Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns a value that indicates whether the item element that is associated with this ItemAutomationPeer is off the screen. This method is called by IsOffscreen.

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

Syntax

'Declaration
Protected Overrides Function IsOffscreenCore As Boolean
protected override bool IsOffscreenCore()

Return Value

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

Remarks

If the item is a UIElement with its own peer as reported by Owner, then information from that peer is forwarded. Next, the container peer (which could be ItemsControlAutomationPeer, ListBoxAutomationPeer, or another class) is used as a possible source. Finally, if there is no container peer, then this method returns true.
