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.

• Required UI Automation Tree Structure
• Required UI Automation Properties
• Required UI Automation Control Patterns
• Required UI Automation Events

Required UI Automation Tree Structure

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

Control View	Content View
Hyperlink	Hyperlink

Required UI Automation Properties

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

UI Automation Property	Value	Notes
AutomationIdProperty	See notes.	The value of this property needs to be unique across all controls in an application.
BoundingRectangleProperty	See notes.	The outermost rectangle that contains the whole control.
ClickablePointProperty	See notes.	Supported if there is a bounding rectangle. If not every point within the bounding rectangle is clickable, and you perform specialized hit testing, then override and provide a clickable point.
IsKeyboardFocusableProperty	See notes.	If the control can receive keyboard focus, it must support this property.
NameProperty	See notes.	The hyperlink control’s name is the text that is displayed on the screen as underlined.
ClickablePointProperty	See notes.	The hyperlink control’s clickable point must be a point that launches the hyperlink if clicked with a mouse pointer.
LabeledByProperty	Null	If there is a static text label then this property must expose a reference to that control.
ControlTypeProperty	Hyperlink	This value is the same for all UI frameworks.
LocalizedControlTypeProperty	"hyperlink"	Localized string corresponding to the Hyperlink control type.
IsContentElementProperty	True	The hyperlink control is always included in the content view of the UI Automation tree.
IsControlElementProperty	True	The hyperlink control is always included in the control view of the UI Automation tree.

Required UI Automation Control Patterns

The following table lists the UI Automation control patterns required to be supported by all hyperlink controls. For more information on control patterns, see UI Automation Control Patterns Overview.

Control Pattern/Pattern Property	Support/Value	Notes
IInvokeProvider	Yes	All hyperlink controls must support the Invoke pattern.

Required UI Automation Events

The following table lists the UI Automation events required to be supported by all hyperlink controls. For more information on events, see UI Automation Events Overview.

UI Automation Event	Support	Notes
InvokedEvent	Required	None
BoundingRectangleProperty property-changed event.	Required	None
IsOffscreenProperty property-changed event.	Required	None
IsEnabledProperty property-changed event.	Required	None
AutomationFocusChangedEvent	Required	None
StructureChangedEvent	Required	None
