When I incell edit multiple rows I only receive a sync callback through `change` on the datasource for the last row with only that last row in the "changedItems". This results in the grid not removing the dirty indicator for any of the other rows, only the last one is removed. The rows are updated properly and I if I were to manually call grid.refresh() it removes the indicators. If I update the rows individually it has no problems.

Here I've updated only the first row:

Here I've updated only the second row:

Here I've updated the first 2 rows at the same time and only the last one is detected as updated:

Here I've updated the PRS column for all 4 rows to "5" and it saved correctly, but only the last row is detected as updated in the grid:

As there's a lot of code involved I can't just paste it here, I can provide snippets or information about particular settings though.

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.

Hello, 

- I reproduced my problem on this DOJO https://dojo.telerik.com/EpUVIxek , columns are not on the same position with the category because I have 5 column series and 4 of them are 0 in one category.

The observed appearance is due to the data with zero value for each series. Even if the value for a series/bar is zero still there is a placeholder in the Chart for the respective bar. Hiding the data points with 0 value is not supported in the Kendo UI Chart and I am afraid I could not suggest a possible approach for achieving such an appearance. 

Can something be implemented so the columns with 0 value to not take place?

Best regards.

Hi Guys

Just testing the latest release and have spotted an issue with the DatePicker & DateTimePicker controls whereby the next month transitions are very sluggish.

To demonstrate run the Overview demo

    https://demos.telerik.com/kendo-ui/datepicker/index

Clicking on the 'Previous' month button the transition is nice an smooth but clicking on the 'Next' month button things are very sluggish with a snap effect.

Problem occurs under both Chrome & Firefox so not browser related.

A quick check back through previous releases and it would appear this regression was introduced with the v2024.2.514 release.

Regards
Alan

I have custom messages for my filter, these values replace the and/or values instead of just the visual after switching the and/or once.

Reproducer: https://dojo.telerik.com/AdOGEQey

When initially running you will see "en/of" (and/or), if you than press any of them the text below will insert the message value of the button rather than the underlaying value of "and/or".

Hi,

We have recently upgraded our Kendo MVC version to 2024.2.514.462. The normal upgrade works fine but I was trying to implement the `CSP template` after removing the `unsafe-eval` from the tag as it was announced in 2023 version.

I was following the example given in CSP template and tried changing the template defined in treeview (also as shown in the documentation):-


  sideNavList.kendoTreeView({
      /*template: "<span id='#= item.id #' class='navText'> #= item.text# </span>",*/
      template: ({ items }) => `<span id='kendo.htmlEncode(items.id)' class='navText'> kendo.htmlEncode(items.text) </span>`,
      dataSource: hierarchicalLeftNavData,

It is not throwing error but it's not able to recognize the `item` and rendering the template as:-


<span id="kendo.htmlEncode(items.id)" class="navText"> kendo.htmlEncode(items.text) </span>

Am I missing anything?

Hi Guys,

I have been investigating an issue with the ComboBox component under Chrome whereby a scrollbar is being show when using the autoWidth option and a limited number of list entries.

The scenario is as follows

- When the control initially loads and you hit the dropdown button the list does not have vertical scrollbar.
  (See screen shot 1)  

- Select an item and and then hit the clear button.
  Now when you hit the dropdown the list has a vertical scrollbar.
  (See screen shot 2)

The issue is very random and can occur with any number of list items, providing the initial dropdown doesn't require a scrollbar.

I have tried to create a dojo to illustrate the problem but have so far failed.

Looking at the element with Dev tools I see on the initial dropdown the wrapper div is as follows

    <div class="k-list-content k-list-scroller" unselectable="on" style="overflow: hidden auto;">

but after select, clear & dropdown the div shows

    <div class="k-list-content k-list-scroller" unselectable="on" style="overflow: hidden scroll;">

Tracing through the code the problem is within the following function of the kendo.list.js file

        _refreshScroll: function() {
            var listView = this.listView;
            var enableYScroll = listView.element.height() > listView.content.height();

            if (this.options.autoWidth) {
                listView.content.css({
                    overflowX: "hidden",
                    overflowY: enableYScroll ? "scroll" : "auto"
                });
            }
        },

It would appear that under certain conditions Chrome is setting the enableYScroll value to true and hence the 'scroll'.

Looking at this function I cannot see a reason why there is even a need to set overflowY to 'scroll' surely just leaving it set as 'auto' is good enough and let the browser decided if scrollbars are required.

Regards
Alan

There is an issue with the .k-sorted class being applied to the last column in the grid when the actual column is not visible. It also is not updating the k-sorted when a sort is applied after the grid was created. 

This seems to be an issue in the latest release if the column sorted on is hidden, the last column in the grid gets the class. I also noticed that sorting a column does not apply the k-sorted class to the correct column: https://dojo.telerik.com/@dojolee/eFIbaSUn

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.

We are currently utilizing Telerik's Spreadsheet functionality across two different technologies:

- KendoUI for jQuery: This is being used by our FrontEnd users.
- .NET Assembly of Telerik: This is employed for backend processing and interfaces.

