UI Automation Support for the Menu Control Type

This topic provides information about Microsoft UI Automation support for the Menu control type. It describes the control's Microsoft UI Automation tree structure and provides the properties and control patterns for specific control scenarios.

A menu control allows hierarchal organization of elements associated with commands and event handlers. In a typical Microsoft Windows application, a menu bar contains several menu buttons (such as File, Edit, and Window), and each menu button displays a menu. A menu contains a collection of menu items (such as New, Open, and Close), which can be expanded to display additional menu items or to perform a specific action when clicked.

The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Menu control type. The UI Automation requirements apply to all list controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.

This topic contains the following sections.

The following table depicts the control view and the content view of the UI Automation tree that pertains to menu controls and describes what can be contained in each view. For more information on the UI Automation tree, see UI Automation Tree Overview.

Control View

Content View

  • Menu

    • MenuItem (1 or many)

  • Menu

    • MenuItem (1 or many)

Menu controls always appear in the control view and the content view of the UI Automation tree. Menu control types should appear under the control that their information is referring to. UI Automation clients must listen for MenuOpenedEvent to ensure that they consistently obtain information conveyed by menu controls. Context menu controls are a special case. They appear as children of the Desktop.

The following table lists the UI Automation properties whose value or definition is especially relevant to the Menu control type. For more information on UI Automation properties, see UI Automation Properties for Clients.
