I'll be using only one eventhandler in transferring focus to other controls.

Why? Have you tried separate handlers for each control?

txtBoxLogIn.Tag = txtBoxPassword; // give focus to the password box
txtBoxPassword.Tag = btnProceedLogIn; // give focus to the button
btnProceedLogIn.Tag = null; // set this to null to signify the end of the chain

private void focusForwardingControl_KeyDown(object sender, KeyEventArgs e)

    Control control = sender as Control;
    if (control == null)
