We have a column in our grid bound to a complex JSON object. When a different column's value is changed, we need to change the nested properties in the complex JSON object.

To do this, in the grid's Save event, we are calling model.set("theComplexObject.NestedProperty", newValue). However, doing this does not automatically update the UI for that row's cell. Furthermore, it never seems to mark the column dirty. Manually calling grid.refresh() will fix the issue, but the grid we are working on has a lot of columns and it adds a performance hit.

This approach works for all of our other columns that do NOT use complex objects. They correctly show the dirty flag and new model value after the save operation completes.

Below is a Dojo example with the save event wired up and a complex name column. It's worth mentioning that the dirty flag also doesn't appear to be working on the eye color column. This may be another bug introduced in a newer version of Kendo.

https://dojo.telerik.com/ZHkxwJee

  • Change the age for a column and click off the cell. The eyeColor updates, but the name does not. The dirty flag gets put in the first cell for some reason (this happens when updating the second row too... it adds the dirty flag to the first cell in the first row).
  • Enabling the currently commented line that does e.sender.refresh() will fix the display issues, but the dirty flag still doesn't show for the name column.

Hi team, 

I think there is a bug in the dependency detection.

In the attached "config_buged.js" i have chosen some components. The component "chiplist" was partially checked due to dependency.

When lunching my application I got the error :

Message: e(...).kendoChipList is not a function
    at init._createList (kendo.custom.min.js:91:8505)
    at new init (kendo.custom.min.js:91:3218)
    at init._attachGroupable (kendo.custom.min.js:133:96797)
    at init._groupable (kendo.custom.min.js:133:96348)
    at init._continueInit (kendo.custom.min.js:133:33864)
    at new init (kendo.custom.min.js:133:33735)
    at HTMLDivElement.<anonymous> (kendo.custom.min.js:1:42737)
    at jQuery.each (jquery-3.1.1.js:368:19)
    at jQuery.fn.init.each (jquery-3.1.1.js:157:17)
    at e.fn.<computed> [as kendoGrid] (kendo.custom.min.js:1:42713)

 

I was forced to totaly check the "chipList" component as seen in the attached file config.json

The Kendo-UI Diagram widget supports moving the whole diagram using the pan() method. However, the given offset does always have to be absolute.

Consider the following example:

The diagram is zoomed in and therefore not fully visible - assume a current offset of (-100, -100). The users should be able to pan using keyboard shortcuts. Whenever pressing one of the arrow keys, the diagram is moved in the corresponding direction by e.g. 50px:

If the user presses [ArrowRight], pan() needs to be called with an offset of (-50, -100).
If the user presses [ArrowUp], pan() needs to be called with an offset of (-100, -150).

However, since I do not know how much the diagram has already been moved, I cannot set the absolute offset required.

I have seen that pan() returns the current offset when being called without arguments, but this is not documented. Is this safe to use for that purpose or is there a better alternative? If yes, the documentation should be updated.

https://dojo.telerik.com/yBSdUQYS demonstrates the issue:

When a grid detail row is expanded, and pushUpdate() is called on it, the row collapses.

What is expected is for the grid row to remain in its prior state (expanded or collapsed.)

Until this is fixed, is there a work-around, other than manually re-expanding the detail row(s)? This is not a feasible work-around in which multiple nested grid rows are collapses and re-expanded, as this causes the UI to jump unexpectedly for the user.

Hi Guys

While upgrading and testing the latest 2024.4.1112 release I have noticed the loading indicator, for both the ComboBox and MultiColumnComboBox, has moved from the dropdown button to inside the edit control.

Is this a a bug or a design decision?

If it is the latter I can find no mention of this breaking change in the release notes, or were you hoping nobody would notice?

To me the old design whereby the loading indicator replaced the dropdown arrow was more logical giving the impression to a user the button was unavailable.

So my finial question ... How do we get the old functionality back?

Regards
Alan

i've tried to apply autoFitColumn method for treelist accordingly to the documentation, https://docs.telerik.com/kendo-ui/api/javascript/ui/treelist/methods/autofitcolumn#autofitcolumn , and seems it assumes only "simple" columns structure, i.e. no nested headers.

Hi Guys,

Have just tripped over the following whereby html escaped title data is being shown in the Excel column headers when the grid is exported to Excel.

To illustrate the problem run the following dojo

    https://dojo.telerik.com/AwUMarUl

As you can see the first column title is not shown due to the angled brackets
The second column has the angled brackets escaped so the title shows correctly in the grid.

Now when the grid is exported the column headings are as follows:

    <Product Name>  &lt;Unit Price&gt;

which is not what is expected ... Any & all html escaped characters should be un-escaped.

