SchedulerControl.PopupMenuShowing Event

Occurs before a popup menu is created for a Scheduler every time a context menu is invoked.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v19.1.dll


public event PopupMenuShowingEventHandler PopupMenuShowing

Event Data

The PopupMenuShowing event's data class is PopupMenuShowingEventArgs. The following properties provide information specific to this event:

Property Description
Menu Gets or sets the popup (context) menu for which this event was raised.


Handle the PopupMenuShowing event to change specific items in the popup menu every time it is shown. Note that the current popup menu can be accessed via the PopupMenuShowingEventArgs.Menu property.

The types of all popup menu items are listed in the SchedulerMenuItemId enumeration.

To retrieve the right-clicked appointment (or the appointment group), access the SchedulerControl.SelectedAppointments collection.

This example demonstrates how to customize the SchedulerControl‘s popup menus (the SchedulerMenuItemId.DefaultMenu in this case). To add, remove or modify items in a popup menu, handle the SchedulerControl.PopupMenuShowing event of a Scheduler Control, and then use the PopupMenuShowingEventArgs.Menu property.

using DevExpress.Utils.Menu;
using DevExpress.XtraScheduler;
using DevExpress.XtraScheduler.Services;
using DevExpress.XtraScheduler.Commands;
// ...
private void schedulerControl1_PopupMenuShowing(object sender, PopupMenuShowingEventArgs e)
    if (e.Menu.Id == DevExpress.XtraScheduler.SchedulerMenuItemId.DefaultMenu)
        // Hide the "Change View To" menu item.
        SchedulerPopupMenu itemChangeViewTo = e.Menu.GetPopupMenuById(SchedulerMenuItemId.SwitchViewMenu);
        itemChangeViewTo.Visible = false;

        // Remove unnecessary items.

        // Disable the "New Recurring Appointment" menu item.

        // Find the "New Appointment" menu item and rename it.
        SchedulerMenuItem item = e.Menu.GetMenuItemById(SchedulerMenuItemId.NewAppointment);
                if (item != null) {
                    item.Caption = "&New Meeting";
                    item.ImageOptions.SvgImage = DevExpress.Utils.Svg.SvgImage.FromFile("NewItem.svg");

        // Create a menu item for the Scheduler command.
        ISchedulerCommandFactoryService service = schedulerControl1.GetService<ISchedulerCommandFactoryService>();
        SchedulerCommand cmd = service.CreateCommand(SchedulerCommandId.SwitchToGroupByResource);
        SchedulerMenuItemCommandWinAdapter menuItemCommandAdapter =
            new SchedulerMenuItemCommandWinAdapter(cmd);
        DXMenuItem menuItem = (DXMenuItem)menuItemCommandAdapter.CreateMenuItem(DXMenuItemPriority.Normal);
        menuItem.BeginGroup = true;

        // Insert a new item into the Scheduler popup menu and handle its click event.
        e.Menu.Items.Add(new SchedulerMenuItem("Click me!", MyClickHandler));

public void MyClickHandler(object sender, EventArgs e)
    MessageBox.Show("My Menu Item Clicked!");
