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 provides information about UI Automation support for the TitleBar control type. In UI Automation, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. The conditions include specific guidelines for UI Automation tree structure, UI Automation property values and control patterns.

Title bar controls represent titles or caption bars in a window.

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

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