I find ButtonGroup for mobile framework very useful to desktop (classic) web application too.

Could you add this widget to web framework please?

An important configuration is to choose if have comportament like "checkboxlist" or "radiobuttonlist", and for sure its orientation, vertical or horizontal. 

For example if you use grid in Client mode it's use case sensitive sorting without any post-back to server which is real cool. But in situation when you need to export grid data to(csv, pdf...) you can pass sorting options from grid to server, collect all data from DB and create exported document. BUT for example SQL server use case insensitive default sorting, so exported documen will not have same data order like grid.

Currently it is not possible to define a DataSource using ASP.NET MVC wrappers and assign the same shared DataSource to a Grid and Chart control (common scenario for reports where you want to visualize the data in a small chart above the grid). The only solution currently is to make two separate calls to the server (and define the two identical data sources twice) which is fairly expensive in a reporting scenario where there's more data that needs to travel across the wire sometimes instead of simple CRUD/transactional scenarios...

Implement the ability to define custom commands in the grid command in ajax binding.

Support drag and drop in the MVC Wrapper for the Kendo Grid.
1. Be able to drag and drop rows within the same grid to change the order of the rows.
2. Be able to drag and drop rows from one grid to another.
3. Support multi-selectiong of rows and dragging and dropping them
4. Customize drag and drop events for the grid.  Example: When dragging rows from one grid to another, be able to modify the drop functionality.

Since the new grid only works with kendo validator, it is important to support all the same jquery validate features that work seamlessly with MVC. The old telerik grid worked just fine with remote validation.

Currently when a grid is bound to a model with related objects and properties via JSON, the grid will only parse the top level object types and treat and related properties as generic objects hence dates are not dates anymore, etc.

Please consider having the grids parse related object properties and data types so there isn't a need for flattened ViewModels in order to properly visualize related data and be able to filter and sort it correctly.

The Q2 release added MVC wrappers for Kendo UI and Kendo Dataviz.  Is there a plan to release wrappers for Kendo Mobile

Ponder? its a basic usability Feature, Kendoui is supposed to be all about usability, surely this is Ponder? There should be a standard (easy/inbuilt) way to show that a grid data source has no records because that is the default opposite to a populated data grid. at the very least if data is empty then show "nothing" all mine does is leave the spinning ajax wheel running forever, so end users does not know, this means i have to write extra code just to implement this, so please consider this "feature"
