Other vendors offer visual representations and better access to what controls are available and how to quickly use them in different scenarios. I cannot find any visual such as http://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html?component=home&demo=all which nicely highlights what each control looks like from an index perspective.
Furthermore, the code in a cookbook should be copy and paste and not have dependencies on hidden helper classes.

Kendo UI pivotgrid should have a way to customize the filters.  Specifically have a date picker for date fields and a date range.  But something so we can override what the default is.

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.

The option in the Kendo Spreadsheet to show the unmarked values when a filter is applied instead to reset it by pressing the Clear button

It would bei nice if the gantt would support Auto Height like Grid is doing and is only rendering the Height for the used elements, when you define no addiotional height property.

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

Since aggregation causes data to change when using a date axis (new minimums and maximums), provide a way to retrieve the new minimums and maximums for each series plotted on a graph.

Spreadsheet does not have a configuration option for maintaining the scroll position per sheet when scrolling horizontally. Currently spreadsheet maintains the common scrolling position whenever we move different sheets.

It would be nice if you could add a Legend to gauge control with multiple pointers, so it can be easier for users to determine which pointer stands for what. Something like the Legend control on RadHtlmChart, that allows for series to be toggled, except in this case it's the pointers that will need to be toggled.

All controls which work with Models (validation/grid etc) should recognize displayName instead of field name to allow localization.

Model.define({
     fields: {
              Description: { type: "string", displayName: "Beschreibung", validation: { required: true, maxlength: 200 } },
              Number: { type: "number", validation: { min: 0, max: 300 } }
     }
   });

Kendo map wraparound feature for geojson type

The wraparound feature in Kendo map doesnt work for GeoJso type, can we have this feature added.

Please consider to support grouped boxplot for Kendo UI. For example, we would like to compare the machine capacity within multiple parameters, like machine type, machine no, and employee. We need to group 2 or more parameters in x-axis. Many statistical package could generate this group boxplot and reach our request. But we need to developt a web application with this function.

The idea is to have demos of the different widgets made with Typescript. Nothing fancy just the simple demos so we can understand the different ways to create the objects and their interactions.

Having this ability would be very useful, as the current solution from an angular standpoint is targeting the listviews before state using CSS:

   [kendo-list-view]:empty:before {
        content: '{{$ctrl.noResultsCaption}}';
        display: block;
        text-align: center;
        padding-top: 5px;
    }

ToolBar items only have two states (besides visible and enabled):
- displayed in the toolbar
- displayed in the overflow dropdown (kind of responsive because not very practical on mobile devices where you are left with two visible buttons at the most, and a possibly large overflow dropdown)

On mobile devices, we would buttons buttons that shrink to icon only (no text) before being sent to overflow dropdown. This would improve greatly the responsiveness.

Package kendo ui widgets as ES6 modules

Kendo's support for conditional number formatting results in it picking the negative or positive format even when the underlying value is being rounded to zero. This is generally not what users expect and is inconsistent with .NET's number formatting.

Here's an example:

kendo.toString(-0.1, "0;(0)") // results in "(0)" instead of the expected "0"

In contrast, .NET behaves differently:

(-.1).ToString("0;(0)") // results in "0"


It would be great if kendo's toString implementation incorporated this logic.

More information and examples are available in this Kendo forum post:

Currently grid popup using window. It will be better and nice if grid use dialog as popup screen

Locked columns can only be on one side of the Grid.
In Kendo Grid, is it possible to have locked columns on the left and right side.
For Eg: my grid has like 20 columns and i want to lock first few columns to the left side and also lock the custom commands column on the right side of the grid.

Ability to show a circle on a map to encompass a specified number of miles/km from a point.  This is different from the Bubble layer as it will keep the radius in miles/km when zooming in/out
