UI Automation Support for the Hyperlink Control Type
This topic provides information about UI Automation support for the Hyperlink 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.
Hyperlink controls enable a user to navigate within a page, from one page to another page, and open windows.
The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Hyperlink control type. The UI Automation requirements apply to all hyperlink controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.
This topic contains the following sections.
