There is an event handler MouseLeftMouseButton. When the event handler was triggered, use textbox.Focus() inside the handler.

If i'm right, your intention is to get the keyboard commands and display the char pressed into your textbox even if the focus is on other controls.

If that is the case, you can route the keyboard commands to the root control (control in the top level... eg: window), analyse them and display in the textbox. I'ld try to give examples if that helps.

EDIT:

private void Window_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
  if (Keyboard.Modifiers != ModifierKeys.Shift)
  {
    if (e.Key > Key.A && e.Key < Key.Z)
    {
      textBox1.Text += e.Key.ToString().ToLower();
    }
  }
  else
  {
    if (e.Key > Key.A && e.Key < Key.Z)
    {
      textBox1.Text += e.Key.ToString();
    }
  }            
  e.Handled = true;
}

Add to the TextBox.OnLostFocus event a handler which sets the focus to the TextBox.
