You can use OnDrawStyleText event of TRVStyle.

var uWord: string;//text to be underlined.

procedure TForm1.RVStyle1DrawStyleText(Sender: TRVStyle; const s: String;

  Canvas: TCanvas; StyleNo, SpaceBefore, Left, Top, Width, Height: Integer;

  DrawState: TRVTextDrawStates; var DoDefault: Boolean);

var p: integer;

    s2: string;

begin

  p:=Pos(uWord, s);

  s2:=s;

  while p>=1 do

  begin

    s2[p]:=' ';

    Canvas.Pen.width:=1;

    Canvas.Pen.Color:=clRed;

    Canvas.MoveTo(left+Canvas.TextWidth(Copy(s, 0, p-1)), top+height);

    Canvas.LineTo(left+Canvas.TextWidth(Copy(s, 0, p-1)+uWord), top+height);

    p:=Pos(uWord, s2);

  end;

end;
