I have an action list that is part of a view bound to a view model. The data-action attributes won't fire handlers that are part of the view model in the same way that a data-bind attribute does. I think that they should as the action list is part of the view.

One other suggestion it to make the description text box (the one I am typing in now) sizable and provide a mechanism for formatting code examples.

As a proof-of-concept, I have reworked some of the PHP tutorial examples for a ColdFusion CFScript service.

Add a css class to the treeview to style an item (change complete background, indent, font-style etc). Currently only a spriteCssClass is available, but is not applicable for the total line. Must be available like the spriteCssClass, so available in datasource.

I want specific column in Kendo UI grid canbe disable columnMenu! Now only can disable sortable and filterable but not the whole columnMenu~

Provide means to specify if a legend item needs to displayed or not, either through a configuration API which can take a condition on the value / series, or through an event when the legend is being added. This will make it easy to manipulate the legends that are displayed. Additionally, having an event to hook into, can also provide means to add custom functionality, like click handling, to the legend items.

Suggested fix

                if (a != null && b !== null) {
                    return a > b ? 1 : (a < b ? -1 : 0);
                }

                if (a == null && b == null) {
                    return 0;
                }

                if (b == null) {
                    return 1;
                }

                return -1;

KendoUI Mobile currently has only back button. There should also be a forward button along with it.

Take a look at DevExpress DXperience...

you can able to change background image in kendo ui slider.

Enable the user to show the icon in a different place than the default. like the right of the text and not juts to its left.

Today, the only way to change the date in kendoDatePicker is to show the calendar and select another date, but in scenarios where i want to allow my user to move one day at a time as defaule, a left arrow and rigt arrow will be great.
same thing holds for the kendoNumericTextBox, althogh he has the up/dowun arrows, they are relitevly small and a Plus and Minus icons to the right and left of the widget will be easier for a fingure to tuch.

Please add a click event to the Chart Legend similar to the seriesClick event that currently exists.

Allow charts to define multiple chart areas.  

This would be particularly useful in scenarios where historical data for an industrial process must be visualized in line charts (e.g. temperatures, pressures, valve positions, flow rates etc.)

It would be awesome if you added masking to input fields, similar to what you've done with validation. Many times I need to add formatting to the display of a field that and I don't want to store the extra characters associated with the on screen formatting. Formatting for telephone numbers, email addresses, currency are the ones immediately useful. Although other libraries exist for these, it would be nice to consolidate them into a single library!

Currently complex elements (Like the Grid and the Chart) have so many properties and methods that the page has so many DOM elements it takes forever to load.

Add support for the HTML 5 data-* so we can access the Kendo API in this elegant and unobtrusive way.

Example, Kendo's date picker could be called this way something like this:

<input type="text" class="myClass" data-kendo-date="true" data-format="dd/MM/yyy" data-min-date="13/12/2013" />

Currently, if a page's font size is just a little bit larger (for example 14px), some widgets do not display correctly. Sometimes the images alignment is wrong, sometimes borders do not fit. As an example, look at...

http://www.kendoui.com/forums/ui/general-discussions/widget-display-with-changed-font-size.aspx

With frameworks like Bootstrap it is quite common that the font size is not too small. So currently it means work to use Kendo and Bootstrap together,

I suggest you either improve the widgets' rendering so they do not rely on a certain font size. Or another solution would be if each customer could create a specific CSS from the LESS by setting some variables.

It would be great to have a Widget that allows you to bind keyboard short cuts to a normal HTML element such as a Button or really an other element.

Additionally upon init, this widget would check for conflicts against other shortcuts provided by Kendo UI and provide the developer an exception explaining the conflict.

the baseUnit options ist great but i need seconds as baseUnit
