Hi,

I've notice an issue with Scheduler: the height for group slot is not correct calculated and items goes down to the next group slot.

Scheduler :

   - group vertical after a field

   - type of scheduler: "timelineWeek" or "timelineMonth"

   - items of the group have same start date and their number are bigger then 20.  

kendo ui version: 2020.1.219. Same issue with 2021.1.119

----------------------------------------------------------------------------------------------------------------------

I've created a dojo as example:  https://dojo.telerik.com/EHeNigIQ  .   Also, you can see the issue into the picture bellow.

You can modify the variable  "rows = 30;"  and you will see more items that goes wrong into the other group slot.

Follow steps in sample at https://dojo.telerik.com/@GaloisGirl/OJUPoYOY/8

  • Actual result: the call to "create" has no information that the new folder should be created in "folder 1"
  • Expected result: the call to "create" should contain information about the path, for my back-end to create an entry in the correct place

In current versions of Firefox, scrollbars do not longer reserve any space. In grids with locked columns, this leads to a double border at the right end of the grid's header:

The problem only appears if locked columns are present and scrollbars use zero-width (Firefox-Default). This DOJO contains a minimum reproducible example.

To reproduce the issues, open this DOJO that just renders a grid in a dialog.

  1. open the dialog
  2. focus the "Add" button
  3. press TAB until the focus is on the first cell
  4. press ARROW DOWN (this focuses the checkbox in the cell below)
  5. press TAB

-> the close button of the dialog is focused

Views - Month - numberOfWeeks (set to 6 weeks), do not need to see previous or next month week.  Only show days of the selected month.

This is OK:

This is not, unnecessary week of Aug 03.  The extra week adds to a busy calendar clutter.

Hi Guys,

Just upgrade to the 2025.1.211 release and during testing I have spotted a fundamental issue which should have been picked up during QA.

Run the following dojo

    https://dojo.telerik.com/dBSXoLYq

Open up the filter menu on the date column and hit the icon and you will find the date pop-up is constrained within the filter menu and cannot be navigated.
See attached screenshot - DateFilter.png

Note: This also effects filtering Date Time columns as well

Is there a workaround for this or do we have to wait another couple of months for the next release because as things stand we cannot pushed this to production.

Regards
Alan.

Hi Guys

Have just tripped over the following issue whereby blur events are not being trigger when using combobox clearButtons.

To demonstrate please run the following dojo

    https://dojo.telerik.com/aDeVamaQ

and carry out the following.

1) Clicking between ComboBox1 & ComboBox2 shows that onBlur events are being triggered correctly.

2) Now select items for both ComboBoxes then click between ComboBox1 & ComboBox2.
   Once again onBlur events are being triggered correctly.

3) Now click on ComboBox1 to set focus and then click on the clearButton in ComboBox2.
   ComboBox2 receives focus and clears the data but ComboBox1 never triggers an onBlur event.

I don't believe this a new regression but something that has been kicking around for some time that hasn't been picked up by your internal testing or being spotted in the wild ... Until now that is.

Regards
Alan

While migrating my app away from v2023.3.1010 (the last release with AngularJS bindings) to the latest v2024.2.514 version, I have tripped over an issue whereby the 'lockable' property is being ignored.

To illustrate run the following dojo

    https://dojo.telerik.com/ovaHinas

and you will see the 'Object ID' and 'Ship Name' columns can be dragged and unlocked.
Likewise any unlocked columns can be dragged and made locked.

Looking back over previous versions this regression was introduced in the v2023.3.1114 release.

Dear support team,

when using the gradient color selection for font color and/or background color the textbox for the HEX value seems to be "disabled".
It can not be selected by using the mouse but it works using keyboard navigation, so the TAB key.

This can be reproduced easily with the samples in the API documentation (https://docs.telerik.com/kendo-ui/api/javascript/ui/editor/configuration/tools.palette) of the editor or the main demo by changing the "foreColor" or "backColor" tools to 

{
   name: "backColor",
   palette: null
}

or see the following dojo containing the default : https://dojo.telerik.com/IbaFaGIz

This is annoying in case you have an exact color that should be used as it is awkward to select it in the "color area".
The textbox should be fully useable by the users.

PS:
Same when switching from HEX to RGB input.

Hi,

I'm finding that the grid pager is improperly rendered when it's initialized while hidden. Regression was introduced in version 2023.2.829 (didn't check internal revisions).

I use this, for example, when using tab panels and switching tabs containing grids.

 

I've made a dojo that illustrates the issue, clicking the button "show grid" shows the previously hidden grid

https://dojo.telerik.com/AZADekem

 

Best,

Gil

If a column is hidden in a grid, editing and then closing the popup shows the column for that row.

Hello,

I am experiencing a bug on my kendo grid filtering when doing a filter on the column with foreign keys.

In the filtering popup, the 2nd dropdown to select value is always empty and there is no data associated with the dropdown.

You can also see this bug on yoru demo site:

https://demos.telerik.com/kendo-ui/grid/foreignkeycolumn

Here i am trying to filter by category and the first dropdown has data in it, however the 2nd one doesn't.

Please advise,

 

Thanks,

 

Vlad

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.
