How to: Filter Appointments (legacy)

• Aug 03, 2020

Note

You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.

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 = Convert.ToInt32(((Appointment)e.Object).StatusKey) == 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 = Convert.ToInt32(DirectCast(e.[Object], Appointment).StatusKey) = 1
End Sub

XAML

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