AutomationElement.BoundingRectangleProperty Field


Identifies the BoundingRectangle property.

Namespace:   System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

Public Shared ReadOnly BoundingRectangleProperty As AutomationProperty

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent identifier in AutomationElementIdentifiers.

This property can also be retrieved from the Current or Cached properties.

Bounding rectangles are of type Rect. The returned rectangle is in physical screen coordinates. The default value is Empty. Empty is returned if the item is not currently displaying a user interface (UI).

The returned rectangle can contain points that are not clickable. Instances where this could happen include when the UI item has an irregular shape or clickable region, or it is obscured by other UI elements.

The following example retrieves the current value of the property. The default value is returned if the element does not provide one.

Dim boundingRect As System.Windows.Rect = CType(autoElement.GetCurrentPropertyValue(AutomationElement.BoundingRectangleProperty), System.Windows.Rect)

The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

Dim boundingRect1 As System.Windows.Rect
Dim boundingRectNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.BoundingRectangleProperty, True)
If boundingRectNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
    boundingRect1 = DirectCast(boundingRectNoDefault, System.Windows.Rect)
End If
