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.
The AppointmentViewInfo object can be accessed via the AppointmentViewInfoCustomizingEventArgs.ViewInfo property, when handling the SchedulerControl.AppointmentViewInfoCustomizing event. This object contains information used to render an appointment or appointment part and provides properties that can be used to customize the appointment appearance (for example, AppointmentViewInfo.Subject, AppointmentViewInfo.LabelColor, AppointmentViewInfo.Interval, AppointmentViewInfo.Options, AppointmentViewInfo.CustomViewInfo, etc.).
Example
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.
