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.

Use the Customizations property to manage popup menu items (for example, remove existing menu items or/and add new items). SchedulerControl also provides the SchedulerControl.DefaultMenuCustomizations and SchedulerControl.AppointmentMenuCustomizations properties, allowing you to customize default and appointment popup menus.

Example

This example demonstrates how to customize the SchedulerControl’s context menu at runtime by removing the New Recurring Appointment menu item from the Default Popup Menu, and adding a custom item instead.

Handle the SchedulerControl.PopupMenuShowing event. In the event handler, use the SchedulerMenuEventArgs.Menu property to determine whether the default popup menu raised an event, and modify the SchedulerMenuEventArgs.Customizations collection to add or remove popup menu items.

                        HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                        PopupMenuShowing="schedulerControl1_PopupMenuShowing">

MainWindow.xaml.cs

private void schedulerControl1_PopupMenuShowing(object sender, SchedulerMenuEventArgs e) {
    // Check whether this event was raised for a default popup menu of the Scheduler control.
    if (e.Menu.Name == SchedulerMenuItemName.DefaultMenu)
    {
        for (int i = 0; i < e.Menu.Items.Count; i++)
        {
            SchedulerBarItem menuItem = e.Menu.Items[i] as SchedulerBarItem;
            if (menuItem != null)
            {
                if (menuItem != null && menuItem.Name == SchedulerMenuItemName.NewAllDayEvent)
                {
                    menuItem.Content = "Create All-Day Appointment";
                    break;
                }
            }
        }

        // Remove the New Recurring Event menu item using the Action approach.
        e.Customizations.Add(new RemoveBarItemAndLinkAction()
        {
            ItemName = SchedulerMenuItemName.NewRecurringEvent

        e.Customizations.Add(new BarItemLinkSeparator());
        // Insert a new item into the Scheduler popup menu.
