# Events in WPF Scheduler (SfScheduler)

## CellTapped

The [CellTapped](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.SfScheduler.html) event occurs when the user clicks or touches a cell in Scheduler.
This event receives two arguments namely `this` that handles `SfScheduler` and [CellTappedEventArgs](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html) as objects.

The [CellTappedEventArgs](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html) object contains the following properties:

* [Appointment](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_Appointment) - returns the tapped appointment values.

    1. If [ItemsSource](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.SfScheduler.html#Syncfusion_UI_Xaml_Scheduler_SfScheduler_ItemsSourceProperty) added with custom business object then tapped custom Appointment details can get by using Appointment [Data](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.ScheduleAppointment.html#Syncfusion_UI_Xaml_Scheduler_ScheduleAppointment_Data) property in Cell tapped arguments. 

    2. The tapped appointment is a Recurrence appointment it will return the parent recurrence appointment values. 

    3. The appointment details get for month view if [AppointmentDisplaymode](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.MonthViewSettings.html#Syncfusion_UI_Xaml_Scheduler_MonthViewSettings_AppointmentDisplayMode) as [Appointment](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_Appointment), or else it will be null for month view.
* [Appointments](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_Appointments)- returns Tapped Month cell appointments values if AppointmentDisplayMode as indicator. Tapped Month Cell has a Recurrence appointment it will return the parent recurrence appointment values. It will be null for Day or Week or WorkWeek views.
* [IsMoreAppointments](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_IsMoreAppointments)- specifies whether more appointments are tapped in month view. It will be applicable only for Month view which has AppointmentDisplaymode as Appointment.
* [CancelNavigation](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_CancelNavigation)- specifies whether day view navigation should be disabled when clicking more appointments in month view. It will be applicable for month view which has AppointmentDisplaymode as Appointment and click the More appointments in month cell.
* [DateTime](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_DateTime)- gets the date-time of the tapped cell.
* [TimeInterval](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_TimeInterval)- gets the date-time interval of the tapped cell. It is not applicable for month view.
* [Resource](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Scheduler.CellTappedEventArgs.html#Syncfusion_UI_Xaml_Scheduler_CellTappedEventArgs_Resource) - gets the resource associated with the timeslot cell where user tapped.
