FrameworkElementAutomationPeer.IsOffscreenCore Method

Silverlight

Returns a value that indicates whether the UIElement that is associated with this FrameworkElementAutomationPeer is off the screen. This method is called by IsOffscreen.

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

protected override bool IsOffscreenCore()

Return Value

Type: System.Boolean
true if the element is not on the screen; otherwise, false.

This property does not indicate whether the element is visible. In some circumstances, an element is on the screen but is still not visible. For example, if the element is on the screen but obscured by other elements, it might not be visible. In this case the method returns false.

Notes to Inheritors

The return value for this method in the FrameworkElementAutomationPeer implementation comes from an internal property store. At run-time, this value will be populated.
