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.
