Provide a product migration guide from your sister products (e.g., silverlight controls, radcontrols) which presents use cases such as: "If you have a asp.net radgrid such as...  you could do the same task similarly with KendoUI by..."   

Having complementary examples implemented using your various product types instills a bit of confidence that interfaces created in one environment could potentially be emulated or duplicated in another.  With maybe some best practices or "known gotchas".

My application need the ability to display data using a logarithmic X axis.  Kendo doesn't seem to do this but it is available with Flot using a transform option.
              xaxis: {
                    transform: function (v) { return Math.log(v); },
                    inverseTransform: function (v) { return Math.exp(v); }
                },

The transform function supports many other was of reinterpreting the axis so it does much more than just Logarithmic displays.

I love the look of Kendo.  Please consider adding this to your visualization package!

Tick marks on charts have only been partially implemented.  Add the ability to show major ticks at step intervals (as done with labels) and show minor ticks between the major ones.  Allow this option on all charts (or at least column, line and area charts) and on X and/or Y axis.

Hi.
I find bug in StockChart version 2013.2.716 (2013.2.626 is ok):

$("#stock-chart").kendoStockChart({
                dataSource: {
                    transport: {
                        read: {
                            url: "boeing-stock.json",
                            dataType: "json"
                        }
                    }
                },
                title: {

                    name: "Open",
                }],
                navigator: {

                        field: "Close"
                    },
                    select: {
                        from: "2000/01/01",

I set line series type and json data have null value.

I implemented the Kendo Scheduler widget in a Kendo Window today. The events of the scheduler did not show any resizing handles on hover. It showed up that this problem is caused by a CSS style in kendo.common.min.css stylesheet
where one is applied to .k-window .k-resize-handle (opacity and font size set to zero). Just a little bug, but it took me some time to figure out the cause..:)

all selectable widgets can have clearSelection() method like kendoGrid.clearSelection()

Create a plugin for Oracle APEX that would allow easy use of dataviz and other widgets

Samsung and Intel are releasing new products with Tizen a few weeks from now and are in full throttle promoting it to developers (we actually just started a project for a client who asked to include Tizen tablets as a target device). It might be a good idea for KendoUI to implement full support for Tizen early --- and it might actually NOT take a lot of effort to do so.

It would be good to have possibility to put button groups into multiple lines. Like Jquery Mobile. There is offeten to few space and too many buttons to fit them without multiple lies.

The previous KendoUI mobile listview respected datasource grouping when endlessScroll was enabled. This functionality has regressed in the Q2.2013 release.

An extract from my support ticket 718079:

For our application, it is not acceptable that the ability to group with endless scrolling has been lost. Grouping is fundamental to the user experience in our app - especially when there can be a lot of items in a listview. It is just as important as the performance that endlessScroll enables. One, without the other is a backwards step.

Telerik response extract:

Thank you for your feedback. I fully agree with you - grouping of a large dataset improves the user experience and provides the necessary visual clues for the user to determine the current position in the list. The only reason why this is not supported is the high complexity and performance implications of the task, when combined with virtual mode, which is a requirement for a large list support - our previous implementation easily crashed the mobile browser when 100+ items were displayed. I would like to suggest that you post this feature request to our UserVoice feedback  site; we are actively following the popular items and responding to our customers demand with each release.
---

I do not believe the complexity is quite as high as has been described. The datasource can identify how many groups there are - for any current filters and adjust the endlessScroll height accordingly. The listview items themselves can be adjusted down in position by the number of group headers above them.

I use Durandal/Knockout and Breeze for my PhoneGap mobile App. Kendo Mobile is one of the best looking CSS libraries but cannot work with Durandal.

This sums it up -  http://stackoverflow.com/questions/17758991/where-to-init-kendo-mobile-application-in-durandal/17786286?noredirect=1#17786286

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

The second tab (Sales) has data-stretch="true" set for its view. This appears to throw an error that breaks the drawer for that view. 

hi telerik
It would be great to have a calendar view similar to http://www.almanach.free.fr/ and the ability to add task to a day.

React uses a declarative paradigm that makes it easier to reason about a JavaScript application. React computes the minimal set of changes necessary to keep your DOM up-to-date. 

Kendo UI seems not to have such an update feature. But since React works with most libraries and frameworks, please create an example app with React or make a blog post about how to use React together with Kendo UI Web.

As per forum thread: http://www.kendoui.com/forums/mobile/listview/endlessscroll-with-scroller.aspx

The Listview should look for any parent scroller to determine endlessScroll rather then look at the View's scroller.

Please support the HTML5 History API and stop using URL fragments for both general use and SPAs. URL were, and always will be, a hack (although necessary previously) and there is enough support for the History API now to move to it. Even Facebook is using it, so there can be much concern for support. :-)

It would be nice to be able to have log scales on gauges.

Native mobile tabstrips each have have their own set of views and history per tab.  So for example if you are doing work on one tab, then click another tab, returning back to the first will show everything as it was before leaving.  


kendo mobile's tabstrip doesn't work that way.  Clicking on another tab destroys the content in the previous tab. It should not do that!  Rather, it should mimic the behavior of a native tabstrip.

When sorting a foreign key column on grid, the sorting is performed using the value/id - which is wrong. The sorting should consider the text displayed to the user.
