NuGet Packages: DevExpress.WindowsDesktop.Wpf.Spreadsheet, DevExpress.Wpf.Spreadsheet

Declaration

C#

public BarManagerActionCollection Customizations { get; }

VB.NET

Public ReadOnly Property Customizations As BarManagerActionCollection

Property Value

Type	Description
BarManagerActionCollection	A BarManagerActionCollection object.

Remarks

The Customizations property enables you to add or remove menu items.

This example demonstrates how to customize the SpreadsheetControl’s context menu - remove the existing menu items and add new items.

Handle the SpreadsheetControl.PopupMenuShowing event. Use the PopupMenuShowingEventArgs.MenuType property to determine the visual element for which the popup menu is invoked.

To remove a menu item, create the RemoveSpreadsheetCommandAction object, set its ID to the ID of the command to remove and add that object to the PopupMenuShowingEventArgs.Customizations collection.

To add a new menu item, create a new BarButtonItem and add it to the PopupMenuShowingEventArgs.Customizations collection.
