You can’t make it quite automatic, but if you can catch the event when barcode data is available, you set the control to have focus in your code using the ActiveControl property of the Form class:

class BarcodeForm : Form {

  ...

  void barCode1_DataAvailable(object sender, EventArgs e) {

    // Check that active control is a TextBox

    TextBox textBox = this.ActiveControl as TextBox;

    if( textBox == null ) return;

    // Get data from the barcode reader

    textBox.Text = GetBarcodeData();

    // Set the next active control

    if( textBox == textBox1 ) this.ActiveControl = textBox2;

  }

}
