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 Resource Navigator control allows end-users to navigate resources or change the number of visible resources (the SchedulerViewBase.ResourcesPerPage property). When the end user performs this action, the VisibleResourcesChanged event occurs.

The VisibleResourcesChanged event allows you to specify a filter for displayed resources or use the SchedulerStorage.FetchAppointments event to load appointments for visible resources only. This may be useful when a large number of resources affect the scheduler performance.
