The "change" event on DropDownList is being triggered when the value change of the widget is via API and not triggered by user interaction.

Steps to reproduce:

  1. Manually select a value for category (like Category 4); a console item should be written for user change
  2. Click the "change doc to empty" button which clears the category
  3. Click the "change doc to values" button which programmatically sets the category

Expected: a log item is NOT added because the change was programmatic and the log item is triggered on "change"
Actual: a log item is added even though the value change was programmatic

The change detection inside the select widget is faulty in that it seems to be effected by focus/blur state.

This issue was found after upgrading kendo UI.  I believe the issue was introduced in 2018.1.117

If I read I find “Setting Handlers through k-on Attribute” which suggests that I should be able to write `k-on-` prior to any of the events documented at and automatically run under `$apply()` or `$applyAsync()`. However, when I try that, my event handler doesn’t even run at all.

I think this is an oversight.

I can reproduce this in which is generated from the link at which uses AngularJS v1.7.2 and Kendo UI v2018.3.1017.

When using AngularJS binding for dropdownlist options in the latest version of Kendo (2018.3.1017), the option labels are not dynamically bound to the scope/controller.  I changed one of the options to have the label {{::foo}} and set the field foo to "BAR" when initializing the scope.  When I run this code with the latest version, the literal text "{{::foo}}" is displayed for the first item of the drop down.  When I use an older version of Kendo (2018.2.516), the text "BAR" is displayed for that item.  This is a regression bug that is causing an error in our product.

Here is a testcase that illustrates the problem.  To toggle between the working and broken versions, change the CDN values.

Dear Support Team,

Please try the following scenario. Create a weekly recurring event for the 4rth of April that has no end. 
Go at the next week (9/4 - 13/4) and move the event (11/4) 1 hour forward. At the confirmation popup please select 'Edit the series'.
Go back to the previous week (2/4 - 6/4). The event of 4/4 has disappeared!!

The specific dates are used as an example. Feel free to use any date your want.

Thank you in advance,

When you place a <label> inside the template of a panelbar, and click on that label, the select event fires twice instead of the expected once.

Note: works as expected on collapsible items, only items without children exhibit the problem.

Reproduction of the problem

Expected/desired behavior
the event keeps firing only once as if you clicked on any place in the item outside of the label.

Potential workaround:

Unable to edit date properly, when date is selected from the Kendo UI date picker.

Provided below is the dojo for checking


Don't have issue in older versions in  Kendo UI 2017 R1 and lower versions,

found the issue from the version Kendo UI 2017 R2 and above

Hello Support Team,

with jQuery 3.3.1 the resizable option set to true is not working with the configuration in the example below. When removing other options like "toolbar" or "scrollable" it works. :D 

See the following example:

With jQuery 1.x everything works fine.

The autofix column feature does not work properly if you enable sorting on the grid. You can see the issue if you open the Dojo for the following demo:

If you sort e.g. by column "Ship Country" and sort ascending you will see the name of the column ending with "..." but not the icon for the sort direction. If you press the column again and sort descending than everything works as expected - the column width increases and the icon is show.

I tested the problem in multiple browsers, but the main browser I have to support will be the IE.

The following event-handler does not work when run in a mobile environment (iPad). Otherwise it works as expected:

Result: all columns a set to their minimum width.


    var grid = $("#grid").kendoGrid({
        dataSource: dataSource,
        columns: [

// ...       

        columnShow: function (event) {

            for (var i = 0; i < this.columns.length; i++) {

                var col = this.columns[i];
      // ...
        filterable: true,
        sortable: {
            mode: "multiple",
            allowUnsort: true
        pageable: true,
        reorderable: true,
        scrollable: true,
        columnMenu: true,
        mobile: true,

In my kendo grid , when i apply a filter to 2 columns, first i apply filter to numeric column which results in no value and then after that i applies the filter to a string column combined with numeric column which also results to no value, Nothing is displayed. But when i remove the value from textbox of numeric column and enter filter, no data being displayed as string column filter is there but in case i remove the value from textbox of string column and enter filter , numeric column filter also got removed.

I also checked the kendo functionality , but not getting any solution for this problem.

Link to GitHub issue -

### Reproduction of the problem:

1. Run this dojo
2. Collapse one or more of the subCategory groups
3. Collapse the category Group
4. Expand Category

### Current behavior

The aggregate rows are missing and the locked and unlocked content is misaligned

### Expected/desired behavior

Rows should be aligned

1. Open "Sample Kendo UI SpreadSheet Example.html" attached html file in the chrome browser.

2. Click on open button in the Toolbar of the spreadsheet.

3. Select "Sample Excel with Font Colors.xlsx" attached excel file. This excel file contains headers with background color and Rows with ForeColors.

4. Now when the file is loaded, you will observe that B2, B3 and B5 should come up in Red fore color but the fore color of these cell in the kendo spread sheet is Black.

5. Similarly C2 to C5 should come in Green color but the fore color in the spreadsheet is black.


Query: Kindly let me know how can we achieve the fore color present in the excel sheet show show up in the Kendo UI Spreadsheet?

Bug in js\spreadsheet\numformat.js makeDateFormat


You appear to be using the wrong indices inside a nested loop.

if (/^(?:date|time|ampm)$/.test(section.body[i].type)) {

Should be (switch i to j)

if (/^(?:date|time|ampm)$/.test(section.body[j].type)) {

This is an error that took us an hour to figure out.

We are using the right-arrow icon as part of the content within a collapsible header to represent a state transition. (See image)

We found that the expand/collapse icon did not appear.


Further investigation reveals that if the header content contains a span with a class matching the regular expression k-i-arrow.* then the expand/collapse icon doesn't work. It could contain anything else, it was just that one class pattern that threw it.

See this example.

I also posted a forum message here:   

This is clearly a bug, and one that I suspect can be fixed easily.

When user inputs text that does not match any of the items in the data source and presses the down arrow key, the "suggestions" drop down list opens up with an empty list when the configuration option is: 'noDataTemplate: false'.


This seems to be a regression since it appears to be working in an older version:


Demo for suggested fix:

Note the kendo version (2016.3.914).


Same demo with newer version of kendo (2018.2.620):


Reproduction steps:

1. Type a string in the AutoComplete that does not match any values in the data source, e.g. ("123")

2. Press the "down" arrow key to open up the suggestions dropdown.

The suggestions dropdown opens up with no items -- it should not be opening up at all.


Behavior in (2016.3.914) is that the dropdown does not open when using the arrow keys if the typed in text does not match any of the items in the suggestions list. [Correct]

Behavior in (2018.2.620) is that the dropdown does open with an empty list when using the arrow keys if the typed-in text does not match any of the items in the suggestions list. [Incorrect]
