title: How to trigger Asp:HiddenField OnValueChanged event using JQuery?
body: <p>I have this <code>asp:hiddenField</code> control:</p>
  
  <pre><code>&lt;asp:HiddenField ID="AuxHiddenField" runat="server"/&gt;
  </code></pre>
  
  <p>I would like to trigger its (server side) value changed event using Jquery:</p>
  
  <pre><code>Protected Sub AuxHiddenField_Changed(ByVal sender As Object, ByVal e As System.EventArgs) Handles AuxHiddenField.ValueChanged
      'some logic here      
  End Sub
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>$('#AuxHiddenField').val("Mohaha!!");   
  </code></pre>
  
  <p>Jquery fails to find the element and nothing happens.
  How do I solve this?</p>
