title: Jquery Date Picker arrow key should be prevented
body: <p>I want to force the user to only use the drop down and calendar to
  select a date in the DatetimePicker control.</p>
  
  <p>I do NOT want them to select the control, then use the up and down
  arrow keys to change the date.</p>
  
  <p>How can I prevent them using the arrow keys?</p>
  
  <p>Any help much appreciated.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
         $(function () {
             $(".datepicker").datepicker({
                 changeMonth: true,
                 changeYear: true
             });
         });
         $(function () {
             $(".datepickerApplyyear").datepicker({
                 changeMonth: true,
                 changeYear: true,
                 yearRange: '0+100'
             });
         });
     &lt;/script&gt;
