HTML

<link href="Styles/jquery.datetimepicker.css" media="screen" rel="stylesheet" type="text/css" />
   <script src="js/jquery-1.11.1.min.js" type="text/javascript"></script>
   <script type="text/javascript" src="js/jquery.datetimepicker.js"></script>
   <script src="js/init.js" type="text/javascript"></script>
   <link href="Styles/style.css" rel="stylesheet" />
   <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
   <script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/jquery-ui.js" type="text/javascript"></script>
   <link href="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/themes/start/jquery-ui.css"
       rel="stylesheet" type="text/css" />

If i comments below code, calendar pop-up works.
that code using for nested grid-view, both functionality should work.
