how i symbol inside an asp:updatepanel transform whole page?

i have symbol inside an transform quarrel i transform whole page. i have set childrenastriggers="false" updatemode="conditional".

i have illustration formula here demonstrates problem.

<asp:updatepanel id="myfirstpanel" runat="server" childrenastriggers="false" updatemode="conditional">
   <contenttemplate>
      <asp:button runat="server" id="myfirstbutton" text="my initial button" onclick="myfirstbutton_click" />
      <asp:button runat="server" id="mysecondbutton" text="my second button" onclick="mysecondbutton_click" />
   </contenttemplate>
</asp:updatepanel>

<asp:updatepanel id="mysecondpanel" runat="server">
   <contenttemplate>
       <asp:label runat="server" id="myfirstlabel" text="my initial label"></asp:label>
    </contenttemplate>
    <triggers>
       <asp:asyncpostbacktrigger controlid="myfirstbutton" eventname="click" />
    </triggers>
</asp:updatepanel>
<asp:label runat="server" id="mysecondlabel" text="my second label"></asp:label>

and formula behind:

protected vacant myfirstbutton_click(object sender, eventargs e)
{
  myfirstlabel.text = "inside quarrel " + datetime.now.tostring("mm:ss");
}
protected vacant mysecondbutton_click(object sender, eventargs e)
{
  mysecondlabel.text = "outside quarrel " + datetime.now.tostring("mm:ss");
}

i wish transform tag inside an transform quarrel second symbol clicked.
the second symbol needs an transform panel. i don't wish put lable an transform panel.
