How do I get a vertical scroll bar to scroll down with the text entered into Rich Text Box Control?  I have given the rich text box the following properties:

this.displayTextBox.ScrollBars = System.Windows.Forms.ScrollBars.Vertical;
this.displayTextBox.Multiline = true;

But the scroll bar stays at the top of the rich text box when the text is greater than the length of the text box!!  Can anyone provide any code so that the scroll bar stays at the bottom of the rich text box?

I made small test and found that when user types text to multi-line RichTextBox, it is scrolled down automatically.
However, when text is set from the program, this doesn't happen. To do this you can use ScrollToCaret function:

richTextBox1.Text = "1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n2";       // test
richTextBox1.Select(richTextBox1.Text.Length, 0);
richTextBox1.ScrollToCaret();

RichTextBox1.SelectionStart = RichTextBox1.Text.Length;
