The TreeMap widget does not correctly handle items with null values. See this sample code: http://dojo.telerik.com/@jmpg/IxEHub

It's possible to filter the DataSource to not have items with null values, but it would be much better if the TreeMap widget would simply ignore items with null or undefined values.

i tried your demo example :"http://dojo.telerik.com/" its works as well on Firefox 56.0 but does not work on IE11 nor on EDGE as planified.
the videos are concatened in the same web page instead to appear in the specidied frame.
please correct and  tell me the solution on my mail below.

We want the file upload control (chunk save method) to save the state while navigating between different pages sharing the same master page

Hi,

it would be nice if we can have a distinction between days when using a timelineWeek or timelineWorkWeek.

If you have a lot of ressources (with vertical grouping for example)  it could be difficult to see when a day is ending and the other is starting: see here.

It could be nice if we can have a border with a different css class (ie black color) that shows this behavior.

We did it on our side by using the slotTemplate but it's a kind of workaround that adds extra code/rendering time that could be done by the component itself on the first place.

Developers should be able to specify grid column sort config property which is different from column field property.For instance, when listing products, my view model may have CategoryName property mapped from EF entity navigation property Category.Name using AutoMapper, while my sorting will use "Category.Name" on the server side.Example config could be like: 
columns[{title:"Category",field:"CategoryName",sort:"Category.Name"}]

This will allow me to flatten my view model without loosing sorting functionality.

Using kendo UI file upload feature, currently we can upload or remove the files. I wanted to view the uploaded file (and download the uploaded file)

I am trying to find why some Kendo UI controls do not work, and do nothing at all.  No error, just flat do not work and don't give any clue about why not.  Was told about this extension for chrome?  great.  Installed and... ?  now what?  there is a Kendo icon in the upper right, ok let me click that.  it opens the "store" to get extensions of all sorts and types and says the kendo inspector tool IS installed.  ok, and..? if I look at page source?  nothing different.  How this tool is used is not obvious.  So put instructions of how to use it somewhere?

Hi, Is there any control for image edit in kendo mobile ui, i mean after capture call image edit tool to edit image with few basic features like crop, brightness,rotate.

It's convenient for users who use older version of Kendo UI

I would like to see a startup seed that would work for the following requirements: 
visual studio 2015
Microsoft.NETCore
Angular 2
Webpack
Kendo 

how can we add minor grid lines between majorgridlines ??

After export there are html tags in cells of excel file. It could be fixed with custom handler for excelExport event, but it's not a good approach. Here is an example of this bug: http://dojo.telerik.com/eKARU/3

ButtonGroup is a part of Mobile Ui but on mobile it is not being responsive. Especially on small screen in portrait mode it is not responsible at all

The behavior of DropDownList, ColorPickers and probably more controls changes when a tooltip is added to them. When the tooltip opens, the ".k-state-border-down" CSS-class is added to the (e.g. DropDown) container. However, in the context of the DropDown, this class means that the DropDown is opened and therefore, the styling changes accordingly.

The following two DOJOs demonstrate this bug:

• Here, a DropDown without a tooltip works correctly: https://dojo.telerik.com/AvAxuQaK
• Here, a DropDown with a tooltip displays an unwanted shadow below the control: https://dojo.telerik.com/OGAVEzUb

We currently experience this behavior in the Editor widget when adding tooltips to tools that render the aforementioned controls.

kendo.ui.notification is not responsive which makes it difficult to use out-of-the-box in a mobile environment. See 
https://github.com/telerik/kendo-ui-core/issues/2351

But ideally in a kendo.mobile.Application, the notification should expand downward below the layout header or upward above the layout footer on the full width of the device screen.

I am responsible for creating Coded UI tests using Visual Studio 2013 against a web based application using Telerik KendoUI. When running my test Whenever I click on a specific drop down, and select an item the web application becomes busy as if it is trying to populated results to a grid. It never does. However, doing this manually (not running my test), the results are displayed. Now my tests were using Visual Studio record/playback mechanism through the UIMaps editor. Then I tried to create customized code to interact with the Telerik KendoUI control...it did not work. 

I have been reading that Visual Studio Coded UI does not support Telerik KendoUI controls.  I also read it does.  Apparently there is a Q1 2013 (v. 2013.1.0220) support package that will help in this. See link: http://www.telerik.com/forums/radtabcontrol-control-support-microsoft-coded-ui-automation

I am not sure where this package is or where to go get support for Telerik KendoUI. Does Visual Studio Coded UI support KendoUI controls? If so, where do I go to get support?  Or how do I add the extension and update to Visual Studio 2013 Coded UI?  What should I do?

I have a scenario where the form has enough elements to have performance issue with the validator, so I would like to be able to pass a selector to validateInput() that targets multiple inputs. 

Example: validator.validateInput($("input[name^=itemLine]")
