Add a new control to edit filters/queries like in Visual Studio online (see "How to: Design a Query by Using the Query Designer", https://msdn.microsoft.com/en-us/library/ff852016.aspx)

Data aggregation is not always desired with date data.  Scatter plots do not work well with dates.  I want to map every point of data I have without having them aggregated in different BaseUnitSteps.

I'd like an option to turn off data aggregation for date series.

Work like à tree view, but display as an organisation chart to see a company hierachy

The kendo.drawing.TooltipOptions do not provide a 

show { duration: [time]} 

option that will allow showing the tooltip for a certain duration of time, after which the tooltip will disappear automatically.

Can this be added?

Splitter bar - animation when collapsing and expanding 
Would enhance a more graceful splitter widgets actions  

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

It would be nice to apply known Excel formatting options to our export cells. For instance, we'd like to be able to rotate a cells content 90 degrees, which Excel allows, but we aren't allowed to add that custom formatting because Kendo's export doesn't handle it.

I am trying to use the DropDownList and find this level of documentation:

 <div class="demo-section k-content">
    <h4>Products</h4>
    @(Html.Kendo().DropDownList()
          .Name("products")
          .DataTextField("ProductName")
          .DataValueField("ProductID")
          .DataSource(source => {
              source.Read(read =>
              {
                  read.Action("GetProducts", "Home");
              }); 
          })
          .HtmlAttributes(new { style = "width: 100%" })
    )
</div>

The only other source file is a simple Controller Action method to return a result. There is no indication of what type of data is to be returned by the read.Action("GetProducts", "Home"); 

What fields are required in the data?
What field or fields are passed back to the Controller on Submit?
Is it JSON?
Is it in a wrapper like the Grid uses?

It is issues like this that make ALL the Telerik products difficult to use, and makes me consider using other tools. I think it lowers the value of the tools when Telerik appear to be happy that documentation of this level exists and users have to find answers and working real life examples on sites such as StackOverflow.

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.

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

Hi Product team!

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

https://swimlane.github.io/ngx-charts/#/ngx-charts/heat-map
or
https://swimlane.github.io/ngx-charts/#/ngx-charts/calendar


Thank you! otherwise you are doing great job.

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".

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

The timezone should be adjustable [e.g. like in Moment Timezone date.tz('Asia/Tokyo')] or today should be accessible/configurable from outside the widget. Currently getToday() always returns the local time. Suggestion: Add the attribute today to the options and change the initialization of var today = new DATE() in getToday() to var today = new DATE(options.today) ...

Please support partial formatting of the output Excel cells

I keep paying for the kendo subscription and I keep seeing more platform support. That’s good for you to gain market share, but I’m not seeing anything substantially new. ASP.NET has way more features, how about migrating some of those items to Kendo UI?

It would help the user experience of entering times if the time picker had a styling option that would display a clock style interface where users can select the hour and then minutes.  This is similar to how time pickers work on mobile apps.

Indeed today, to correctly display red or other points depending on the template, it is necessary to make lines of codes so that the rendering is present.
It should be done automatically as soon as the array of dates changes (as it is linked to the calendar), I'm talking about the small calendar that is in the header of the scheduler.

Please add the multiple date selection option to the kendoDatePicker component as for the kendoCalendar.

It would be useful in the table column header to filter date values.
Currently, I have to use two DatePicker to select min and max date. Calandar is not an option in my case.

It would be very useful from a visual and functional perspective to be able to view scheduler items in a multi-year view, that seems to be currently unsupported.
