The EditField style has a different colour for focus/unfocused. It was actually me that added it so that I could do exactly what I think you are trying to do (highlight the currently focused EditField).

This has the advantage that you can set it for every EditField in your app with one line:

EditField::StyleDefault().Write().focus = Yellow();

But if you really want to only change the colour when a field has text in it then this works:

void CtrlLibTest::OnEdit(EditField *ctrl)
{
	static EditField::Style s = EditField::StyleDefault();
	s.focus = Yellow();
	ctrl->SetStyle(ctrl->GetLength() ? s : EditField::StyleDefault());
}

Incidentally, you can avoid the need for a dynamic cast by setting the callback to this function with the ctrl as a parameter:

edit1 <<= THISBACK1(OnEdit, &edit1);
edit2 <<= THISBACK1(OnEdit, &edit2);
...etc

Hope that helps!
