UI Automation Support for Standard Controls

Note Note

This documentation is intended for .NET Framework developers who want to use the managed UI Automation classes defined in the System.Windows.Automation namespace. For the latest information about UI Automation, see Windows Automation API: UI Automation.

This topic contains information about Microsoft UI Automation support for standard controls in applications developed for the WPF, Win32, and Windows Forms frameworks.

This topic contains the following sections.

All WPF control elements that provide information or support for user interaction have full native support for UI Automation. Other elements, such as panels, are not visible to UI Automation.

Most Win32 controls are exposed to Microsoft UI Automation through client-side providers in UIAutomationClientsideProviders.dll. This assembly is automatically registered for use with UI Automation client applications.

Full support is provided only for controls from version 6 of ComCtrl32.dll (available with Microsoft Windows XP and later).

The following controls are supported.
