Find out if text is wrapped

Hi

is there a way to find if the text of Textblock with TextWrapping="Wrap"
is actually wrapped?

If I have a var "myTextBlock" in cs how can i test whether the content is currently wrapped or not?

I mean I can use FormattedText, check the width and compare it to "myTextBlock.ActualWidth", but that seems much effort. Is there sth cheaper & built-in available?

Thx!
