title: Telerik RadCombobox not keeping state when using client side requestItems() to load
body: <p>I'm using the Telerik RadComboBox control. I have two related combos and when the user selects a value in the first one I filter the second one.</p>
  
  <p>I use the code below to achieve this:</p>
  
  <pre><code>localeCombo = $find("&lt;%= ddlLocale.ClientID %&gt;");
  localeCombo.requestItems(item.get_value(), false);
  </code></pre>
  
  <p>This works totally fine, but when I do a postback my filtered combo resets to the original non filtered list, although all other controls retain their state. I assume this is because the server side list of items is not being updated when I use the client side callback requestItems() function.</p>
  
  <p>Is this the case? Is there a simple way around this?</p>
  
  <p>Any help would be much appreciated!</p>
  
  <p>Thanks</p>
