title: Find previous value of drop down list on change event
body: <p>I have drop down list declared like :</p>
  
  <pre><code>    &lt;asp:DropDownList ID="myDropDown" width="300" CssClass="textboxda" 
  AutoPostBack="True" runat="server" onmousewheel="return false;" /&gt;
  </code></pre>
  
  <p>Drop down list change method </p>
  
  <pre><code>myDropDown.Attributes.Add("OnChange", "return OnChange();");
  
  
  function OnChange()
  {
      var $j = jQuery.noConflict();
  
      var sel = $j(this).prevAll("#myDropDown:first"),
        val = sel.val(),
        text = sel.find(':selected').text(); 
  
      alert(text);
  }
  </code></pre>
  
  <p>I am populating this drop down dynamically.</p>
  
  <p>I am fetching the last/previously selected text of the drop down, but this is not working.</p>
  
  <p>Please suggest.</p>
