViewSettings AppointmentTemplate="{StaticResource appointmentTemplate}"/>
    </syncfusion:SfScheduler.DaysViewSettings>
 
    <syncfusion:SfScheduler.TimelineViewSettings>
        <syncfusion:TimelineViewSettings AppointmentTemplate="{StaticResource appointmentTemplate}"/>
    </syncfusion:SfScheduler.TimelineViewSettings>
 
    <syncfusion:SfScheduler.AppointmentMapping>
        <syncfusion:AppointmentMapping StartTime="From"
                            EndTime="To"
                            Subject="EventName"
                            AppointmentBackground="Background"
                            IsAllDay="IsAllDay"/>
    </syncfusion:SfScheduler.AppointmentMapping>
</syncfusion:SfScheduler>

C#

By using the PreviousMouseDown event of the Image, you can remove appointment from the ItemsSource.

public class ScheduleBehavior : TargetedTriggerAction<Image>
{
 
    Image image;
    protected override void Invoke(object parameter)
    {
        image = this.AssociatedObject as Image;
        image.PreviewMouseDown += Button_PreviewMouseDown;
    }
 
    private void Button_PreviewMouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {
        var schedule = (this.TargetObject as SfScheduler).DataContext as SchedulerViewModel;
        var d = (e.OriginalSource as FrameworkElement).DataContext as Events;
        var itemSource = schedule.Appointments;
        if (itemSource != null && itemSource.Contains(d))
        {
            itemSource.Remove(d);
        }
    }
 
    protected override void OnDetaching()
    {
        base.OnDetaching();
        image.PreviewMouseDown -= Button_PreviewMouseDown;
        image = null;
    }
}
