Like k-textbox and k-button css provided with kendoUI - I would like to have it extended for simple box with title, expand collapse button etc. This may be more like [Group] control in winforms. so we can group the controls and enable/disable it as needed.

I confess that I got surprised after checking Component One "Studio for ASP.NET Wijmo"! They already have super fast controls based on jQuery UI with support for ThemeRoller, and supporting client and server side operations. Why did you decide to go for the client side approach?! Also, the controls work really fast and have nice widgets like differente types of galleries. I hope Telerik decides to go this way with Kendo UI.

TabStrip: Add vertical tabs and activate tab on hover mouse (see the JQuery UI Tools from flow player)

The current set of Kendo DataViz components are pretty nice but it'd be great to have more control over the colors/shading of chart items. This is more important for interactive charts where a user might click on an item, and then a small snippet of code would re-fresh a sibling chart to show more detailed data, etc. Visually you'd want to highlight the currently selected item (similar to the piechart Explode option) with a different color/shade.

Provide us a way to initialize the nodes of a panelbar to expanded\collapsed during kendo initialization instead of after kendo renders it.

One of the important features of any grid based pages is the ability to export the grid data in various formats. It's what is keeping me now from replacing all of the Datatables in my app with Kendo grids.The table Tools plugin for datatables is a great example, providing pdf, csv and excel exports all with aggregates, grouping and basic formatting options. 

I;m hoping the next release has at least csv and/excel exporting options. Please also consider a UI column show/hide feature, again, similar to datables plugins.

I know the Kendo grid will eventually have all of this, but the sooner the better for those of us looking to move projects built with beta products (datatables) with more features to Kendo UI.

Thanks!

It would be nice if either through the framework or the individual widget config settings to be able to identify dependent widgets. For example chain combo boxes or drop downs based on selection (country -->states-->city). Probably auto complete, combos and dropdowns (and list widgets when we have them) would all be much improved with this feature.

Thanks for considering....heck, thanks for asking!

Please consider adding series transitions to charts. Trirand JQ Charts and the new Wijmo charts both have the ability to toggle the series via js. Also, drill down capabilities either via dialogues or linked grids on the same page would be a very handy feature.

Now that the Kindle Fire devices are flying off the virtual shelves, it would be cool to add Silk support for Kindle Fire devices. Not sure how you do that or if it's even possible... just putting it out there.

I do not understand why Telerik is releasing a client-side only version of their controls.  Why are not the ASP.Net Ajax components generate html5 controls like the Kendo UI one? 

I would like the controls that I bought (ASP.Net Ajax) to adapt to the world, this is the reason why we first bought them (to avoid taking care of writing client-side interface over and over again and technology progress).

Please integrate KendoUI to Telerik server controls.

Thanks.

Since now Google started doing it on Gmail, I believe that we'll need even more these features.

Once a theme is created and the css/less code is grabbed, the only way to easily and visually modify the theme later is to input all the old values back into the themebuilder.  It would be nice if there was a way to easily get the values back into the themebuilder from a created theme.  To take a page from jQuery UI, they stick a commented out URL into the theme's CSS that will automatically load the themeroller with all values filled out.  This is extremely handy for modifying themes.

At typical usecase for web applications is to let the user upload and image (portrait, avatar, picutre of real estate etc.) and then resize and crop it to a specific contrain.

An easy widget for handling the cropping and resizing might come handy for many.

There are solution for cropping and also resizing in jquery plugins already, however a successful and pretty combo of the two seems to lack a bit.

I'd love to be able to do fractions in the NumericTextBox

...fractions are numbers too! ;)

Or more flexible:

Allow developers to handle user's click on a DataViz legend item.

And provide the possibility to set/reset the visibility of a DataViz serie not only his opacity.

For the app we're currently building, a chromeless, modal window would have saved us lots of time and coding and there are other applications where this could be very useful (especially in the ad serving industry for instance allowing affiliate marketers to place various javascript widgets on their sites that load remote content, etc). 

It looks like a Funnel chart type is one of the typically missing chart types from many html5 chart libs, currently. 

It's pretty useful and including it in dataWiz would give you a competitive edge towards other chart libs ;-)

Make better kendo framework documentation. Demos are fine but it does not have many of the necessary information.

Update dependencies in documentation + add dependencies info in the beginning of each source code file.
