How to add, delete and edit the appointments in WinForms Scheduler?

Appointments in WinForms Scheduler can be managed - added, edited, or deleted - by utilizing a custom appointment form. The custom appointment form is displayed through the ShowingAppointmentForm event. The default appointment form can be suppressed by setting the e.Cancel property, and the custom form can be presented by invoking its ShowDialog method.

Code for showing custom appointment form:

AppointmentForm form;
//Hook the event for showing the appointment form.
this.scheduleControl1.ShowingAppointmentForm += scheduleControl1_ShowingAppointmentForm;

/// <summary>
/// Raise the event when showing the appointment form
/// </summary>
void scheduleControl1_ShowingAppointmentForm(object sender, ShowingAppointFormEventArgs e)
{
   //Cancel the default appointment form for schedule control.
   e.Cancel = true;
   //Shows the Custom appointment form.
   form.ShowDialog();
} 

Code for add or edit an appointment using the custom appointment form:

void OnAddorEditItem_Clicked(object sender, EventArgs e)
{
    IScheduleAppointment item;

    if (isEdit && currentAppointment != null)
    {
        //Update existing
        item = currentAppointment; 
    }
    else
    {
        //New
        item = dataProvider.NewScheduleAppointment(); 
    }

    if (item != null)
    {
        item.AllDay = true;
        item.StartTime = StartDateDateTimePickerAdv.Value;
        item.EndTime = EndDateDateTimePickerAdv.Value;
        item.Subject = SubjectTextBoxExt.Text;
        item.LabelValue = comboBox1.SelectedIndex;

        if (!isEdit)
        {
           dataProvider.AddItem(item);
        }             
    }
    schedulegrid.GetScheduleHost().SetDataToDayPanels();     
    this.Close();
} 

Code for deleting appointment:

void OnDeleteItem_Clicked(object sender, EventArgs e)
{
    //Remove the appointment
    scheduleProvider.RemoveItem(appointment);
    scheduleControl1.GetScheduleHost().SetDataToDayPanels();
}
