What a revolutionary concept, I made it myself!

would be great to have the option to set an image in a datagrids title, or alternatively be able to specify a title-template (like row-template but for headers)

Date and Time Validations & Row Selection in Grid with Checkbox to Enable Delete and Update the Selected Rows

It makes sense that grouped grids should be sorted by the group name for proper paging, however, it would be nice to be able to sort by group name THEN BY another field. Wouldn't mess up paging.

Really Meant to Say "Add a CandleStick Chart"

Elements for trivial 2 choice radio buttons like show/hide, Yes/No, etc... Of course i can use radiobuttons but for this trivial task somethong like iPhone on/off button would be more intuitive. 

At present there is no method in the grid's public API to insert an item (i.e. fully populated new row) into the grid programmatically, that is, as distinct from visual edit mode using addRow().  

There are methods to update the dataItem, and to remove an item, but no counterpart method to add an item exists. 

There are many use cases for this method; for one possible use case, please see this thread:

http://www.kendoui.com/forums/ui/grid/how-to-append-a-row-programmatically-not-in-edit-mode.aspx#2442552

For my purposes, it would be optimal if the requested addItem() method did not destroy the UI state of expanded/collapsed groups.

After it has been inserted, the item needs to behave exactly like all of the other rows in the grid: it should be "observed"; it should have a data-UID; it should have a corresponding dataItem; be included in grouping, sorting, filtering, etc etc.

we need the polymer js which is used in Kendo UI
like Angular js we need to use Polymer also

The current drop-down list works great.  However, in situations where the options are hierarchical there are (at least) two obvious solutions.

1) Have two drop-down lists (perhaps with some js altering options based on selections).

2) Display a tree of options from the drop-down. (much like a menu)

Here is an example of #1

Here is a very good example of option #2
http://www.givainc.com/labs/mcdropdown_jquery_plugin.htm

The advantage to #1 is that you can easily fire off js after selected options. 

The advantage to #2 is that you can determine all available options on the server and return a structure for rendering.  Also, #2 does not take up more screen real estate. 

I think addressing these interface scenarios would help Kendo become even more usable than it already is.  

Thank you.

The ToolBar widget should provide full keyboard navigability. 
All buttons and split buttons should be accessible using the tab key.
All menu buttons should be accessible using the arrow keys when focus is on the associated split button.
Pressing the enter key should execute the buttons' associated functionality.
The toolbar's overflow menu should support keyboard navigation.

 the splash image while loading the web app initially, well, at least for the ios devices.

Routing is important for building single page apps which is missing from framework right now. 

Routing component of Backbone is very nice. Simple and intuitive. A library similar to this that is integrated into the core framework would be great.

In case there are a couple of opened modal windows(win1, win2, win3, win4) after destroying one that was closed(win5) – two next in chain(win3 and win4) becomes enabled, instead of only the last one(win4).

I’ve analyzed the code of method kendoWindow.destroy and found following lines 

if (shouldHideOverlay) {
    that._overlay(false).remove();
} else if (modalWindows.length > 0) {
    windowObject(modalWindows.eq(modalWindows.length - 2), that.options.name)._overlay(true);                 
}

It seems that line 
modalWindows.length - 2 
should be changed to
modalWindows.length - 1
as modalWindows holds currenlty opened windows, and overlay should be turned on for the last one.

Currently, hashBang (#!) is supported in mobile but it can only contain view_id, it can't be configured as path although it is available in SPA.

It is limiting the SEO capabilities. Support for the following url scheme will be big boost to SEO optimized urls.

/view_id/:category/:item/

Would be nice to have a way to easily configure columns to be fixed (position and width), like a checkbox column to select rows.

This kind of column need to have fixed width and position (cannot be reordable).

But, KendoUI could has also a native support for rows selection, allowing us to just turn on this feature that could have a lot of sub-features: Remember selected rows by page, mark/unmark all, custom options in the column menu to massive mark, and so on.

add server side wrapper jsp for mobile, support MVC binding, when server side data change, mobile side widget auto change

Native mobile tabstrips each have have their own set of views and history per tab.  So for example if you are doing work on one tab, then click another tab, returning back to the first will show everything as it was before leaving.  


kendo mobile's tabstrip doesn't work that way.  Clicking on another tab destroys the content in the previous tab. It should not do that!  Rather, it should mimic the behavior of a native tabstrip.

We find with lots of UI vendors put up cool demos, but rarely a more realistic view. We like to see the controls in a LOB style layout with:
1. A Purchase order where you enter PO#, Date, Customer (Autocomplete), Customer Name (as result of autocomplete select), ShipToCountry.
2. Order lines (grid or other) with ProductID (autocomplete which then populates description and price), Quantity (which in turn calculates line price).
3. As a result of ajax submit, the server side validation returns error saying order value exceeds customer limit AND ShipCountry not valid for this customer. So the form displays message "Exceeds customer limit" and ShipToCountry input is highlighted with error message "Not valid for this customer".

And make it look good!

Standart scrolling in windows sucks (and takes mush space).
,Kendo Grid has to have designable scrolls, pls :)
