I want to display tooltip on category axis of chart on mouse hover event, instead of click event.

The ability to use multiple navigators on a column chart. 
Currently the option to compare two ranges of data on the same chart is not available out of the box.

Ability to quickly filter and select item from dropdownlist by typing the first few characters of possible dropdown options and having the matched item be the selected item. This is already a normal function of regular dropdowns, and would make keyboard manipulation much faster.

Kendo AutoComplete should support input type="number" so that OnScreen Keyboard appears on Numeric Screen when only want Numbers to be input (or at first). Currently it does not (as per support call) so normal alpha OSK appears first and User has to immediatley chnage to Numeric keys. (eg for numeric postcodes etc)

On data management controls (like the grid and the listview), if they are bound to an ajax remote data source and an error occures, it will silently ignore it and accept the changes. You listen to the error event on the data source to display the messages, but that wont stop it from accepting the changes. You can add a single occurrence listener on the grid's data binding event to prevent it, but you are starting to get into weird hacks. Then theres the listview, which is an even uglier hack.

Not only should this be standard behavior in the first place, but it's a pain to even get it to work with hacks.

Please change the behavior or at least add an option to prevent accepting bad data that didn't even get saved in the database.

Is integration with aerelia planned?

http://aurelia.io/

The toolbar has buttons and split buttons but no menu button.

A menu button is a button which triggers a popup button; in other words it is a splitbutton without the split. See http://getbootstrap.com/components/#btn-dropdowns-single

Easy to do and really useful!

Basically I'm asking for [`optionLabel` from `DropDownList`][1]. I can't do it using the datasource, because my data is remote.

please add touch support for tablets/phones to the scheduler and gantt widget, for moving events or tasks

I'd like to show Totals for Stacked Bar / Columns Charts.  Maybe this could be like Aggregates in Grid where the Aggregate is accessible via ClientTemplate?

You should option to convert UTC time from database to specific Timezone with DST checking in telerik Reports. The problem is as below: We are taking user date time from aplication UI in CST and converting in to UTC in C# and saving it to SQL and for displaying also we are Converting From UTC to CST with DST checking in C# and showing in to Razor view. Its working perfectly. We have stored application wise timezone settings in our SQL. But to display any datetime in Telerik Report we need to convert from UTC to CST with DST checking. Currently there is no option available to convert it in Report. To resolve this issue we need some feature in reports.

The radial and linear gauges currently DO NOT support a title and legend option. It forces me to customize the widget after it's rendered, which means that the look is inconsistent with the other Kendo widgets.
Please add support for title and legend for the gauges.

Similar to the Funnel chart, some chart libs also offer a Pyramid Chart. We are also interested in the Pyramid.

Add an option to rotate the text 90 degrees when the tabPosition is set to Left or Right.  Without this on a mobile device the control is useless as it takes up the whole screen.

Thank you for  adding Excel-like filter. This is what we wait for a long time.

What a revolutionary concept, I made it myself!

Ontario and Canadian Govt ask all new sites to be WCAG 2.0 level A compliant since Jan 2014 and AA compliant by 2021. We need toolset fixed for this regulatory requirement.

In the applications I work on we have multiple maps where there are shapes with different colors, tooltips with data, and various map markers. 

The Map widget would be greatly enhanced if it could support a legend!
