UI Automation Support for the Tab Item Control Type

This topic provides information about UI Automation support for the Tab Item 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.

A Tab Item control is used as the control within a tab control that selects a specific page to be shown in a window.

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