title: How to change programatically a span text inside a ProgressTemplate in C#?
body: <p>I have the following UpdateProgress:</p>
  
  <pre><code>&lt;asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="updCampos"
      DynamicLayout="true"&gt;
      &lt;ProgressTemplate&gt;
          &lt;div class="carregando"&gt;
              &lt;span id="sAguarde"&gt;Aguarde ...&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;asp:Image ID="Image1" runat="server" ImageUrl="~/images/loading.gif" /&gt;
          &lt;/div&gt;
      &lt;/ProgressTemplate&gt;
  &lt;/asp:UpdateProgress&gt;
  </code></pre>
  
  <p>I need to change in the code behind the text "Aguarde..." content that i nested inside the "sAguarde" span, but I don't know how to access this span. The  language is C#.</p>
  
  <p>Many thanks for the help.</p>
