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.
This event occurs in the following situations:
- the control gets focus or the focus is lost;
- the current selection is changed;
- the control switches its view;
- grouping (by dates or by resources) is changed.
