Look at the Telerik AJAX controls to start implementing in KendoUI as well like the list below. Now some wouldb probably only be used with the server wrapper like Captcha and Zip Library.

- MediaPlayer
- File Manager/Explorer
- Barcode
- Gauge
- Image Editor and Gallery
- Social Share
- Ticker
- Zip
- Captcha
- Etc.....

I think that many great ideas are already presents into the Telerik Asp.net Web Suite and that many of them MUST be "imported" (as soon as possible) into Kendo UI. Controls like SocialShare, File Exporer, Image Editor, Lightbox etc are some "must have" that will be fantastic to see into Kendo UI. Or for example having many of the Telerik Ajax Editor features into Kendo UI editors can be take into account.  I suppose that trying to unify the "Telerik Web Controls World" can help future implementation (sharing things like XAML and Silverlight also if more difficult but maybe its easy for client side) and developer technology adoption or mixing. I suppose that "importing" some of these features and controls is faster than start from scratch. I know that is a generic suggestion and i cant hope to see a completed comment for this (but it will be excellent also for partial results) but as Microsoft is moving into One Asp.Net it will be a great things see Telerik going to a One Web Telerik Suite talking at an high level abstraction. If a web control is usefull in asp.net it will be also for kendo ui its only implemented in a different way.

Enable users of kendoCharts to show only integers on the valueAxis.

Plotband functionality for RadHtmlCharts in UI for Asp.net AJAX definitely needs the ability to add tooltips and labels, otherwise the plotband is meaningless.

add a popup selection box control

Please consider adding the onRowSelect event back to the grid so that it functions like it did in the free telerick code before Kendo. 

In Kendo If you have data and buttons (edit, destroy) on the same row: if you click one of the buttons it will act as if you clicked the data to select it.  Also, you have not provided any documentation as to how to work around this kind of problem.

I am adding i18n to an application to support 22 countries.  The data-title does not appear to be able to be set via JavaScript.  I have a highly dynamic application and I'm using localization for all labels and need to change the titles on the fly.

Please add generic versions of DataSource and ObservableArray to the TypeScript definitions file.

Some strict JS parsers (eg. YUI minifier) may throw exceptions when you use reserved words as variable names. Please, do not do this.

The ability to specify the width of the Ranges in a radial gauge would be beneficial to customize how the gauges can be displayed

I want to display tooltip on category axis of chart on mouse hover event, instead of click event.

I have short list of things that are either broken or not implemented.
1) Merging cells with formulas causes them to disappear (Big Bug)
2) Named Cells (Aliases) don't exist like in Excel (Limitation)
3) Changing row height causes bizarre effect where active row no longer lines up with row number (Bug)
4) Can not hide worksheet or create readonly cells (Limitation)

Please impliment a simple way to display errors in tooltips for every control to prevent form cluttering.

Hi, We have a client request to show week number in kendo ui scheduler timeline view and month view. 

Thanks, 
Lilan

Currently a bar linear gauge can only be drawn from minimum to maximum, but a start position (center) to draw left/right or up/down would be welcome.

The possibility to group line series stack in Chart.

Currently, you can enter a time in the DatePicker and date in the TimePicker. 

The expected validation should not allow this. A DatePicker should only allow a date and the TimePicker should only allow a time.

This would be helpful as I deal with smaller map features