Regards
Alan

I am trying to upgrade my Kendo UI JQuery installation from 2022 to 2024 and it is not going smoothly. One issue I'm having is that now my grids with locked columns do not span the whole width of their container. In the old version, the k-grid-table would expand to fill the width of the k-grid-content but now it seems that the columns retain their width, rather than growing like they used to. So now there is a large white space between the last column and the vertical scrollbar. I did notice that if I remove the inline style in the developer tools that is applied to the k-grid-table in the unlocked section, it fixes it. It should continue to expand all columns evenly to fill the available width like it did in versions past or this should be an option that the user can set. To leave that space without any user choice is a bug.

Old Version:

New Version: 

 

Note, I reported this in a forum post. I know I can write code as a workaround but that is cumbersome, especially when I have many grids and multiple developers working on the project.

In the latest version of Kendo UI, various input controls like the NumericTextBox or the ColorPicker now consist of an input field and a button control (used for increasing/decreasing the value or opening the dropdown).

The border-radius for those widgets can be controlled by setting the "rounded" option. At the same time, when using SASS themes, a button's default border-radius might be set using the $kendo-button-border-radius variable. The buttons inside e.g. a NumericTextBox do not override the theme's border-radius which leads to an outcome like this:

Widgets that use Buttons internally (and therefore offer no way of overriding the button's border-radius by setting its "rounded" option manually) should override the default styles.

Unfortunately, I could not reproduce the behavior in a DOJO, because I cannot transpile SASS themes there.

add delay parameter in miliseconds for the kendo.ui.progress so you don't see your container blinking if your ajax calls are fast.

Context: There is an item that illustrates the issue here: https://www.telerik.com/forums/kendo-datepicker-value-not-populated-after-refresh-firefox-only

In Firefox, when using the asp-for tag helper to bind a c# DateTime field to an input element, then calling kendoDatePicker() on that element, the control fails to populate on a soft-refresh (F5). Upon reloading using F5 in Firefox, the input's type is set to datetime-localand the input 's control variation is changed to the default date picker.  Then, the Kendo UI DatePicker is initialized with a blank input which normally has a type of text

Example project and video of issue are attached.

This is the pertinent code (also happens in latest version of Kendo as well):

    public class IndexViewModel
    {
        public DateTime DateAsDateTime { get; set; }
    }
        public IActionResult Index()
        {
            return View(new IndexViewModel { DateAsDateTime = DateTime.Today });
        }
@model IndexViewModel

<input id="dtDate" asp-for="@Model.DateAsDateTime">

<script type="text/javascript">
    $(document).ready(function () {
        $("#dtDate").kendoDatePicker();
    });
</script>

Bug report

The DropDownTree allows us to configure its checkChildren and filter options. Both options are working correctly, when used separately.

When the two options are defined for the DropDownTree, the checkChildren options don't select the child elements of a given node that is checked.

Reproduction of the problem

  1. Open this Dojo example
  2. Expand the DropDownTree popup
  3. Check the "Furniture" node checkbox

Current behavior

Only the "Furniture" checkbox is being checked

Expected/desired behavior

The "Furniture" and all of its child nodes should be selected when clicking on the "Furniture" checkbox.
Here is a Dojo example in which the checkChildren configuration is working as expected.

Environment

  • Kendo UI version: 2022.1.412
  • jQuery version: x.y
  • Browser: [all]

Hi,

When I double click a cell and enter into editing mode, scrolling up or down will make the editor div out-of-place. 

It should follow the target cell instead.

This can be easily reproduced here: https://demos.telerik.com/kendo-ui/spreadsheet/index

It seems Kendo UI for Angular/React also have the same issue.

Hello Team,

 

We are currently facing challenges with the Kendo grid, which is a widely used widget or component at o9Solutions. Although we have been using Kendo for a long time, the widget is failing to meet accessibility standards for some components, which are crucial in today's world.

 

Regarding the Kendo grid, there is an issue where SR is reading the table twice, once for the header and once for the cells. This can cause confusion for assistive technologies like SR.

Consider the cases of horizontal scroll or fixed column cases also.

Having a single <table> is the standard. We can't create multiple tables, which will violate the good coding practices + accessibility standards.

---

I saw some posts regarding this... where it was mentioned we can remove this Scrollable() . But what are the cons of this if we remove this?
--

 

We want this functionality like a horizontal or vertical scroll or fixed column cases.But it needs to recognize as a single table.

Currently, the kendo.culture() method accepts only a string argument which is used for mapping an included culture file.

However, it would be beneficial if additional arguments could be passed to the method as well which may override some of the culture file's existing options. For example:

kendo.culture("bg-BG", {
   numberFormat: {...},
   calendars: {...}
})
