SchedulerControl.OptionsCustomization Property

Provides access to the Scheduler control’s customization options.

Namespace: DevExpress.Xpf.Scheduler

Assembly: DevExpress.Xpf.Scheduler.v21.2.dll

NuGet Package: DevExpress.Wpf.Scheduler

Declaration

C#

public OptionsCustomization OptionsCustomization { get; set; }

VB.NET

Public Property OptionsCustomization As OptionsCustomization

Property Value

Type	Description
OptionsCustomization	An OptionsCustomization object which provides a set of properties specifying the functionality currently available to end-users.

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.

Use the OptionsCustomization property to implement end-user restrictions, if it is necessary to prevent end-users from creating (the OptionsCustomization.AllowAppointmentCreate property), deleting (the OptionsCustomization.AllowAppointmentDelete property) or editing (the OptionsCustomization.AllowAppointmentEdit property) appointments shown within the SchedulerControl. To get the complete list of the available options and their descriptions, refer to the OptionsCustomization.

Example

This example demonstrates how to prevent end-users from having appointments within a certain time interval (from 2 PM to 3 PM). To implement end-user restrictions, handle the SchedulerControl.AllowAppointmentCreate event to prevent end-users from creating appointments within a certain time interval and the SchedulerControl.AllowAppointmentConflicts event to prevent an existing appointment from being dragged to the same time interval:
