Add rerender method to DropDownList, so that it could be dynamically refreshed after eintire select's HTML was changed.

i have a page with several select lists, and their options can be added/removed/disabled/enabled again based on a quite complex logic, which is easier to implement with DOM maniulation than with calling DataSource methods.

Would be nice to have such a possibility 

Be able to show an empty marker when the value is 0 for the sparkline like in this demo: http://dojo.telerik.com/@tsvetomir/ogiH/2

The demo use a hack to show the marker but it would good to have a real solution.

Your Kendo UI demos are useful, however they lack a basic overview to orientate new comers as to the specifics.  More importantly I would find it useful, and it would be more thorough, to provide examples in both Razor and JavaScript Syntaxes.

Add an Year view in addition to the Day, Week and Month views.

Currently, DataViz charts allow you to set a valueAxis's tick mark increments (increments of 100 would give you 0, 100, 200, 300, etc). I suggest a way to set a specific amount of ticks that your chart will always load, and the data will use divisions to fit the tick amount you set. Example: I want my chart to always display 5 ticks. I have two users, one who has a max number of 100 and the other has a max of 500. For User 1, the chart would set a max of 100 divided by the 5 ticks (so increments of 20). User 2 would get increments of 100 to fit the 5 ticks. 

Please provide "retina" support for Kendo Map.  At this point its kinda "table stakes" for a mapping component - let alone one that you need to pay for.

Enable chart interactive features with Canvas rendering.

Currently it is only possible to display more than one measure on a pivot grid. This is a must have requirement for most pivot grids. Please consider removing this limitation soon. 

I would like to the see a feature wherein I can set additional target lines for a bullet chart. This is helpful in scenarios where I need to indicate a target and benchmark. I was able to see similar questions in your forum http://www.telerik.com/forums/set-target-range and also one on stack overflow http://stackoverflow.com/questions/25303748/kendo-bullet-chart-with-two-target-lines 

Currently I am using v2014.1.416.
I am binding mouseup event with below code.
$('#' + mainId + ' div.k-splitbar').live('mouseup', function(e){
            setTimeout(function () {
                if ((typeof ($fujicracommon) != "undefined") && ($fujicracommon != null)) {
                    $fujicracommon.handleVesselResize();
                }
            }, 200);
        });

Kendo Tabstrip reorder

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

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:
http://docs.telerik.com/kendo-ui/api/wrappers/jsp/grid/column

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
