How do I automatically scroll to the bottom of a multiline text box?

Question

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?

Answer 1

You can use the following code snippet:

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

which will automatically scroll to the end.

Answer 2

Try to add the suggested code to the TextChanged event:

private void textBox1_TextChanged(object sender, EventArgs e) { textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret(); }
