DataSource should be more feature rich. I consider following features a must in order to be able to develop complex UI's without the current pain

- Multimple models definition
- Associations between models
   - BelongsTo
   - HasMany
- Lazy load of associations!
- Allow use a REST approach for associations (send updates over a HasMany association to a service)
- Allow send the complete object

- Association validations
   - Unique
   - Exists
   - Min/Max number of elements

I'm using the MVC wrappers, I have a foreign key column in my grid and I use the standard foreignkey editor-template. It is not possible to bind a null value (foreign key not set) to the dropdown. It works when I change the template and replace the kendo dropdown with the standard mvc dropdown.
So I guess there's a problem with null values on the kendo dropdown

As Kendo UI already supports AMD Require, it should also be support CommonJS and Browserify.

ASP NET MVC provides jquery.validate.unobtrusive validation that, using jQuery validation, let us set validation attributes into model class.

Would be nice if it may work also with kendo ui validation.

Within the Grid you can currently either have single-row editing, or batch editing. However, batch editing does not necessarily show the end-user that the Grid is actually editable. In order to make the Grid more intuitive it would be great to have all cells display their edit template constantly to ensure that the client knows they can edit the component.

Additionally, sometimes a user will want to edit more than one row at a time, but not have the entire Grid in edit-mode. Being able to open several items to be edited at once would help with this user interaction.

This is why having multi-row edit, the ability to have multiple rows in edit-mode at once, would be a nice feature to have in a Grid. It would also theoretically open up the ability to have all rows in edit-mode at once.

Hi what is the latest on this please?

Would be nice to have helper/wrappers for KendoUI for ASP.NET MVC 3

Currently when using the Column Menu, there is no visual queue to indicate that the column has a filter applied to it.

The most important part of using Vue especially in Mobile, is it's small size and performance. Unfortunately, Kendo UI's Vue components are wrappers around jQuery which is something we are trying to avoid in our  ongoing developments.
I'd like to suggest building NEW Vue components in full native format with no despondency on other none related frameworks.

Thanks!

It would be great if you could zoom in on the charts like highcharts,
http://www.highcharts.com/demo/line-time-series

A lot of the charting functionality there would be great.

A heatmap (grid-style at least) is very much useful in any decent project management application. A widget that could remotely connect color-shades to jSON data would be really great.

It'd be nice if we could do this through the options and not via a css hack.

In the meantime, here is a way to get around it, provided by Georgi Krustev http://jsfiddle.net/krustev/uZUjK/

Add the ability to reorder columns (and their data) within the Kendo UI grid. This would preferably be handled through drag and drop. 

Developers these days are spoiled with choice when it comes to selecting an MV* framework for structuring and organizing their JavaScript web apps. 

To help solve this problem, www.todomvc.com offers the same Todo application implemented using MV* concepts in most of the popular JavaScript MV* frameworks of today EXCEPT OF Kendou UI...

Ability to have a hidden menu that slides in or pops in much like the other apps and frameworks have.

You have datepicker.
You have timepicker.
Why not datetimepicker?

A single input box that selects both a date and a time.

Should be fairly straightforward, it just needs to display both ui widgets simultaneously and handle the different parsing in and output logic.

Current when using the HierarchicalDataSource you can only load one level of data at a time. I would like to be able to pre-populate the entire tree (but have the ability to refresh it via remote data, should I so need).

We reaally need to use the overlay animation, our client is driving us nuts with it. They are showing us the examples in Jquery mobile panel (http://demos.jquerymobile.com/1.3.0/docs/widgets/panels/) and asking us why we are using Kendo if we cant deliver this animations. 

Please help us voting for this animatiosn.

Buttons and toolbars (with icons and kendo themes) are much easier to use with Touch devices than the Menu widget
