You need to get the KeyEventArgs to detect what key has been pressed. But assuming that when a user presses Tab or Shift+Tab the control loses focus you can just listen on the OnKeyDown or OnKeyPress and check if the pressed items are Tab or Shift+Tab

    private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
    { 
        //Check for Tab key
        if (e.KeyCode == Keys.Tab)
        {
           //Do something
        }
        //Check for the Shift Key as well
        if (Control.ModifierKeys == Keys.Shift && e.KeyCode == Keys.Tab) {
            //Other stuff to do
        }
    }