Both Spreadsheet implementations allow us to populate data; however, we've observed a discrepancy between the two. Specifically, there is a misalignment in the available functions, where some functions accessible in KendoUI are not available in the .NET Assembly. To address this inconsistency, we request the following enhancements:

1. Unified Function List: We would like an official list of functions that are consistently supported by both the jQuery library and the .NET assembly. Currently, the frontend offers a broader range of functions than the backend. Since our system relies on both for computations, consistency is crucial.

2. Function Usage Detection: We request an event or function in both the JS and .NET implementations that can detect the functions used within a formula. This will allow us to identify discrepancies early on.

3. Backend Validation: An event that triggers when a formula entered on the frontend is valid there but would fail on the backend due to unsupported functions would be invaluable. This will help prevent issues caused by discrepancies between the frontend and backend function implementations.

4. Enhanced Backend Functionality: We also request additional functions or exposed properties on the backend to perform similar checks as described above. This is particularly important for our customizations that allow formulas to be entered directly on the backend, bypassing the spreadsheet UI.

5. Specific Error Handling: On the backend, it would be helpful to introduce a specific error type, distinct from the generic error, that indicates a calculation failure due to an unsupported function in a formula. Currently, the generic error type could indicate multiple issues, making it difficult to diagnose the root cause.

See https://demos.telerik.com/kendo-ui/menu/scrollable

When you hover over the left or right arrow on the menu, the menu scrolls.

Our client *hates* that, and only wants the menu to scroll when you actually click on the left/right arrow.

 

Request:

Add an option so that we can turn OFF the scrolling on hover on the left/right scroll buttons in the menu.

In the jquery scrollView component https://docs.telerik.com/kendo-ui/api/javascript/ui/scrollview there is no current way to enableto 'endless' or 'wrap around' option like the react component has

ref: https://www.telerik.com/kendo-react-ui/components/scrollview/endless-scrolling/

Requesting that this feature be added.

 

For my SPECIFIC my use case (which will probably not work for everyone), I did add a workaround for now

(not fond of it as it relies on the implementation details of the current version)

 

In our SCSS, I added an override to force the previous/next buttons to always be visible, even after the control hides them


...
		&.k-scrollview {

			.k-scrollview-prev, .k-scrollview-next {

				//Prevent the control from hiding these buttons when it reaches the 'end'
				//We will be using some custom logic to force the 'wrap around'
				display:flex !important; 
...

Then I subscribed click events and did some manual handling on the buttons

//After the page load & scroll view is initialized...

//note: $slides is a jquery instance that the scrollView is attached to
let scrollView = $slides.data("kendoScrollView");

let $prev = $slides.find('.k-scrollview-prev');
let $next = $slides.find('.k-scrollview-next');
$prev.on("click", function (e) {
	// NOTE: Here we are looking at an 'internal' variable, this is dependent on the version of Kendo we are using - may need to change
	// in the future
	// I figured this out by looking at the implementation in the source
	//		\src\js\kendo.scrollview.js
	let pageCount = scrollView._content.pageCount;
	let currentPage = scrollView._content.page;
	if (pageCount > 1 && currentPage === 0) {
		e.preventDefault();
		e.stopPropagation();
		scrollView.scrollTo(pageCount-1);						
	}
});

$next.on("click", function (e) {
	let pageCount = scrollView._content.pageCount;
	let currentPage = scrollView._content.page;
	if (pageCount > 1 && currentPage === pageCount - 1) {
		e.preventDefault();
		e.stopPropagation();
		scrollView.scrollTo(0);						
	}
});

Two issues, both relate to using the Org Chart control to visualize a large dataset, e.g. 4000 items, with 2000 items on one level.

1) Expanding a node gets VERY slow when expanding, taking several minutes to complete -- Is there anything we can do (short of partitioning the data) to make this go faster?

2) When expanding a large number of nodes, the chart gets unweildy.  For example, if I have a top node, then five nodes below that, and expand one of those five nodes, it spreads out every node on the second row, even though only one of those nodes needs to be spread out to allow room to display the nodes under it. --  Is there anything we can do to keep the display more compact, and avoid unnecessary spreading?  (See attached for example.)

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 running into an issue with allowing copy/paste of dates into the filter and cell input fields. Currently, the date fields have validation to support MM/dd/yyyy, and users of the app may be trying to copy dates in that are MM/dd/yy. I would expect Kendo to auto format the date to MM/dd/yyyy after the paste happens, or at least allow support for that, but it doesn't seem to happen.

In the cell, when putting in MM/dd/yy, a validation message appears saying the date is invalid, and there doesn't appear to be a way to override that. In the filter, when putting in MM/dd/yy and submitting the filter, it doesn't stick and completely ignores the date put in.

Steps to reproduce (filter):

  1. Copy a date formatted as MM/dd/yy
  2. Paste it into a date column filter
  3. Attempt to apply filter
  4. Notice that the filter is ignored

Steps to reproduce (cell edit):

  1. Copy a date formatted as MM/dd/yy
  2. Paste it into a cell datepicker field
  3. Notice the validation flags it as an invalid date

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
