title: Multiple UpdatePanelAnimationExtender Controls AjaxControlToolKit
body: <p>I am having a problem with the UpdatePanelAnimationExtender and multiple update panels.  What I want to happen is for the panel to fade out, update, and then fade back in.  </p>
  
  <p>However, it fades out all the panels and only fades the one I updated back in.  Apparently this is a rather common problem with UpdatePanelAnimationExtender, but I can't seem to find a solution.  Would anyone happen to know of a way to work around this problem?  Thanks in advance.</p>
  
  <p>Here is some sample code:</p>
  
  <pre><code>&lt;asp:UpdatePanel ID="update1" runat="server" UpdateMode="Conditional"&gt;
    //--My Code goes in here
  &lt;/asp:UpdatePanel&gt;
  
  &lt;cc1:UpdatePanelAnimationExtender ID="updateAnimation1" runat="server" TargetControlID="update1"&gt;
       &lt;Animations&gt;
           &lt;OnUpdating&gt;
                &lt;FadeOut Duration="0.2" Fps="20" /&gt;
           &lt;/OnUpdating&gt;
           &lt;OnUpdated&gt;
                &lt;FadeIn Duration="0.2" Fps="20" /&gt;
           &lt;/OnUpdated&gt;
       &lt;/Animations&gt;
  &lt;/cc1:UpdatePanelAnimationExtender&gt;
  
  &lt;asp:UpdatePanel ID="update2" runat="server" UpdateMode="Conditional"&gt;
    //--My Code goes in here
  &lt;/asp:UpdatePanel&gt;
  
  &lt;cc1:UpdatePanelAnimationExtender ID="updateAnimation2" runat="server" TargetControlID="update2"&gt;
       &lt;Animations&gt;
           &lt;OnUpdating&gt;
                &lt;FadeOut Duration="0.2" Fps="20" /&gt;
           &lt;/OnUpdating&gt;
           &lt;OnUpdated&gt;
                &lt;FadeIn Duration="0.2" Fps="20" /&gt;
           &lt;/OnUpdated&gt;
       &lt;/Animations&gt;
  &lt;/cc1:UpdatePanelAnimationExtender&gt;
