I have a textbox with the .Multiline property set to true. At regular intervals, I am adding new lines of text to it. I would like the textbox to automatically scroll to the bottom-most entry (the newest one) whenever a new line is added. How do I accomplish this?

You can use the following code snippet:

myTextBox.SelectionStart = myTextBox.Text.Length;
myTextBox.ScrollToCaret();

which will automatically scroll to the end.

I use this. Simple, clean and fast!

txtTCPTxRx.AppendText(newText);

Below is the actual code I use

ThreadSafe(() =>
      {
          string newLog = $"{DateTime.Now:HH:mm:ss:ffff->}{dLog}{Environment.NewLine}";
          txtTCPTxRx.AppendText(newLog);
      });

With regards to the comment by Pete about a TextBox on a tab, the way I got that to work was adding

textBox1.SelectionStart = textBox1.Text.Length;
textBox1.ScrollToCaret();

to the tab's Layout event.
