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

When using aggregates, it should be possible to define your own aggregate function, or even set it globally for kendo, so it could be used in other places. i.e. 

currently you can only specify the function name like 'sum', 'avg', etc. with this idea you could give the whole function like function(arguments...) {}

Also from what I saw it would be nice to have the `functions` object from accessible, so you could add your custom functions, like:
`['median'] = function(arguments...) {}`

Kendo UI supports PDF export. It would be great if you could add glyph mirroring support to it as well ( PDF export of RTL languages such as Arabic and Persian need this trick to work properly.

It would be nice to have a built in PDF viewer control in the Kendo UI and Kendo UI Mobile. Especially Mobile so we do not have to search the net for decent controls that may or may not work for the different devices.

Adding the same functionality as filterable.extra but in row mode. Similar to the following demo
Last Updated: 10 Jan 2019 19:08 by binki

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.

The Kendo UI Window features in many widgets as an editable popup and form container - like the Kendo UI Grid and TreeList, the Kendo UI Diagram and it would be great to be able to keep using it and open it elsewhere dynamically as right now this takes no effect.:


Thank you for voting!

Currently events >24h are automatically shown in the all day area. This is confusing if the event starts or ends somewhere during the day. E.g. it starts at 5 p.m. on tuesday and ends on 11 a.m. on thursday.

Noone knows when the resource is really available if the event is shown as all day from tuesday to thursday.

There should be an option to turn that behaviour off and show such events as regular events.

Maybe the only thing needing change is this line in _renderEvents:
var isMultiDayEvent = event.isAllDay || event.end.getTime() - event.start.getTime() >= MS_PER_DAY;

It would be nice if the diagram control could support complex shape json export ( and import (diagram.load()), like shapes contains TextBlocks, etc.

It takes lot of time for rending thousands of records from client side, some times browse gets crashed, causes performance issue. Virtualization support will help us to overcome this issue, as the same provided in Angular 1.x and Kendo MVC controls. Can you please provide virtualization support for Autocomplete & Multi Select controls.

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,

Telerik Upload is lacking image preview and scaling options. Please add support to show a thumbnail of images before uploading and also the ability to resize images on the client. This is really important when you have people wanting to upload photos and they select big files when you only need a small image. Images can be scaled server side but much faster upload and more convenient client side.

Examples of free components that already do this:

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:

I would like to be able to do conditional formatting against other columns and not just the existing conditional formatting.

For example:

Column 1 = 1.2
Column 2 = 1.5

If the value of Column 2 is greater than the value of Column 1, I want the color to be green.
If the value of Column 2 is less than the value of Column 1, I want the color to be red.
If the value of Column 2 is equal to the value of Column 1, I want the color to be black.

We are using Fusion software and the grid ARIA attributes of rows are "aria-describedby". This results in the invalid/wrong action tips for Fusion users. If we change it to "aria-labelledby" it works well. 

Currently, we have to override the private method _tmpl so we can edit the hardcoded attribute. We need to be able to change this part of the source:

if (navigatable) {
    rowTemplate += " aria-describedby='" + + "'";

It would be great if we can configure them from the grid settings.

 ariaAttribute: "aria-describedby"

Then the _tmpl function will change like this:

if (navigatable) {
  rowTemplate += (that.ariaAttribute ? that.ariaAttribute + "='" : " aria-describedby='") + + "'";

Thank you in advance.

The NumericTextBox should behave like standard input fields and automatically select all the text when tabbing into the control. This should work for NumericTextBox controls whether using inside or outside of a Kendo grid.
