How to: Filter Appointments

• May 22, 2020

This example demonstrates how to use the SchedulerStorage.FilterAppointment event to filter appointments shown within a Scheduler Control according to specific conditions. Specifically, the code below hides all tentative appointments (those whose status is set to AppointmentStatusType.Tentative).

C#

using DevExpress.XtraScheduler;
// ...

private void SchedulerStorage_FilterAppointment(object sender, PersistentObjectCancelEventArgs e) {
    // Filter all tentative appointments.
    e.Cancel = ((Appointment)e.Object).StatusId == 1;
}

VB.NET

Imports Microsoft.VisualBasic
Imports DevExpress.XtraScheduler
' ...

Private Sub SchedulerStorage_FilterAppointment(sender As System.Object, _
                                               e As PersistentObjectCancelEventArgs)
    ' Filter all tentative appointments.
    e.Cancel = CType(e.Object, Appointment).StatusId = 1
End Sub

XAML

<dxsch:SchedulerControl.Storage>
    <dxsch:SchedulerStorage FilterAppointment="SchedulerStorage_FilterAppointment"/>
</dxsch:SchedulerControl.Storage>
