#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.
If you need to implement conditional styling based on the appointment data, handle the AppointmentViewInfoCustomizing event, and modify any appearance property using the appointment’s data as a condition.
#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.
