title: enable searching feature from any index ajaxToolkit ListSearchExtender
body: <p>I am using <code>ajaxToolkit:ListSearchExtender</code> in a dropdown. It has the feature "<em>search as you type</em>", like if I type any word it shows the list starting with that word.</p>
  
  <p>But my requirement is that I need the list of all the items that contain the typed word. For example, if I type <em>A</em>, I want all the countries name that contain the word A anywhere. </p>
  
  <p>Currently <code>ajaxToolkit:ListSearchExtender</code> shows only the countries name starting with letter A.</p>
  
  <p>How can I make this ListSearchExtender to search any items in the drop-down that contain the typed word but not just only at the beginning of the item?</p>
  
  <p>Please help!!!</p>
