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.
By default, the All and None items are shown in the combo box.
If you want to hide the None item, set the ShowNoneResourcesItem property to false. To decide whether the All item should be shown, use the ResourcesComboBoxControl.ShowAllResourcesItem property.
