Rotator component.

We've used RadRotator component for asp.net ajax. Now we are doing this page on KendoUI jquery. I've not found how to change this particular component.

We have isnull and isempty operators for string fields. But it is too much "technical" for standard users. It is hard to explain difference between null and empty. It is the same for most of user. It is just "no value". There is no difference in grid view. Youll see empty space. Empty string or null value, it desn't matter. 

There should be operator to filter nulls and empty strings with one filter item. Something like "With value" and "Without value". It implements merged operators "isnull or isempty".

Support has no doubt provided help to hundreds of people with thousands of issues but these problems and solutions are not available to search.  Ideally it would be possible to make the basic problem and solution available in a FAQ, cleansed of private information, so that it could be searched by people before contacting support. 

It would take some time to setup but it would make it easier to self-solve issues in many cases. 

This is a proposal to have the excelExport function allow an array of columns to be passed through to it. This will then allow additional (hidden) columns of the grid (that is also available in the datasource) be able to be exported.

Develop a kendo form component and make edit field easy arrangement,just like bootstrap 12 grids system.the "popup" edit mode of kendo grid is not friendly when it has a lot of fields.The kendoForm component may be consist of form toolbar,form content and form footer.

Hi Product team!

I would love to have similar heat map chart on Kendo, as swimlane guys have:

or

Thank you! otherwise you are doing great job.

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.

TreeMap MVC Demo doesn't show how the colors ranges are achieved.

It would be help to show how the color rangers are specified.

Some ListBox widget ideas and proposals:

See screenshot: https://lh6.googleusercontent.com/TAVZGw63BSVVT6Nh8hXbiHerZ3L0krBzboONI07PpFByROeqKPiFgrlaPnTMtIUZ94D8xRog=w1920-h960

1. Add two search fields, so it is possible to search within the left and right panes individually.
2. Add headers above the search fields. They can be configured via templates. Also add options for selecting/deselecting all items in the corresponding pane. Checkbox’s middle state should also be considered.
3. Add option (API) for enabling/disabling ListBox widget as a whole widget (similar to DropDownList, ComboBox, etc.), not only item by item.
4. Add support for data virtualization (similar to DropDownList, ComboBox and AutoComplete).
5. Add API (public methods or fields) for retrieving the current status of the items in the ListBox. For example:
- a method/property which returns the count of currently selected items
- a method/property which returns the count of currently showed items (if searching, not all items will be visible)
- a method/property which returns the count of total items
This information can be shown in the headers via template, for example.

The listview endless scrolling is a neat feature but it will be good if we could configure it to be in reverse. We are building chat system in our app and want to have the endless scrolling widget but need it to scroll in reverse.

Add columns to timepicker to have multiple columns instead of a long list.
Like you have for the Telerik Ajax Timepicker 

It would be great to be able to sort the legends of a chart, without changing stack order.

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?

Starting with Kendo-UI 2017, I've noticed that the row filter now shows two "x" buttons to clear the filter (one inside the text box and one to the right of the text box).  It's confusing having two of the exact same buttons next to each other, each doing a slightly different thing.  Please add option to remove either one of the two buttons without having to either do a dataBound or CSS trickery to hide them.

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.

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.

The interface for PromptOptions does not extend DialogOptions like it should. I added it into my definition file, and it compiles and works fine when testing.

    interface PromptOptions extends DialogOptions {
        name?: string;
        messages?: PromptMessages;
    }

R2 2017 release finally add a new KendoListBox component.

However, It lack some features, available in dropdownlist, like filter and item grouping who prevent me to use it for huge item list.

..,or make it at least optional when using grouped column headers. Scenarios with many or repeating column titles would extremely benefit from this. 

A status-specific control would support max, min, targets, warning levels, etc and not be bound only to percentages as I see in the screenshots of http://www.telerik.com/support/demos or in the other dashboard sample. 
An example of this is:
