I am seeing this bug for more than year ago, it would be really nice if you fix this issue, because it works really very well in Ignite UI, here is the jsfiddle.

http://jsfiddle.net/KendoDev/5Sssk/

Allow binding the grid to a dynamic model (dictionary) and use it in the inline editing mode.

This will allow us to decide which columns are shown and which editors to use from the server side. 

If we do this today, the data will not load.

Support row templates in conjunction with frozen / locked columns

A lot of app developers like the idea of adding a chat function to their app. In UI for WP Telerik has this beautiful Conversation View. Make the available as a full-blown widget für Kendo UI (mobile). Think of SignalR as a possible backend technology. Chat bubbles should have the ability to show text/pictures/emoticons. Provide a ready2use class for asynchronous or backgroud-sync (up/download) e.g. for ASP.NET Web API.

We need the ability to get the next occurrence of a recurring event given a start date. This has nothing to do with the scheduler widget but a function that can take a recurring event and start date and return the next occurrence instance (not all the occurrence). We need this to tell the user when they have their next appointment.

Pattern fills for Chart like this one http://www.amcharts.com/demos/map-with-patterns/?

Right now, the only charsets that are supported are UTF8 and ISO/IEC 8859-1.  

Since I have a lot of data to encode, I can get a more efficient output by directly writing a stream of bytes.

Modalviews have to be defined on the page at startup. It would be helpful if a modalview (and a view) could be returned or replaced as a MVC partial view, i.e. make it possible to create and open a modalview after the page has loaded.

Hide a column in a grid with a detail template

It would be great if there was a kendoUI atmosphere package library for Meteor js

Telerik is pushing their support for Angular pretty hard now, and I think that is wonderful. But with it, you're still leaving the documentation on the matter pretty sparse and kind of obscure.

Right now, it is kind of tucked away out of sight here: http://docs.telerik.com/kendo-ui/getting-started/introduction

Though to your credit, you __have__ updated all of the demos with an _Angular_ example, which is __very appreciated__ and I thank you much for it.

I think it would make me, and many others I know, a lot more comfortable if the support for Angular were treated a bit more first class. As long as it continues to be put in out of the way places, it still feels very 'unofficial' or 'tentative'. Could we possibly get a more expansive documentation right on the demos page, perhaps under "tools", or a new actual "Angular" folder on the primary API documentation?

When changing visibility of tabs within tabstrip, active tab may become invisible and tabstrip moves to a state when no tab is selected. I think it should be optional to set that I want it to go to the first tab available.

when the mobile view uses a header, containing a toolbar as header it would be nice to be able to have a view title like in the navbar.

Box Plot (Box and Whisker) works great but would like to have Vertical instead of horizontal.

In columns array if you set field attr with a number you'll get an error

It would be nice to have a widget to display network map of all connected node and links.

The kendo core would benefit from having integration packaging systems other than npm, especially jamjs. Kendo already implements AMD which is what jam specializes in.

If there has two or more gantt chart on the screen. some of the value should be able to move by dragging from one to another rather than defining again.

ListView selectable feature could be done better. One thing has been bothering me. Here's an example: http://demos.telerik.com/kendo-ui/listview/selection Go to the last page and try to select outside of list items. Problem is that it isn't possible. Maybe Telerik has thought that user also has to be able to select text normally. But for instance in Windows Explorer you can begin selection anywhere inside the window and I think the user expects that behavior.

Extend "filterable" to match the datasource's "filter" (singular, not "filters") configuration option.
