title: Unable to hide panels from use control in update panel
body: <p>I am loading a usercontrol in a aspx page dynamically. everything is loading under update panel. </p>
  
  <p>usercontrol contains around 100 panels. they are set to visible false by default(so that they won't be rendered to HTML) i am trying to set a panel visible on click of a button in aspx page. that is working perfectly. but when i am trying to set another panel from user control visible it is also showing previous panel. </p>
  
  <pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server"&gt;
      &lt;ContentTemplate&gt;
          &lt;asp:Panel  runat="server" ID="pnlStandard"&gt;          
              //dynamic panels from user control loaded here
          &lt;/asp:panel&gt;
          &lt;asp:LinkButton ID="LinkButton1" runat="server" 
                          class="link"&gt;test1&lt;/asp:LinkButton&gt;
          &lt;asp:LinkButton ID="LinkButton2" runat="server" 
                          class="link"&gt;test2&lt;/asp:LinkButton&gt;
      &lt;/ContentTemplate&gt;
  &lt;/asp:UpdatePanel&gt;
  </code></pre>
