I want to modify the code in such a way that once the text scrolls down to its length then it should start from 1 again. Is it possible ? If yes then how

Hi,

you have to use like this

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

Hi Esha,

You have to write code like this:
textBox1.Text += "Test string \n";
textBox1.Update();
textBox1.SelectionStart = textBox1.Text.Length;
textBox1.ScrollToCaret();

OR, you can use the following code:
textBox1.AppendText("This is a test string \n");
textBox1.SelectionStart = textBox1.Text.Length;
textBox1.ScrollToCaret();
