can the panelbar /tabstrip provide unselect method .this method can unselect all select items

It would be great to have such controls as webparts/widgets to place in a dashboard where we could move them around the screen to reorder how data is presented with option to save/retrieve the layout from a persistent source.

In the dashboard the functionality would be to define a layout where we could add/remove, change position the widgets (like in dropthings or pageflakes). The widgets would contain controls like Kendo Grid or DataViz controls to display information.

That would be a killer feature.

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

View/edit source option to edit raw html inside the editor.

The beta text editor is looking good and has an option to insert images via url.
However for most end users they will need a simple image upload.

The kendoupload means you already have much of the required functionality, it just needs to upload the image and return the url.

Also options such as adding title, alt, resizing and alignment will be good.

We currently use ckeditor and until the advanced image options are matched will not be able to move this over to kendo.

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.
