AppointmentViewInfo.CustomViewInfo Property

Gets or sets a custom object to be used for rendering the appointment.

Namespace: DevExpress.Xpf.Scheduler.Drawing

Assembly: DevExpress.Xpf.Scheduler.v20.1.dll

Declaration

public object CustomViewInfo { get; set; }
Public Property CustomViewInfo As Object

Property Value

Type Description
Object

An object used for customizing the appointment's visual representation.

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 CustomViewInfo property to specify a custom object (for example, resource image) to be displayed within an appointment.

Examples

TIP

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E2999.

This example demonstrates how to use the AppointmentViewInfo.Subject, AppointmentViewInfo.Location, AppointmentViewInfo.Description, AppointmentViewInfo.CustomViewInfo, SchedulerViewBase.AppointmentToolTipContentTemplate properties and SchedulerControl.AppointmentViewInfoCustomizing event to define and apply a custom template for showing an appointment subject, location, description and resource images within appointment tooltips.
