We find with lots of UI vendors put up cool demos, but rarely a more realistic view. We like to see the controls in a LOB style layout with:
1. A Purchase order where you enter PO#, Date, Customer (Autocomplete), Customer Name (as result of autocomplete select), ShipToCountry.
2. Order lines (grid or other) with ProductID (autocomplete which then populates description and price), Quantity (which in turn calculates line price).
3. As a result of ajax submit, the server side validation returns error saying order value exceeds customer limit AND ShipCountry not valid for this customer. So the form displays message "Exceeds customer limit" and ShipToCountry input is highlighted with error message "Not valid for this customer".

And make it look good!

Standart scrolling in windows sucks (and takes mush space).
,Kendo Grid has to have designable scrolls, pls :)

hi, we are trying to create part tracking dashboard in mes tool. we want to have stacked bar plus  marker to track the shipping and stock level.  but we are finding the combine chart feature in this tool. kendo ui support team was reviewed our requirement in future.

We were recently going to upgrade from Kendo 2012Q2 to 2013Q1. Unfortunately we can't because we require support for IE8+. 

Our issue is the grid's dataItem method. In IE, it's just too slow. In order to use the newer version of Kendo, we have to upgrade to jQuery 1.9.1 (supplied in the Kendo package). In some cases, the selectors you are using are 13x slower than they were in jQuery 1.7.1.

http://jsperf.com/jquery-1-9-performance-issues

In the dataItem method, you're using the ">" selector instead of children. This, coupled with :not causes this method to crawl. 

In the jsperf test I linked above, I profile many different scenarios. You might want to take a look and see if perhaps you can make use of the .children() method and .not() instead of :not in future releases.

We want the Grid fix the remote virtual scrolling with groups. 
In this case the Grid stay launching requests indefinitely.

If you need to draw a horizontal line in Kendo DataViz Chart (to express desired target value for budget consumption, for example), you have now only two possibilities using line series or plot bands. Unfortunately both approaches have drawbacks:

1) Using additional line series
In this case the line doesn't start at the beginning of the image of the chart, there is visible margin. Also, the determining of number of values for the line series is painful in case you have multiple series with different value counts bind on server side.

2) Using plot bands
In this case the actual width of the band is dependent on the scale of the chart, which can be dynamic depending on data. So this approach is not usable if you want a line width specific width.

What we need is draw a simple line with given width, color and brush.

Allow the user to execute certain methods of the widget and inspect the result.

I would like the ability to make the End Date filed optional when creating a recurring appointment via the Kendo Scheduler.

Little Square handle in the corner of a cell to repeat / increase counter (numeric/date)
Just like Excel.

Hi Kendo UI Team,

maybe in the future, you can add offline documentation bundled with the downloaded package, i think it would be nice, thanks

Implement Excel-like functionality of selecting a cell, selecting the bottom right corner and then dragging down to either copy the value (string) or increment (number).  This feature saves a lot of time and is the main reason we use custom Excel apps as database data entry tools.  Implementing this in Kendo would allow us to migrate to the web

LESS is a very good idea to use, makes Kendo styles much more readable! However, right now the LESS syntax used to generate styles (ThemeBuilder for example) use a non-official branch of LESS syntax. Unfortunately this makes LESS impossible to compile any other way than using the changed JS libraries and harder to integrate with other LESS in the project.

I suggest you either convince the LESS community that the changes are good and merge them into the official branch or consider the possibilities to use official LESS syntax.

The Editor widget would be configurable to support (GitHub Flavored) Markdown syntax and would optionally display a live preview of the text.

A gantt chart would be a nice addition to the too lset.

Steps to reproduce the bug

1) create a grid that uses “In Cell” editing and have a validation on a cell (in this example i will use a required field)
2) click in the required cell
3) click out of the required cell to cause the validation error to fire
4) click back into the cell which had the validation error
5) press escape 
6) click into a different cell and enter a value
7) click out of the cell 

This will cause the cell the be edited but it will not be marked as dirty!!!

The issue is that multiple submit handlers are getting assigned to the form I’ve updated the following to remove submit handlers after submit has been called.

I made a change to the telerik.grid.editing.min.js file to resolve the issue.  setting the submit handler to null after submitting the form seems to do the trick

_validateForm: function (n) {
            var o = this.form();
            if (o.length) {
                var p = o.validate();
                if (p) {
                    this.validate();
                    p.settings.submitHandler = function () {
                        n();
                        p.settings.submitHandler = a.noop
                    };
                    o.submit();

                    p.settings.submitHandler = null;
                }
            }
        },

Please provide a way to display multi-line labels in the chart controls such as the bar chart category axis.  The need is detailed in this post:

Hello,
I try datetimepickerfor control on a mvc project, I set min and max values for it, when I change time, it validates for min, max values and changes automatically but not for date, so I had to write script below. 
Regards.

function dateChange(){
        if (this.value() < this.min()) {
            this.value(this.min());
        }
        else if (this.value() > this.max()) {
            this.value(this.max());
        }
    }
