Similar functionality to the jQuery UI sortable feature.

In the long term, SPA features are absolutely necessary, especially when it comes to HTML5 apps (also in regard to Windows 8 WinRT or upshot.js - a key part of the forthcoming Microsoft RIA stack). 

A good SPA addresses the following issues:

- real permalinks
- page titles
- a working back button that fully degrades 
- different data states like http://bit.ly/zpybmz
- client side caching
- asynchronous updates/communication
- ...what else? (please add if I missed something)

I was really looking forward to using Kendo UI Mobile, but the one control that was critical for my idea was a slider, which is missing from the Mobile package and, apparently, not even on the roadmap.

Lightbox is the most way to show pictures, so I want KendoUI include it and expand. It can be show images, gallery, flash, video, audio even dynamic HTML & external pages, and can be play, pause, previous, next, close and so on...
This is the plugin I used: http://shadowbox-js.com

Knockout.js is a de-facto standard.
It would be nice if KendoUI supported Knockout so developers could use just one paradigm of bindings/observables/templates/etc.

I want to resize the splitter height but only when resize has stopped.

When setting the value for the rich text editor, if the object value is null, it blows up. I have to check if the value is null and if so, set it to an empty string. 
var propValue = linkData[propertyName];
                        var editor = $(this).data("kendoEditor");
                        if (propValue) {
                            editor.value(propValue);
                        } else {
                            // clear value
                            editor.value( '' );
                        }

Add spell checker to the new Rich Text Editor similar to the other Telerik Editors.

I need to be able to filter grid items similar to how it is done in the ASP.NET AJAX controls where you can setup filtering for each column. I have made the Telerik ASP.NET Ajax Grid control to be 100% client side with virtual paging / filtering using Linq filtering on the client to server ajax calls. The Kendo Grid I think is almost there. I just need to be able to do filtering and then I think I will have the functionality that I have now.

The validation can contain fatal errors ( form submit is not allowed ) and warnings ( form submit allowed ).

For example blank/short password is a warning, beacuse it allowed but not unadvisable.

To produce the bugs:

Edit a cell value then the red mark appeared.
 Edit another, the mark is on both cells.
 Click on the first cell, not modify just click the 3rd cell, and the modified mark is disappeared. ( but the cell still modified from the zero state )

Edit a cell value then the red mark appeared.
 Insert a new row, and the mark is disappeared too.

Sorry my English is bad.

Could I suggest a better integration with Phonegap like:

- desktop utility app to package Kendo UI Mobile app into installable packages for iOS, Androind etc..

It would be nice to be able to adjust the values of min, max and step after widget initialization. 

1. Select all button
2. Remember selected items (now they are gone if we change page / scroll in virtual scrolling mode on)
3. Selected items count displayed on bottom bar (for example put it as neighbor of paging list)
4. Copy content of selected rows in grid (ctrl+c when selected) [data split with semicolons]
5. Export Selected/Filtered data into CVS file

I've implemented a large list of options in a listview that I expect a user to select one from.
I am detecting the selection by the 'click' event, but this fires even when the list is scrolled.

I've experimented with the Kendo UI on my iPad, with the VoiceOver feature enabled and some of the widgets work well, but not all do.
Adding support for VoiceOver would add a huge level of accessibility to our apps.

Editing raw HTML is sometimes very useful

I think it is a common thing to use a double click event while using a grid, i don't know why you guys haven't implement it yet

A means is needed to zoom the content view area of a document while leaving the header and footer (tabstrip) stationary.

Currently Kendo UI Mobile puts meta tags in the HEAD of the document, effectively preventing zooming and pinching altogether.  It would be nice if a widget or tool were made available to allow zooming of specific page elements.

For example a guestbook, I want to show the first 10 entries, when the user hits the "show more" button, the next 10 will be loaded and added bellow the first 10. Again, you can push "show more", loading the next 10, append them to the bottom of the list... till no more entries will be received by the server.
