Scrolling a dynamic text field to bottom

1

Hey.
Ive got two problems with a ‘DynamicText’

  1. how do i scroll it to the bottom?
    Im testing out a small chat thing and as soon as new text arrives i want it to scroll down to the bottom were the new text is.

  2. on this dynamic text field i have a UI component scroll bar.
    This scoll bar starts out greyed ( there is not enough text to scroll )
    but when new text is added so that the text does not fit, It does not light up and allow you to scroll using it.

thanks for help!
