Make the Kendo UI Dojo embeddable via an iframe. Exactly what jsfiddle.net offers. 

http://doc.jsfiddle.net/use/embedding.html

When I save or return the value of a MaskedTextBox, it sends the value including the masked.

Mask: (000) 000-0000
User Enters: 3331112222
Value: (333) 111-2222
Expected Value: 3331112222

I think it should only send what the user entered and not include the mask. Right now I have to manually remove all of the mask characters from the value. It should only display the value with the mask, not store it.

Right now, Kendo's angular support is beautiful, but I found a majorly lacking feature. 

By default, you can bind to either the ng-model or k-ng-model to get the value from a widget. But there are a number of widgets that have a dataItem() function for returning the actual object stored.

This is extremely useful, and I use it a lot in everyday coding. While I can overload the change(e) function, it would be REALLY awesome if retrieving this and binding it back to the $scope was built in. I have a demo directive written to show you how I am accomplishing this right now, but it would sure be nice to have it baked right in.

Since the uservoice portal does not allow markdown or formatting syntax, I am linking you a pastebin so you can see the code I created.

This is certainly not bulletproof, but here is how I use it;

<select kendo-drop-down-list k-options="kendoDropDownListOptions" k-data-item="Model.Group"></select>

I sure would appreciate a more native approach, though. I don't enjoy having to go around Kendo's back to do this, when it really should be baked right in. The function is provided out of the box, there's no reason not to allow for it! This would easily be done by adding a bit of code to line 375 in kendo.angular.js, as an OUT3 case outcome. I have successfully gotten to the function in question in that part of kendo by using widget.element.data().dataItem(), but that is a pretty hacky way to do it. I'm sure that the actual devs could find a much smarter way to get to it.

Right now on a mobile device it will put just what it needs into the overflow box. I would like to see the ability to force everything into the overflow when it is activated at all.

Why not zoom on just an canvas - for example with a photo then a whole page or tab

In help text at:

Kendo Grid 'locked' help text needs link to 'Frozen Columns' - can't find any help.

It would be very helpful to have more events on every controls and better event arguments on existing and future ones. This include things like click events that could be listened with a standard event binder with proper selector. We don't want to figure out what the selectors has to be.

This would dramatically improve the customization of Kendo controls, which I find very hard to deal with in the current state.

Implement automatic suggestion, i.e. suggest() behaviour for Kendo UI Dropdown

Similar to Combobox

It looks like this was rejected over a year ago, but now that this feature is appearing in other frameworks it would be nice to reconsider.

Each tab having its own history is core to making things work like it would in a native app. It is just so sloppy when a user loses their state going between tabs.

You are able to do this with the ionic tabtrip http://ionicframework.com/docs/api/directive/ionTab/ so i would hope kendo can too.

I think it would be great addition to add the ability to set KPI's for the grid & pivot grids in Kendo UI. We have used this on you ajaz & mvc controls but are now migrating to a pure html5/kendo ui based website. Please consider this as a feature for your the proposed controls.  

We have defined a work start and end time for the scheduler. However if the user shows full day in the scheduler we want to make sure the scheduler is scrolled to the start time (when the scheduler is either init or when the user clicks on the show all day button). So basically if there is an API exposed to make the scheduler scroll to a given time then this will work. Please also refer to ticket#: 845019

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.
