Problem with Auto Wrap Text property

Hello. I have a text that I want to dynamically wrap. I set the property Auto Wrap Text to true and I set a value to Wrap Text At, but nothing happens. How am I able to achieve this? I have also tried to put this text into Border, Wrap Box, Size Box, Scale Box, Scroll Box, Vertical Box and Horizontal Box, but again nothing happens.Before I post this, I saw these links link1, link2. However, I couldn’t get it right. Am I doing something wrong?
Thank you in advance.
