Can't scroll to end of document

Hi, I am using SyntaxEditor as a logging kind of control where new text is constantly added to the end. In relation to this I also want the SyntaxEditor control to always scroll to the bottom. I have tried a lot of different ways, how can I do this? This is my current code
