Find dynamic control inside DevExpress Dockpanel
<p>I have a added a dynamic dev express dockPanel to my asxp page. Inside that dynamic dockPanel I dynamically create a dynamic gauge control. I want to perform a callback on the gauge to update its value. </p>

<p>Currently the callback should be executed inside this ASPxTimer:</p>

<pre><code>&lt;dx:ASPxTimer ID="ASPxTimer1" runat="server" Interval="5000"&gt;
        &lt;ClientSideEvents Tick="function(s, e) {gaugeControl1.PerformCallback();}" /&gt;
&lt;/dx:AspxTimer&gt;
</code></pre>

<p>The problem is when I load the site, I get an error: Microsoft JScript runtime error: Unable to get value of the property 'parentNode': object is null or undefined</p>

<p>It appears that the callback is trying to be performed on the dockPanel instead of the gauge. Any idea on how I can fix this?</p>
