怎么让它在新的页面跳出？

<asp:MenuItem Text="R5E2" Value="R5E2">
                                <asp:MenuItem Text="iLO" Value="iLO">
                                    <asp:MenuItem Text="OA1 172.16.254.120" Value="OA1 172.16.254.120"
                                        NavigateUrl="http://172.16.254.120">
                                    </asp:MenuItem>
