# Appointment Editing in WPF Scheduler (SfScheduler)
This section explains how to handle appointment editing in [WPF scheduler](https://www.syncfusion.com/scheduler-sdk/wpf-scheduler) and also explains about the appointment resizing.

## Adding appointments
Scheduler supports adding a new appointment by using the [Appointment Editor](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.SchedulerAppointmentEditorWindow.html) UI window. Open this window by double-clicking on a time cell or month cell or view header.

N>
* If [AllowViewNavigation](https://help.syncfusion.com/wpf/scheduler/date-navigations#allow-view-navigation) is true, the current view should be navigated to the respective day or timeline day views by single-clicking on the date in the view header. Other than the date by double-clicking on the view header cell, the appointment editor window will be opened, and by default, the `AllDay` checkbox will be checked in the appointment editor window.
* All-day appointments can be created by double-clicking on the view header and not applicable for the month view header.

## Editing appointment
Scheduler supports editing the appointment by using the `Appointment Editor` UI window. Open this window by double-clicking on the appointment.

![WPF Scheduler editing recurrence appointment](Appointment-Editing_Images/Editing-Recurrence-Appointment.png)

#### RecurringAppointmentBeginningEdit Event

The opening of the recurrence popup editor dialog can be handled using the `EditMode` property in the `RecurringAppointmentBeginningEditEventArgs` by handling the `RecurringAppointmentBeginningEdit` event.

`EditMode:` Gets or Sets the edit mode to perform the edit option to edit the occurrence or series for the recurrence appointment. The default value of the `EditMode` is `User.`

* User: The default editor content dialog will appear when editing a recurrence appointment to select the edit option from the end-user itself.

* Series: Edit the entire series in a recurrence appointment. The default editor content dialog will not appear.

{% highlight c# tabtitle="MainWindow.xaml.cs" hl_lines="3" %}
using Syncfusion.UI.Xaml.Scheduler;

this.scheduler.RecurringAppointmentBeginningEdit += scheduler_RecurringAppointmentBeginningEdit;

private void scheduler_RecurringAppointmentBeginningEdit(object sender, RecurringAppointmentBeginningEditEventArgs e)
{
	// Get or set the edit mode to perform the edit option.
	e.EditMode = RecurringAppointmentEditMode.Occurrence;
}
{% endhighlight %}
{% endtabs%}

#### AppointmentEditorOpening event
When the appointment editor UI window is opened to add or update an appointment, then Scheduler notifies by the [AppointmentEditorOpening](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.SfScheduler.html) event.

[AppointmentEditorOpeningEventArgs](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.AppointmentEditorOpeningEventArgs.html) has following members which provides the information for [AppointmentEditorOpening](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.SfScheduler.html) event.

It will be null when adding new appointment through appointment editor.

            e.Cancel = true;
            if (e.Appointment != null)
            {
                //Display the custom appointment editor window to edit the appointment
            }
            else
            {
                //Display the custom appointment editor window to add new appointment

    e.AppointmentEditorOptions = AppointmentEditorOptions.All | (~AppointmentEditorOptions.Background & ~AppointmentEditorOptions.Foreground & ~AppointmentEditorOptions.Reminder & ~AppointmentEditorOptions.Resource);
}
{% endhighlight %}
