Having the ability to do "in-line edits" can sometimes be helpful.  Here is a link to a jquery plugin I use often. Perhaps this would be something useful for Kendo.

What i think of it is converting checkboxes list into more friendlu UI element. For example we have list of checkboxes with the same name but different key

Name="checkname[1]"

and so on. So i set something like

$(".checkbox[name=Checkname]").kendoCeckboxes()

Then kendo convert it in to togle buttons. You can set how namy columns for example. And it will convert to something like table with every cell as toggle button and selected options are highlighted. Of course you do not use table html elemnt i just describe idea.

This will be more friendly as on desktops as on tablets. 

The Book control is great in Silverlight. It may be possible to create a similar control in Kendo

When working with AJAX it's essential to be able to validate a form on the fly, return errors, and deal with them without needing to actually submit the form. Please make sure the validation library works as a callable method rather than just a form submit event binding.

I've experimented with the Kendo UI on my iPad, with the VoiceOver feature enabled and some of the widgets work well, but not all do.
Adding support for VoiceOver would add a huge level of accessibility to our apps.

The forum is great but missing some critical features.

- Search a specific Topic area "Kendo UI Framework" or forum like "Data Source"
- Active Threads (show threads updated to today or since last visit)
- More notification options

A Calendar control for Kendo UI Mobile would be awesome.

Seems like lots of Chart features are yet to be implemented.  I want to use jQuery to hack positioning of elements like axis titles and replacing some rendered paths with images, but without classes the selections would be expensive and maybe imprecise.

This will help take some of the heat off Telerik while users wait for more functionality in the next release. Let us modify what we need!

In some specific cases, it is required to show a bubble within a bubble in the Bubble chart. This is required to demonstrate some specific property within the bubble.
e.g.
The bubble position shows which project.
The bubble size demonstrates projects size with respect to the program.
The bubble within the bubble shows the current progress of the project.

The ability to show confidence intervals (80% and 95% intervals). Something like what can be done with the Percentiles plugin for Flotcharts:

Navigator works great.  Pan and Zoom work great.  But when you try both on the page zooming and panning completely mess up the data navigator.

I realize pan and zoom are new so maybe this is already in the works.

My support ticket pointing out the problem:
  http://www.telerik.com/account/support-tickets/view-ticket?threadid=1013202

should have a basic component for split button

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. 

Like jQuery 2.0, a version that leaves behind the older Internet Explorer 6, 7, and 8 browsers. In return it is smaller, faster, and can be used in JavaScript environments where the code needed for old-IE compatibility often causes problems of its own

Let's be clear, i know there is notification. But, i think that we can add some functionalities to this feature.

It will be great to have a notification center:
-It display the number of notification
- When we click on it, it will display the notification stack

A little bit like Facebook when you see the notifications.

The horizontal data selection for line charts works great...for the applications I need to build, I also need the same sort of selection vertically. Please consider implementing this soon...i know others have inquired about this as well.

If you have multiple axes shown on a chart it can be hard to determine which axis relates to a particular data point. 

Currently you can use color to visually tie them together (see http://demos.kendoui.com/dataviz/bar-charts/multiple-axes.html) but this isn't a great solution.

What would be nice is an option to highlight the appropriate axis when you hover over a data series point (similar to the new feature where data series is highlighted when you hover over the legend)

Hi, 
In kendo Line chart, currently the plot area can be colored using plotBands. 
In line with that is the requirement to color different ranges with different colors in the y-Axis line alone.
The line size can be made to 3 or 5 px to shown the color clearly.
This will help the user 
1. to understand the criticality of the different ranges.
2. Mostly line charts will be shown shown in reports, and will be given as printouts to the patients (in case of hospitals),  a report will have multiple line charts components, providing this feature will help the customers to reduce the cost on printer color catridges (that will be used when printing the whole plotbands for different ranges).

Thanks.

The grid and chart can be used in mobile apps and seem to work properly.  (See http://kendoui-feedback.telerik.com/forums/127393-telerik-kendo-ui-feedback/suggestions/4522456-touch-grid-for-tablets-that-has-as-many-features-a for the suggestion that they do work).

However, they don't adapt to the mobile appearance like the dedicated mobile widgets, which makes them hard to use in cross-platform mobile applications.
