Automatic line-break in dynamic text-box?

Hi people, and good morning

Have a problem with some externally loaded text. Its loads the text in fine, but theres actually a good amount of text, and its gonna be updated frequently, so i want to keep it a automatic as possible. So the big question is:

Can i make my dynamic text-box automatically adjust its height, to the amount of text loaded? Some simple way, or some function that ive overlooked?

Thanks in advance
