User control communication
<p>I have a master page that contains a user control <code>ucStatusBar</code>. <code>ucStatusBar</code> has a public method <code>setStatus()</code>. The method simply updates an <code>&lt;asp:label /&gt;</code> in the control with the string param passed in. </p>

<p>The master page content page is <em>Summary.aspx</em>.  <em>Summary.aspx</em> has a user control <code>ucNewEvent</code>.  When the form <code>ucNewEvent</code> is saved and either a success or fail code is returned, I am trying to update <code>ucStatusBar</code> with the success or fail message. I can call <code>ucStatusBar.setStatus("success message")</code> but i get a <code>null</code> reference exception at runtime when <code>setStatus</code> tries to set the <code>Text</code> property of the label b/c for some reason the <code>&lt;asp:label /&gt;</code> is <code>null</code>.  Why would this be <code>null</code>?  Is there a better way to achieve this?</p>
