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.

Example

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.
