Adobe AIR imposes some security restrictions on Javascript code written in certain ways/styles (e.g., use of "eval" and "Function" declaration inside code, which are used in KendoUI), but offers a fairly complex implementation facility (called the "sandbox bridge") so developers can work around these security restrictions... Please provide Adobe AIR/Javascript developers "BEST PRACTICES" articles/tutorials on how to code the KendoUI widgets that are incompatible with the Adobe AIR security restrictions.

There is no way to use tree as a column in a grid.
A TreeGrid would use hierarchical datasource where one column would show nodes and other columns would show node properties.

Here is an example (from Sencha Ext JS)

Is there any way to implement checkbox list using kendo web?

Smart Input.  iOs in facetime has an input that has onBlurEmpty, onBlureChange , onFocus events.  It also manages the style of the state.  It has a bound clear input button that send the caret to the beginning, while showing the preset value . It also has a preset value that is in a different style.

With this widget you can make passive calls to the database for CRUD stuff.  

Look at the contact section in FaceTime.

On this page: http://demos.kendoui.com/web/grid/column-menu.html
See the "Shipxxx" column.
IE can input contents and submit but the menu seems shake.
Other modern browsers can NOT input contents but the menu Not shake.
Please fix both! Thanks~

Add TickDistance, AutoRange and Step to the line Chart like the Telerik RadChart.  When querying a web service and charting a dynamic/variable number of values, the current chart results in grid lines too close together and overlapping x-axis values.  This would space the grid lines and labels based on the number of values and available space.  This is from the RadChart documentation:

The TickDistance has to be used together with AutoRange. When AutoRange is set to True, the axis Step value is calculated depending on the data range, the available space and the TicksDistance value. Since TickDistance defines the minimal distance between two ticks, increasing its value will cause the Step value to be increased too.

Add optional scrolling to Chart like Telerik RadChart Scrolling:

And/Or add a paging feature to the Line Chart that allows the user to page from right to left through data. Use the paging feature of the datasource to allow huge datasets to be viewed in increments (querying pages of data for the chart as the user pages from right to left) for performance.  For example, if a years worth of hourly data is requested, page by month through the chart and query the data from the datasource one month at a time.  This could work nicely with a grid configured for paging using the same datasource to display the data and chart in sync on the page.

AngularJS, which just released 1.0, is gaining a lot of fans (including myself and my developer-friends). There already is an AngularJS adapter for jQueryMobile, and I hope the KendoUI Team will work on an AngularJS adapter for KendoUI very very soon. I think a solid AngularJS adapter implementation will pull my team over to KendoUI for good.

I created a custom theme using the theme builder. I then created a grid (using the MVC wrappers) and included a column menu. When I drop down the column menu there are no sprites drawn for sort, filter etc - there are in the provided Telerik themes. These images should also be included with custom themes.

I've been trying to use these great UI widgets in PHP update forms and the lack of documentation on how to use the datasource and widgets together in PHP forms is incredibly frustrating. Seems like it would be a very small job for one of the kendo gurus to come up with the following and add it to the examples and/or documentation:

Update forms:
In update forms you need to initialize the widget(dropdowns, comboboxes, etc...) with the value of the column in the database and provide the list of options to choose from to edit the data. I assume there is a way to do this using the datasource but there is zero documentation on this. Please provide a simple example with a standard php update form with the widgets pulling the form data from a simple query based on a selected id, just like every standard php form on the web, with clear code showing us how to configure the widgets so that they contain the data from the db when initialized and providing the list of options via the widgets dedicated datasource.

This is very simple stuff and should take one of your junior techs 10 minutes and would make some of us very happy.

Thanks!

See http://www.highcharts.com/demo/line-basic for a good example of  Client-side Chart Export

When the destroy operation fails for some reason (exception or ModelState error) the item on the client will be removed.
Don't remove the item from the grid if operation fails in the backend.
 

and a grids toolbar with the commands and template at the same time throw a search input text that filters the grid. 

Won't hurt to have one, to have a KendoUI version would be pretty in the eyes. 

Addition of the Rich Editor similar to what is found in ASP MVC controls in Telerik

It would be a very cool thing to have a small WYSIWYG-Editor for mobile devices.
As far as I know, there isn't kind of this on the market at all.
So Kendo UI Mobile could be at pioneer-state

Hi,

some of date and time patterns defined for cs and cs-CZ cultures are wrong. The correct patterns are:

d: "d. M. yyyy",
g: "d. M. yyyy H:mm",
G: "d. M. yyyy H:mm:ss"

(dots are followed by spaces)

Web devs have a million different frameworks out there.  Talk about how this differs (or is a companion) from using jQuery UI (looks like it competes), Knockout, extJS, etc...

Sure the IE Mobile browser is not fantastic (even the Mango version feels like it has issues), but will you be supporting the WP platform?  That would round out all the worth while mobile devices in my opinion.
