Create a grid with batch set to true and update a field value using the set method of the kendo.data.Model object in JavaScript. The grid cell will be marked as dirty but the "Save changes" or "Cancel changes" buttons will not display. If you click into another editable cell, then the buttons will display.

See https://dojo.telerik.com/TwTMSsrB and attached example.html.zip.

If you create a grid with editable set to true, selectable set to one of the multiple options ("multiple, row" or "multiple, cell"), batch set to true and a column with editing disabled (either through the model or through the columns editable property), then when you update an editable cell and click the non-editable cell in the same row the "Save changes" and "Cancel changes" buttons do not appear.

See https://dojo.telerik.com/zAKmmTEU and attached example.html.zip

Notes:

Editable is disabled using a JavaScript function for UnitsInStock

{ field: "UnitsInStock", title: "Units In Stock", width: 120, editable: function() { return false; } },

Editable is set to false in the schema model for Discontinued

Discontinued: { type: "boolean", editable: false },

 

In this example, if you change the value of a UnitPrice cell and then click one of the non-editable cells (UnitsInStock or Discontinued) in the same row, the UnitPrice cell will be marked as dirty, but the "Save changes" and "Cancel changes" buttons will not appear.

This appears to happen because of the following:

  • The focusout event is triggered on the grid.
  • The closeCell method is called from the tap event registered on the cell.
  • The _destroyEditable method is called within the closeCell method.
  • The _editContainer field is set to null in the _destroyEditable method.
  • The closeCell method is called again from within the editCell method but returns early because the _editContainer field is null.
  • The timeout anonymous method from the focusout event handler is called, but the _toggleToolbarEditingItemsVisibility method is not called because _editContainer is null.

Stack trace:

n (kendo.all.min.js:9)
_destroyEditable (kendo.all.min.js:9)
closeCell (kendo.all.min.js:9)
tap (kendo.all.min.js:9)

 My recurrence rule is: FREQ=MONTHLY;COUNT=2;INTERVAL=1;BYSETPOS=2;BYDAY=WE;WKST=SU. This event falls on the second Wednesday of the month for two months in a row. When I edit the event, the wrong option is picked. Note in the screenshot attached we are on 11/09/2022 which is the second Wednesday. And the scheduler correctly shows this event. But the edit window sets the properties wrong. I am using a custom template for the edit window, however the recurrence editor portion is unmodified.

 I was able to fix this in the Kendo.all.js file directly. The highlighted lines below were added. When I publish this for customers I use the Kendo custom download tool to get a minified script of only what I need. I then need to carefully port this change using Notepad++. This makes it tough to update versions which is why I am a few versions back.

Bug report

When there is a DOM element with "page-break" class inside an element that is about to be exported to PDF, this "page-break" results in a new page in the reported PDF file.

If we hide the parent element in which the element with a "page-break" class is nested and export the content to PDF, in the result file, the content of the hidden DIV is not displayed but there are blank pages for each "page-break" class that can be found in the hidden element.

Reproduction of the problem

  1. Open this Dojo and run it
  2. Press the "Hide the DIV element in red" button
  3. Press the "Export to PDF button" and open the exported file

Current behavior

There are two blank pages at the beginning of the exported document. Each of these pages is a result of the "page-break" CSS classes inside the "#test" element

Expected/desired behavior

The "page-break" class should not result in the exported file if it is nested in a hidden element. Here is a Dojo demonstrating the correct behavior: https://dojo.telerik.com/iZAXiZEz

Dojo example.

  1. Click the "export" button

Current behavior

Drawing does not export the content. This is due to the img tags having a loading="lazy" attribute.

The images are exported. The attribute should be stripped if needed.

Bug report

When using the raw JavaScript files from the src\src\dist\raw-js folder (included directly via <script> tags), the Kendo UI version (kendo.version) always returns 0.0.0, and the package metadata in kendo.all.js has the version field hardcoded to 0.0.0.

Reproduction of the problem

1. Download Kendo UI for jQuery commercial distribution.
2. Use the files from the following path:
`src\src\dist\raw-js\`

3. Include kendo.all.js (and other scripts) directly in an HTML page using <script> tags.
4. Include a valid license key using:

`KendoLicensing.setScriptKey("your-license-key");`
5. Run the application and inspect the console.

Call: console.log(kendo.version);

Result: The version displayed is "0.0.0".

 

Current behavior

kendo.version returns "0.0.0".

_parsedPackageMetadata in kendo.all.js shows:

version: '0.0.0'


Expected/desired behavior

The kendo.version property should correctly reflect the actual build version (2025.3.1002 in this case).

The PACKAGE_METADATA placeholder should be replaced during the build or distribution process, even in the raw-js folder outputs.

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.

Currenlty, styles/font-icons/index.css has this line at the bottom:

/*# sourceMappingURL=index.css.map */

But the map file is not part of the distribution files, so it's causing the browser to throw an additional request for the map file.

Currenlty, the index.css.map is present in the node_modules/@progress/kendo-font-icons/dist/index.css :

But is not part of the Kendo jQuery distribution.

Expected/desired behavior

The distribution should be revised and the map file should be copied.
