Current behavior

Timepicker components now button in certain situations does not scroll timeselector to current time in adaptive mode.

Expected behavior

We would expect the now button scrolls to current time in all situations, also in adaptive mode .

Minimal reproduction of the problem with instructions

  1. Please run following link: https://www.telerik.com/kendo-react-ui/components/dateinputs/timepicker/adaptive-rendering
  2. Clear timepicker value, there should be "hour:minute PM" in input
  3. Switch to tablet (or mobile) view
  4. Open time selector, it should be positioned to 12:00 AM, because it is min value
  5. Scroll AM/PM selector to PM
  6. Press NOW button
  7. Observe that timeselector did not scrolled to current time (if yes, only by huge accident)

What is the motivation or use case for changing the behavior?

It is obviously buggy behavior, we would like to use now button, but it has to work correctly.

Environment

Browser:

  • Chrome (desktop) version 144.0.7559.133 (Official build) (64-bit)
  • Firefox version 147.0.3 (64-bit)
  • Edge Version 144.0.3719.115 (Official build) (64-bit)

I am using conditional rendering to render a custom editor for the resources in the Scheduler. Even if there is no resource editor the label still renders.

Current behavior

Timepicker component in adaptive mode behaves differently in version 11.0.0 (and above) compared to version 10.0.0 (and above):

  • "Set" button sets value but does not close popup - one more click needed
  • "NOW" button scrolls to current time, but does neither set value nor close the popup - two more clicks needed
  • in the top right corner there is a button with check icon which does the only thing - closes the popup (the same as "Close" button) - it is confusing

Expected behavior

We would expect the same behavior as in the 10.0.0:

  • "Set" button sets value and closes the popup
  • "NOW" button scrolls to current time, sets value and closes the popup
  • there are no two buttons with the same functionality

Minimal reproduction of the problem with instructions

  1. Please run following link: https://stackblitz.com/edit/react-j3smansk?file=app%2Fapp.tsx,package.json and adjust app container width so that the timepicker popup is rendered in the bottom half of the screen, allowing both the popup and the editor to be visible at the same time. 
  2. Repeat previous step for following link: https://stackblitz.com/edit/react-ukfuqrdy?file=package.json,app%2Fapp.tsx
  3. As you can see in "app.tsx" examples are very the same (taken from https://www.telerik.com/kendo-react-ui/components/dateinputs/timepicker/adaptive-rendering), only versions of kendo-react components in "package.json" are different
  4. Observe situations described in Current behavior and Expected behavior sections

What is the motivation or use case for changing the behavior?

We would like to upgrade to 11.0.0 but we do not like this behaviour because it is disturbing, confusing and requires more clicks (time) to work with it.

Environment

Browser:

  • Chrome (desktop) version 138.0.7204.50 (Official build) (64-bit)
  • Firefox version 140.0 (64-bit)
  • Edge Version 137.0.3296.93 (Official build) (64-bit)

System:

  • TypeScript version: KendoReact demos page version
  • Node version: KendoReact demos page version

Hi, 

After pasting a value into the input box of the DatePicker I am then unable to clear it. The value of the DatePicker is correctly set to null, but the value displayed in the input box is unchanged.

Reproduction steps:

1. Open the grid filtering demo,

2. Copy any of the date values from the grid, e.g. 9/20/1996, and paste it into the "First Ordered On" filter,

3. Clear the filter using the clear button.

Result:

The value remains in the input box.

Expected behaviour:

The value should not be visible in the input box.

    The Data Grid does not work properly with large datasets. In the example below with one million records, it is impossible to scroll to the bottom of the grid.

    Firefox: Rows fail to render after scrolling past approximately 200,000 rows.

    Chrome: Rows do render, but the skip parameter never exceeds 745,645 even when the scrollbar is at the bottom, preventing access to the remaining ~254,000 records.

    This contradicts the documentation's claim that the grid "scales from hundreds to millions of records while maintaining a responsive user experience."

    Please see the example - https://codesandbox.io/p/sandbox/silly-wind-tpfg8n

    When column "Unit Price" is locked, while moving the horizontal scroll bar, the group header is sticky (expected behavior), but the group footer is not sticky (wrong behavior).

    We use "@progress/kendo-react-treelist": "^5.10.1" in our project. Trees are usually placed in flexible containers, and users can reduce their size to 0. At this point, we get an error when calling the tableRowsVirtualization function. I have attached a screenshot at the moment of debugging. You can see that the values of items[0] and lastItem are undefined when the container size approaches 0. I didn't prepare an example to reproduce the error, because I think it's pretty clear that an error occurs here. So the questions are: if this is a bug, is it fixed in the new versions of the package? If there is a possible error on our part or it has not been fixed in the new versions, then what should we do to solve the problem? Thanks

    With the ArcGauge component, when you set the rangeLineCap to something other than 'butt' (ie:  round or square), the indicator does not line up with the tick lines.  This leads to misleading values.  Please look at this StackBlitz:

     

    https://stackblitz.com/edit/react-itztql

     

    This will show the comparison between round and butt rangeLineCaps. 

    From the screenshot as well, the ArcGauge on the right looks like the value is greater than 0, resulting in the user being mislead on the result.

    Hi! 

    I have noticed that keyboard navigation doesn't work in the filter editor components inside the Filter component

    Reproduction:

    1. Open https://stackblitz.com/edit/react-rvwjsm?file=index.html
    2. Choose "name" or "price" from the first dropdown
    3. Type anything in the input field
    4. Try to change the cursor position in the field using arrow keys - doesn't work

     Is there a way to enable it or go around it?

    I am using KendoReact 10.2 and I am getting several warnings about deprecated Sass methods and syntax including one that is causing an error in the browser and blocks rendering. I used the sass-migrator to try to migrate these methods.

    Please upgrade KendoReact so it can work with the latest Vite, React and scss/sass packages without deprecation warnings and errors.
    Also fix the React version dropdown in this feedback form. It doesn't show React 19 as an option.

    If TabStrip animation is set to false, TabStripTab content width is 100%. If TabStrip animation is set to true (default), TabStripTab content width depends on the content and TabStripTab.contentClassName has no impact on the width of the content.

    We should not have to override css classes to set the TabStripTab content width to 100% with animation enabled. As a result we have disabled TabStrip animations everywhere.

    Hello,

    there are numerous problems with navigating / scrolling on the DataGrid using keyboard keys.

    Here is the test page:

    https://stackblitz.com/edit/react-brdhufzd

     

    1. Grid with navigatable=true:

    - arrow keys - when you select a cell to be able to navigate and then  keep pressing down and then up, it's not posible to come back to the first record. You need to use the mouse.

    - Page up/down keys work the other way round, also sometimes is not possible to come back to the first record, the scrollbar does not show the current position.

    - It starts to work correctly after using the arrow keys and page up/down keys alternatively couple of times

    2. Grid with navigatable=false:
    - arrow,Page up/down keys and scrollbar work correctly

    3. Grid with navigatable=true and nested inside Window:
    - works the same way as not nested - the same problems occur

    4. Grid with navigatable=false and nested inside Window:
    - arrow keys move the window instead of navigating the grid
    - Page up/down don't work at all

    In Multicombobox choosing combo element using keyboard is broken when data source contains more than one duplicate value of a property used as a textField.

    Steps to reproduce:

    1. Open https://stackblitz.com/edit/react-afvets8p?file=app%2Fapp.tsx

    2. Try to select the 4th value using the arrow keys.

     

    It's impossible because there are two items with the name 'Guy Wooten,' and this field is used as the textField.
