we need the polymer js which is used in Kendo UI
like Angular js we need to use Polymer also

Add support for cell.formula on Woorbook

Having a character counter for textbox & textareas gives users nice little heads up as they start typing to summarize the text for a fixed length. Not sure about internet applications but its becoming more & more a requirement in business applications. Please give it a thought.

the only way to style only the mulitselect dropdown list differently than other dropdown lists is to run a js script to add a css class...

  function setupMultiSelectULStyle (styleName) {
    var selects = $("select");
    $.each(selects, function(index, item) {
      var data = $(item).data("kendoMultiSelect");
      if (data !== undefined && data !== null)
        setupMultiSelectULStyleSingle(data, styleName);
    });
  }

i think if you are creating elements that are not wrapped in parent element style they should have some way to style by parent control type differentiated css selector


<div class="k-list-multiselect k-list-container k-popup ... " id="..." >
<div class="k-list-dropdown  k-list-container k-popup ... " id="..." >

The library is getting pretty big - lots of great features, but still big.  I would love to see the team take some time and offer more options to reduce the size of the ALL and CUSTOM builds.  Perhaps look to drop old browser support and do a pass on tightening things up.  Set a goal for the team to reduce the library size by 10%.

Currently the calling .hide() on a Kendo UI Notification hides all of the instances of that notification. It would be useful to have support for hiding a specific instance, perhaps by 'ID'.

I've accomplished this by using the .getNotifications() method and iterating over the notifications to find the one I wish to close, however built in support would be a timesaver!

There are times when it is not obvious that the Listview contains more records than are displayed. It would be nice to have an optional indicator that there are more records above or below the current scrolled view. Another option is to keep the scrollbar turned on.

After I filtered a column and deletes the filter content and press again the "Filter"-Button, nothing happens. Filter with empty string should clear the filter on the column,

I have a very simple chart, with date category axis, 2 series with just 2 values (two days). I set rotation for labels on a category axis to 45.
When any "label" in a legend is clicked, the labels disappear.
This problem appears only if rotation is set to 45. I have tried to set rotation to 40 or 90 - both are just fine. But rotation 45 seems to be broken.

We recently implemented a bubble chart for our system. The users loved it but wanted to see custom markers that would indicate "direction" of the data value. We couldn't see a way to put custom markers on the bubble chart (hence the term bubble I guess) so we looked at the scatter chart. This did everything we needed (custom marker, relative sizes, etc) but did not allow us to click on a marker that was behind another (like the bubble chart). We would like one or the other.

On RadMap and other visual tools, it would be beneficial to have the ability to alter colors for specific data points or have each data point have the ability to define a color.  This would be similar to how series in RadCharts work in that I could define a color for a specific marker, or layer, etc.

It would be beneficial to add additional support for tooltips natively on the Bubble Layer in RadMap

It's great having the tsd files as part of the full download.
It would even be better if you could submit a pull request to the DefinitelyTyped github repo https://github.com/borisyankov/DefinitelyTyped , as that would allow us to integrate Kendo UI documentation in JavaScript projects out of the box.

This repo is used by the npm tool "tsd", which allows for really easy automation of the downloading and updating of tsd files.

This would be akin to the bower dependency that you already submitted for kendo.core.

Automatically add page breaks to PDF export, currently if exporting contents with very long contents it exports as one single long page, the page break should happen based on the Page size for example "A4"

Our users love how pretty Kendo UI charts are. We usually visualize data for them with Pie or Bar charts, often in combination with a Kendo UI Grid.
However they almost always want the ability to export what they see in the browser to PowerPoint. One workaround might be to save the Kendo elements to an image and stick that into a PowerPoint slide. However they don't want that. They want a real PowerPoint slides with real PowerPoint charts and grids live objects like they were initially created in PowerPoint. We have managed to implement something to do that with OpenXML, but it will be a HUGE time saver if Kendo does that out of the box.

It would be useful to have border configuration as an option when using kendo.ooxml.Workbook to create an excel file (i.e. sheets.rows.cells.border)

make a widget like the asp.net Details View control. 
This displays the details of a single row from a grid in 2 columns. The Left Hand column has the field labels, the RH column has the values. 

Wondering why there still no feature request open about this, but here we go.

Add RTL support for mobile widgets. RTL it currently supported throughout Kendo UI Web, but not in Kendo Mobile.
Mobile Drawer should slide from the right, Mobile ListView currently has issues etc.

[  Numeric Text Box ] [  /\  ] [ \/ ]

the spinners are small and I would like them to be bigger at the cost of screen space

We have a use case where we are using ContextMenu with the following configuration:
showOn 'click'
alignToAnchor  true, 

Anchor being a button and on click of the button, context menu opens but the focus doesn't shift to it and remains still with the button.
