If there is one line of text you could just add necessary number of dots to the text component.
The Word Wrap property should be disabled.
Yes, I knew that "workaround". Of course that will work without Word Wrap because it's only one line that will full consumed by dots however this kind of needs it's usually only required by multi-line texts (legal stuff that uses justify text and the last line usually is filled with dots).
Unfortunately, there is now such feature in any our product.
Select your TextBox -> get Properties -> under Text Additional -> expand Text Options ->
1. set Trimming to Ellipsis Character or Ellipsis Word or Ellipsis Path
2. set LimitLine True
Thank you for the detailed information.
