Examples

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

bool isControlOffscreen = (bool)
   autoElement.GetCurrentPropertyValue(AutomationElement.IsOffscreenProperty);

Dim isControlOffscreen As Boolean = _
    CBool(autoElement.GetCurrentPropertyValue(AutomationElement.IsOffscreenProperty))

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.

bool isControlOffscreen1;
object isOffscreenNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.IsOffscreenProperty, true);
if (isOffscreenNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    isControlOffscreen1 = (bool)isOffscreenNoDefault;
}

Dim isControlOffscreen1 As Boolean
Dim isOffscreenNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.IsOffscreenProperty, True)
If isOffscreenNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    isControlOffscreen1 = CBool(isOffscreenNoDefault)
End If
