Check the "foo" node. The change event fires for every checked node. It would be better if it fires a single time after all nodes have been checked.

Dear Telerik team.

I would love to have the possibility to use drag & drop with different browser windows. As shown here.

That way my customers could make use of their multi-monitor workplaces. Opening a grid or listview with items on one screen and opening a scheduler on the other screen. Then dragging from the grid to the scheduler.

Kind regards

Bernd

On line 157 of kendo.aspnetmvc.js:

return 'datetime\'' + kendo.format('{0:yyyy-MM-ddTHH-mm-ss}', value) + '\'';

As far as I know this format is non compliant with any standard format.
Could this please be compliant with ISO-8601 standard so that its more universal for APIs to be able to handle?

Dojo example.

1. Resize the browser window so that its height is smaller than the DropDownTree's popup height.
2. Click the DropDownTree to open its popup.
3. The popup opens and then auto-closes

The controller is returning the HtmlEncoded contents of a text file that the server reads in from the local operating system on the server, and I would like to display that information in a window or editor such that there is a left hand 'gutter' displaying line numbers and the file content has vertical and horizontal scroll bars.  The line numbers would scroll-y with the content, but should be fixed with respect to scroll-x.

A good example would be

 - the code panel in the Sources tab in Chrome developer tools, or
 - http://jspro.brothercake.com/code-examples/principle5.html, or
 - http://alan.blog-city.com/jquerylinedtextarea.htm (not my first choice though)

This dojo demonstrates a close solution I made using Window.

https://dojo.telerik.com/@RichardAD/IJuLeyOv

The 'gutter' is not locked (or fixed) though.  After many iterations I though of the Editor component and how it might already have line numbers built into it, and I could use it in a read-only manner to display the text file contents with line-numbers.

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. https://dojo.telerik.com/EwAsaKAf/3

I also posted a forum message here: https://www.telerik.com/forums/expand-collapse-arrow-fails-to-appear-if-a-class-matching-a-certain-pattern-appears-anywhere-in-the-header   

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

Bug report
Currently, DataSource bound Spreadsheet throws "Unsupported for multiple ranges" error when attempting to delete the content from multiple not adjusted cells.

The error is thrown by the values() method:

values: function (values) {
    if (this._ref instanceof UnionRef) {
        throw new Error('Unsupported for multiple ranges.');
    }
    if (this._ref === kendo.spreadsheet.NULLREF) {
....
Reproduction of the problem
Go to the DataSource Binding demo;
Select a few cells using the Ctrl + click;
Press Delete button on the keyboard;
"Unsupported for multiple ranges" error will be thrown from the values() method;

This bug has not been resolved in Version 2018.3.911. 

it's looks nice if we have an option to move chatbot image to either on first or last of message for multiple messages (currently the chatbot image located on the last message)

In some specific cases, it is required to show a bubble within a bubble in the Bubble chart. This is required to demonstrate some specific property within the bubble.
e.g.
The bubble position shows which project.
The bubble size demonstrates projects size with respect to the program.
The bubble within the bubble shows the current progress of the project.

When using a grid against a large table with server side filtering (ToDataSourceResult)

ToDataSourceResult builds a SQL query that converts the search string to UPPER() and therefore prevents the database from using its indexes. As SQL comparison is case insensitive that LOWER() is unnecessary.  

As we have may grids where this is an issue it would be time consuming to build out manual filters for each grid instead of using ToDataSourceResult

This was discussed here and there was no solution at the time:

https://www.telerik.com/forums/grid-filtering-on-text-using-lower-in-sql

I would liek to request an option to tell ToDataSourceResult() not to use LOWER() in the sql?

kendo MediaPlayer should allow set playback rate, allow user increase/decrease playback rate.

Currently the media player only supports YouTube and local media files. In think it would benefit from supporting other media providers such as Vimeo and Metacafe.

I would like the additional barcode added.

https://en.wikipedia.org/wiki/Data_Matrix

A Data Matrix is a two-dimensional barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern, also known as a matrix.

Currently min and max on DateTimePicker does not restrict time ranges. It only restricts min datetime and max datetime. 
Not time range within each date.

We need possibilty to set min time and max time to select like time picker has.

I would love it if I could add a header to the PDF when using drawTabularData. I'd like to add some header information (e.g. some text above the table) describing what the PDF contains. Ideally this would repeat on each page of the PDF.

For context, I'm using drawTabularData to export data from a Grid component to PDF in a way that supports horizontal page splitting (column splitting).

If the drawTabularData function could support grouping, that would be great. Right now, when I group a Grid by a column and then use drawTabularData to export the Grid data to a PDF, the table in the PDF is blank -- it has the right number of columns, but the rows are empty. I'd really appreciate it if this worked, so that users could have the full ability to export a PDF of the data exactly as it looks in the Grid.
