Hi,
When I'm set ngModel directive to the component, the messages are gone when my initial model value is null, empty string or undefined. Is there a way to prevent this behavior? I want to show the messages of the dateInput if the model does not have a valid date.
Here is an example of this. https://dojo.telerik.com/UvAWurud/5. You will be able to see the messages briefly displayed, but then they go away.
Thanks!
Hi,
Today I noticed a wrong behavior with the dateInput.
After the component is initialized with a predefined value, I can't change day part value, the component does not accept them.
In the next dojo you can see if I try to change directly day value, it marks it as invalid value. I need to change it with arrow keys before to accept any value.

Maybe I'm missing something?
Thanks!
I was able to duplicate an issue I found when we upgraded to the latest Kendo UI for jQuery release. The DatePicker is not working correctly when the kendo namespace, kendo.ns, is set. I was able to duplicate it using the MVVM demo example for DatePicker. The month is no longer displayed and clicking on the Month to zoom out in time stops working as well. I have not checked what other functionality is not working. I do know the parsing is working properly as well as formatting.

I have two datetime picker to select a datetime range.
The max value of end datetime picker must be the 00:00 of a
given day (that is only 00:00 of the given day must be selectable).
The min value of end datetime picker depends on the
selection of start timepicker.
Hence I need to dynamically change the minimum value of end
datetime picker while mantaining the max value to 00:00 of the give day as show
in the following dojo link:
https://dojo.telerik.com/IFAWOrax
(based on https://demos.telerik.com/kendo-ui/datetimepicker/rangeselection)
But when you select a different hours from 00:00 on the start datetime picker, the max value of end datetimepicker is not matained.
Dear Kendo UI team,
I have experienced an issue with the Kendo UI datepicker when accessing it with a screenreader on the Kendo UI Vue preview page (https://www.telerik.com/kendo-vue-ui/components/dateinputs/datepicker/):
In the month/year view, if I change the selection, the selected date (from the original view before "zooming out" into the month/year view) is read out.
Expected behaviour: The currently selected month/year should be read out.
Steps to reproduce:
- Start a screenreader (I have tried NVDA and JAWS).
- Focus on the calendar, open it.
- Change the view to the month/year view by using Ctrl+Arrow Up.
- The focus is now on the month/year corresponding to the current date.
- Change the selection by using one of the arrow keys.
- No matter the current selection, always the (whole) current date is read out.
Software versions used:
- Browsers:
- Chromium 77.0.3865.75
- Microsoft Edge 44.18362.449.0
- Screenreader (always initial configuration):
- NVDA 2019.1.1
- JAWS 2019.1906.10 ILM
- OS: Windows 10, latest updates
- Keyboard layout: German
Furthermore, it seems to me that with Microsoft Edge in combination with JAWS I cannot open the month/year view, maybe because of a conflict of keyboard event handlers between the component and JAWS. Also the escape key has no effect, it does not close the datepicker.
The issue also occurs for the original jQuery version.
Thanks for your support.
Kind regards,
Andreas Schütz
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.

Hello,
I would like to request adding a property like DisplayDate which will select the view and value of the Kendo UI DatePicker initially without setting it with the value method.
Thanks!
Bug report
DatePicker Calendar is not visible on Safari on iPad when programmatically set from readonly(true) to readonly(false)
Reproduction of the problem
Dojo: https://dojo.telerik.com/oVoyUSoH
Current behavior
1: Open above Dojo on iPad Safari
2: Click Edit
3: Open DatePicker Calendar
The calendar dates are missing
Expected/desired behavior
Calendar dates shall be visible
Environment
Kendo UI version: 2020.2.617
Browser: [ ipadOS 13.6 Safari ]
- Click the 'Calendar' icon button on the date field. The date picker should pop-out.
- Now whilst the date picker if out change the iPad orientation to Landscape mode.
- Check the date field again. Notice that the Calendar icon button has been duplicated.
The Timepicker portion of Date/Timepicker is showing an odd border and the highlight is slicing that border in half when hovering/clicking within the timepicker. I looked at the timepicker only control, and this border is not showing.
I am attaching the 2 the snippets from dojo.telerik.com for each of the 2 controls to show the display difference.
Bug report
Reproduction of the problem
DateTimePicker in modern type and RTL enabled does not show time selection.
Dojo to reproduce: https://dojo.telerik.com/ABirozos
Expected/desired behavior
Time selection must be available in RTL with modern type
Environment
Kendo UI version: 2020.2.513
jQuery version: 1.12.3

Instead of a drop down for the time choices can they be displayed so the user doesn't have to scroll through a drop down and the choices can be displayed similar to your example on UI for WinForms. Thanks.
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.
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
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.
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.
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");
}
}
...

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.
DatePicker should let developer decide if the chosen day of the month should be persisted from month-to-month. By default the DatePicker remembers the day of the month the user has selected, and that day gets styled differently even when the user navigates away to a different month: the user selects January 12th and then navigates to August, and the 12th day of August is styled differently too. But there are many use cases for a DatePicker where it is not appropriate behavior to remember the previously selected day of the month when the user navigates to a different month. Remembering the day can actually make things confusing for the user in applications where this behavior is not the right behavior.
