title: Get HiddenField in JQuery inside Repeater
body: <p>I have a Repeater control, and I need to access a HiddenField inside. I can't use:</p>
  
  <pre><code>&lt;%= Control.ID.ClientID %&gt;
  </code></pre>
  
  <p>And I can't use the class or cssclass attributes either?</p>
  
  <p>So my question is rather simple, how can I access my HiddenField control inside my repeater?</p>
  
  <p>My scenario is that I populate a multiselectable dropdown, and I need to know in an update function which elements I have selected, for this I use the HiddenField to store the Id's. Then in code behind I can access the HiddenField values and make a propor databind.</p>
