title: datepicker undefined is not a function
body: <p>I am making an app in asp.net and I am using DataList. I want to add datepicker (jquery) in my app. I have created MasterPage2 and added javascripts and css</p>
  
  <pre><code>&lt;link rel="stylesheet" href="css/layout-admin.css" type="text/css" media="screen" /&gt;
      &lt;link rel="stylesheet" href="css/jquery-ui.css" type="text/css" media="screen" /&gt;
      &lt;script src="js/jquery-1.10.2.js" type="text/javascript"&gt;&lt;/script&gt;
      &lt;script src="js/jquery-ui.js" type="text/javascript"&gt;&lt;/script&gt;
      &lt;script src="js/jquery-1.5.2.min.js" type="text/javascript"&gt;&lt;/script&gt;
  
      &lt;script src="js/hideshow.js" type="text/javascript"&gt;&lt;/script&gt;
      &lt;script src="js/jquery.tablesorter.min.js" type="text/javascript"&gt;&lt;/script&gt;
      &lt;script type="text/javascript" src="js/jquery.equalHeight.js"&gt;&lt;/script&gt;
      &lt;script type="text/javascript"&gt;
          $(document).ready(function () {
                  $(function () {
                      $("#txtData").datepicker({
                          showButtonPanel: true
                      });
                  });
              $(".tablesorter").tablesorter();
          });
  </code></pre>

                  &lt;fieldset&gt;
                      &lt;asp:TextBox  ID="txtData" runat="server"&gt;&lt;/asp:TextBox&gt;
