Hyperlink Control Type

This topic provides information about Microsoft UI Automation support for the Hyperlink control type.

Hyperlink controls create links that enable users to navigate within the same page, or from one page to another.

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 where the UI framework/platform integrates UI Automation support for control types and control patterns.

This topic contains the following sections.

Typical Tree Structure

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

Control ViewContent View

Relevant Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to the hyperlink controls. For more information about UI Automation properties, see Retrieving Properties from UI Automation Elements.

UI Automation PropertyValueNotes
UIA_AutomationIdPropertyIdSee notes.The value of this property must be unique across all controls in an application.
UIA_BoundingRectanglePropertyIdSee notes.The outermost rectangle that contains the whole control.
UIA_ClickablePointPropertyIdSee notes.The hyperlink control's clickable point must be a point that launches the hyperlink if clicked with a mouse pointer.
UIA_ControlTypePropertyIdHyperlink
UIA_IsContentElementPropertyIdTRUEThe hyperlink control is always included in the content view of the UI Automation tree.
UIA_IsControlElementPropertyIdTRUEThe hyperlink control is always included in the control view of the UI Automation tree.
UIA_IsKeyboardFocusablePropertyIdSee notes.If the control can receive keyboard focus, it must support this property.
UIA_LabeledByPropertyIdSee notes.If there is a static text label, this property must expose a reference to that control.
UIA_LocalizedControlTypePropertyIdSee notes.Localized string corresponding to the Hyperlink control type. The default value is "hyperlink" for en-US or English (United States).
UIA_NamePropertyIdSee notes.The hyperlink control's name is the text that is displayed on the screen as underlined.

 

Required Control Patterns

The following table lists the UI Automation control patterns that hyperlink controls are required to support. For more information on control patterns, see UI Automation Control Patterns Overview.

Control Pattern/Pattern PropertySupport/ValueNotes
IInvokeProvider RequiredAll hyperlink controls must support the Invoke control pattern.
IValueProvider DependsHyperlink controls should support the Value control pattern when the link contains information that is usable and meaningful to the user.
Value For example, "http://www..."A URL for an Internet or intranet address is an example of a hyperlink that contains information that is meaningful to the user. A programmatic link, however, is meaningful only to an application and is not recommended for the Value property.

 

Required Events

The following table lists the UI Automation events that hyperlink controls are required to support. For more information on events, see UI Automation Events Overview.

UI Automation EventNotes
UIA_AutomationFocusChangedEventId
UIA_BoundingRectanglePropertyId property-changed event.
UIA_Invoke_InvokedEventId
UIA_IsEnabledPropertyId property-changed event.If the control supports the IsEnabled property, it must support this event.
UIA_IsOffscreenPropertyId property-changed event.If the control supports the IsOffscreen property, it must support this event.
UIA_StructureChangedEventId

 

Remarks

The Hyperlink control type should be applied only to an object that, when clicked, causes navigation to occur; it should not be applied to the container of the hyperlink. For example, only the clickable "hot spots" inside an image map should have the Hyperlink control type. The same is true of hyperlinks in a text field or document container. In this case, only the hyperlink text or image should have the Hyperlink control type, not the container.

The Text control pattern is ideal for supporting embedded hyperlinks in text or document elements.
