For the datepicker control, it would be great if it could support relative values for the min and max range like the jQuery datepicker does.  For instance, you can set minDate: 0, which is today.  Or you can say maxDate: "+6M" for a max date of 6 months from today (as in their documentation: https://api.jqueryui.com/datepicker/#option-maxDate).  These generic expressions make it much easier to set restrictions.

Date picker when entering the day or day and month to autofill the content with current year or current month and year, same as asp.net ajax datepicker

Is there any possibility to add a new property to the datepicker that will let the user to use a datepicker like the ones used in materializecss framework?

Sample here:
http://materializecss.com/forms.html#date-picker

when mouse click in a kendoDatePicker, control will auto choose date part at clicked position, and we can use left and right arrow to go to another date part, use up and down arrow to cycle through all possible value of that part, or input number (month name in the case) directly instead

It would be helpful if when entering a date into a datepicker control you could just type +7 to have it select 7 days from today.  Or -5 for 5 days ago.  Or if you just type 0, it would select today.  Or type 15 and it would select the 15th of the current month.  This would make keying in dates much faster than using the calendar.

Optionally allow for the disabling of Daylight Savings time detection when using the DateTime picker, or to set the TimeZone for the picker manually.

The current date time and date-time pickers don't allow for scrolling the data using the mouse scroll. 
This functionality is available in ajax controls this makes a mix web site not consistent in behavior of controls.

Currently when creating a Date/Time Picker object by using the time in milliseconds since 01.01.1970 UTC the Date/Time Picker works perfect.

When trying to submit a form containing a Date/Time Picker, the widget will submit the formatted time/date instead of the milliseconds since 01.01.1970 UTC.

There is a workaround to extend the onChange Event and manipulate the value of the input field manually. This might solve the technical problem but now the UTC milliseconds will be displayed inside the widget.

Might it be possible that the widget formats the display date/time and keeps a hidden input field for storing the value? It is actually not possbile to use dates/times in UTC milliseconds with this widget allthough the JavaScript Date object can handle it.

Provide properties to set min/max time of the DateTimePicker, e.g always shows from 8AM to 5PM of everyday.

In a filter input field I had one blur event
to fix a entered date string.
It wasn't called if the users hit "Enter" instead of cliking the Filter button or hitting TAB which
would cause a blur event.

T. Tsonev asked me to post this to "UserVoice portal":
Maybe an event that is triggered before attempting to read the value from the input.
This will consolidate both handlers in your case.


Below are the two handlers to fix an input field if a blur or Enter key is done/hit:

---

If an input field is changed and the user does a blur (TAB or clicks filter button) after
entering a date
or
hits the enter key without doing a blur.
the FixDate function is called and input field is changed
before the filter popup is submitted
and the Filter works if a date like this is entered:
11/9/2004 0:0
FixDate canges to:
11/9/2004 12:00 AM.

Below is the code I changed:
See the sections with "Fix "
comments.

Maybe they need a on "blurOrEnter"
event so you don’t need to make two tests?  (((, or an event that is triggered before attempting to read the value from the input)))
...
               // Fix - Modified to call a FixDate function.
               // Test for a blur (ie: click or tab to another widget and leave the input field)
               // NOTE: blur doesn't happen when the enter key is hit
               $("[data-role=datetimepicker]").on("blur", function()
               {
                    var element = $(this);
                    FixDate(element);
               });
     
               // Fix - Modified to handle the "Enter" key
               //       and call the FixDate function
               //       to modify the input field from "11/9/2004 0:0" to 11/9/2004 12:00 AM"
               //       before the form is submitted.
               //       This makes the filter work when the enter key is hit
               //       which doesn't cause a blur to happen.
               $("[data-role=datetimepicker]").on("keydown", function(e)
               {
                    // Test for Enter key
                    if (e.keyCode == 13)
                    {
                         var element = $(this);
                         FixDate(element);
                    }
               });
          }
     });

     // Change the date in the filter input field by using 
     // Datej Date.parse.
     // This will change strings like: "0:0" 
     // To: "1/29/2015 12:00 AM"
     // and allow the filter to work
     function FixDate(element) 
     {
          // Get element for datetimepicker
          //var element = $(this);
          // Get widget for datetimepicker
          var widget = element.data("kendoDateTimePicker");

          // See if element has changed
          if (element.val())
          { 
               // Set Text of widget to a Datejs string date from the elements text
               // IE: 11/9/2004 0.0 will be 11/9/2004 12:00 AM
               widget.value(Date.parse(element.val()));

               // Fix by T. Tsonev 01/26/2015
               // make a change happend so new text is used.
               // ie: Use "11/9/2004 12:00 AM" instead of "11/9/2004 0:0"
               widget.trigger("change");
          }
     }

It would be good if the datetimepicker would allow starting weeks from Monday. This is the standard in certain areas.

Mobi scroll already provides this kind of selection (http://demo.mobiscroll.com/calendar/calendardatetime/#)

but mobiscroll does not offer the full support of a schedule that kendo UI does. But oh how sweet it would be if Kendo also provided support for scrolling. 

As far as UX/UI is concerned picking a date and time via slot machine scrolling style is much easier to do on a mobile device.

Thanks!

I get people complaining at the length of lists for timepicker inputs, especially if using small minute intervals.
How about an alternative input mode that allows for faster and simpler input.

This method is great - visual, intuitive and quick.

Few others out there all with pros and cons

Add the feature to be able to walk through date, hour, and minute selection in a stepped fashion, similar to the functionality of this DatePicker:

http://www.malot.fr/bootstrap-datetimepicker/demo.php

The gist is to first allow for day selection. Then, with the popup still open, give the user the ability to select the hour of the day, and finally the particular minute of that hour.

It would be great to allow custom configuration of Time drop down in DateTimePicker control.
Since most occurrences in normal system will take place between normal business hours (7am - 6pm), it would make sense to have the time dropdown start at 7am and then go on from there so it would be:
7am 8am 9am .... 4pm 5pm 6pm ...... 12am 1am etc.
This would improve user experience by putting the most commonly selected times first in the dropdown list and reduce the scrolling the user has to perform.

I'd like to be able to specify a custom date in the datepicker footer rather than "today".  In financial end of day applications you often want to select the previous business day e.g. the "close date".

date picker should allow read only of text box

The datepicker does not validate the year when selecting a date and prepending the year with a number. However if you put any character after the year it is stripped off. It would be understandable to allow dates that are longer than 4 digits but the picker only goes to 2099.

This causes the date to be returned as null.

Please take a look at https://github.com/dangrossman/bootstrap-daterangepicker

It would be nice to have similar option in DatePicker - to choose range of days.

Globalized applications use the DateTimeOffset type instead of DateTime since it includes the offset from UTC for different time zones. If DateTimePicker could bind to this type it would simplify UI development. It would have to have the offset or timezone value provided as either a property or as a second binding.
