UI Automation Support for the Separator Control Type

This topic provides information about UI Automation support for the Separator 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.

Separator controls are used to visually divide a space into two regions. For example, a separator control can be a bar that defines two panes in a window.

The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Separator control type. The UI Automation requirements apply to all list 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 separator controls and describes what can be contained in each view. For more information on the UI Automation tree, see UI Automation Tree Overview.

Control View	Content View
Separator	The Separator control never has content.

Required UI Automation Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to separator controls. 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	""	The separator control does not require a NameProperty.
LabeledByProperty	null	The separator control does not have a static label.
ControlTypeProperty	Separator	This value is the same for all UI frameworks.
LocalizedControlTypeProperty	"Separator"	Localized string corresponding to the Separator control type.
IsContentElementProperty	False	The separator control is never content.
IsControlElementProperty	True	The separator control must always be a control.
