FormShowingEventArgs Class

Provides data for the events which show dialogs invoked by the Scheduler control.

Namespace: DevExpress.Xpf.Scheduler

Assembly: DevExpress.Xpf.Scheduler.v24.2.dll

NuGet Package: DevExpress.Wpf.Scheduler

#Declaration

public abstract class FormShowingEventArgs :
    EventArgs

#Remarks

Important

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.

Events, which use objects of classes derived from the FormShowingEventArgs base class, occur before different Scheduler control dialogs are invoked. The FormShowingEventArgs class introduces the FormShowingEventArgs.Form property, that allows replacing the default form with a custom form, and the FormShowingEventArgs.Cancel property, specifying the value indicating whether to cancel invoking the form.
