  <pre><code>    &lt;asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" RenderMode="Inline"&gt;
  &lt;ContentTemplate&gt;
      &lt;div class="VidVote"&gt;
      &lt;ul class='star-rating'&gt;
          &lt;asp:Panel ID="CurrRate" runat="server"&gt;&lt;/asp:Panel&gt;
          &lt;li&gt;&lt;asp:Button ID="OneCati" CssClass="one-star" runat="server" 
              onclick="OneCati_Click" CausesValidation="False" /&gt;&lt;/li&gt;
          &lt;li&gt;&lt;asp:Button ID="TwoCati" CssClass="two-stars" runat="server" 
              onclick="TwoCati_Click" CausesValidation="False" /&gt;&lt;/li&gt;
          &lt;li&gt;&lt;asp:Button ID="ThreeCati" CssClass="three-stars" runat="server" 
              onclick="ThreeCati_Click" CausesValidation="False" /&gt;&lt;/li&gt;
          &lt;li&gt;&lt;asp:Button ID="FourCati" CssClass="four-stars" runat="server" 
              onclick="FourCati_Click" CausesValidation="False" /&gt;&lt;/li&gt;
          &lt;li&gt;&lt;asp:Button ID="FiveCati" CssClass="five-stars" runat="server" 
              onclick="FiveCati_Click" CausesValidation="False" /&gt;&lt;/li&gt;
      &lt;/ul&gt;
      &lt;/div&gt;
  &lt;/ContentTemplate&gt;
      &lt;Triggers&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="OneCati" EventName="Click" /&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="TwoCati" EventName="Click" /&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="ThreeCati" EventName="Click" /&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="FourCati" EventName="Click" /&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="FiveCati" EventName="Click" /&gt;
      &lt;/Triggers&gt;
  &lt;/asp:UpdatePanel&gt;
  &lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" RenderMode="Inline"&gt;
  &lt;ContentTemplate&gt;
      &lt;div class="VidScore"&gt;
      &lt;h3 style='text-align:center;margin-bottom:0; font-size:40px;'&gt;
          &lt;asp:Label ID="Score" runat="server" Text="Label"&gt;&lt;/asp:Label&gt;
      &lt;/h3&gt;
