set date and time in jquery datetimepicker based on another datetimepicker

It works properly until any postback of control fired but when any postback event of control fire and then if we change "from date" than in "to date" datetimepicker it only shows date instead of date&time. same when I change "to date" than in "from date" datetimepicker it only shows date instead of date&time.it looks like it reset datetimepicker onClose(); I have also tried to set minDateTime and maxDateTime property but still, issue does not resolve.I am using jqueryUI datetimepicker

Solution

  • you can do that using below setting. use dp.change method

    $(function() {
   $('#datetimepicker1').datetimepicker();
   $('#datetimepicker2').datetimepicker({
      useCurrent: false
   });

   $("#datetimepicker1").on("dp.change", function(e) {
      $('#datetimepicker2').data("DateTimePicker").minDate(e.date);
   });

   $("#datetimepicker2").on("dp.change", function(e) {
      $('#datetimepicker1').data("DateTimePicker").maxDate(e.date);
   });
});
