Hi Esha You have to write code like this: textBox1.Text += Test string 
; textBox1.Update(); textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret(); OR you can use the following code: textBox1.AppendText(This is a test string 
); textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret();
