NuGet Package: DevExpress.Wpf.Scheduler


public UserControl Form { get; set; }

Property Value

Type Description

A UserControl class descendant that represents the form that will be displayed.



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.

Use the Form property to specify the form to be invoked after the corresponding event is handled. For example, you can use this property to replace the default form with a custom form.


This example demonstrates how to replace the standard Edit Appointment form with a custom one, and prevent end-users from resizing this form via the SchedulerControl.EditAppointmentFormShowing event.

using DevExpress.Xpf.Scheduler;
// ...

private void schedulerControl1_EditAppointmentFormShowing(object sender, EditAppointmentFormEventArgs e) {
    e.Form = new CustomAppointmentForm(this.schedulerControl1, e.Appointment);
    e.AllowResize = false;
