Currently templates are only supported when the DropDownList is in an open state.  Ideally, the DropDownList should have the ability to display a template when in a closed (selected) state as well.

A common use case is to display icons next to the dataTextField.  However in it's current state, when an item is selected the icon is no longer able to be displayed.

In window widget I create links and buttons. On pc system it's work correct. But on mobile devices (just like iPad or Nexus 7), these click events is so hard to touch. Other click events outside the window widget is easy to click(the same links or the same buttons).

Allow pinch to zoom images to start zoomed out.  The "pinch to zoom" feature demonstrated at  http://demos.kendoui.com/mobile/view/zoomable.html is useless for most practical applications.  Go to the camera app on your phone and look at photos you took - they start zoomed out and then you can zoom in on them if desired.  If you had to zoom each one out to look at it, that would be incredibly obnoxious.

Add support for drawing box plots (aka box-and-hiskers).  Include capability to display outliers.

When the grid is refreshed with grid.refresh(), regrouping and resorting is not done automatically; as a result, any updates to the underlying dataItems that affect sorting or grouping are not reflected in the grid. That level of control should be available to the developer. Therefore, I would like to suggest that the grid.refresh() method accept an optional configuration object:

var options
 = { resort: true|false (default), regroup : true|false (default)}
grid.refresh( options )

In this way, if the grid is groupede by [department] for example, and the [department] of certain rows is changed programmatically via dataItem["department"] = somethingDifferent, when the grid.refresh ({regroup: true}) method is invoked with the optional argument, the grid would be regrouped, reflecting those changes to the rows' dataItems.

This bug is visible in your demo at http://demos.kendoui.com/web/grid/editing.html.

When using a scrollable, editable grid in IE (9 or below):
•	Scroll down so that the first row of the grid is no longer visible.
•	Click on any row.
•	The grid jumps back up to the original "unscrolled" position. (In your demo, on my screen, this means that only the first 10 rows are visible.)
The result is that I am unable to edit any row outside the first 10, unless I use the keyboard to navigate.
This does not occur in Firefox, Chrome, Opera, or Safari - only in IE.

I believe TabStrip is not supported with SplitView as SplitView can not be used in a view. This is inconsistent if the application needs a common TabStrip across all pages.

Attribute binding is how MVVM should be implemented but currently the following limitations have forced me back to widget-binding ...

1. Some data attributes are not supported (eg. grid "autoBind")
2. Attributes cannot refer to external templates and these must be defined inline.
3. Line breaks are not supported making long inline definitions hard to read and code.

I suggest attribute binding (and documentation) is developed in parallel with widget binding.

Any update on this?

Fix issued described in support ticket 634770 

Sorting accented characters currently is not supported out-of-the-box and we must use ServerSorting to be able to custom sort the items and send them to the Grid. 

The grid should sort accented characters directly on the client. 

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

If I use text method for changing the text of a node in a treeview, the icon gets removed. Same happens if the dataSource is an observableHierarchy object and I use set("text", newText).

Placeholder is supported for numeric text boxes, it would be nice if placeholder could also be supporter for all text box input, i.e. plain text.

In the NumericTextBox typing the character "-" is not allowed meaning that the user can not directly type a negative number.  The only way for a negative number to be specified is by clicking the down arrow to progress below 0 to get the dash to show up.

Integrate with breeze.js (www.breezejs.com/). Kendo UI needs better change tracking capabilities and unit of work support and automatic fix-up of navigation properties. Kendo UI's DataSource only deals with entities of a single type. Kendo UI's ObservableObject tracks whether an object is new or dirty, but not whether an object is deleted or detached. On removing items from Kendo UI's ObservableArray, items are not marked as deleted. Etc.. Breeze.js' entity manager deals with entities of all types, tracking their changes, fixing up their navigation properties, and submitting their changes in a single unit of work.

Adding a SortExpression property to the columns including template and bound column types would enable users to sort on template columns and override the default sort for bound columns.

Didn't found Icenium UserVoice, so i am posting this here.

Support for third party plugis for PhoneGap (Which are JavaScript wrapper and Native code (Java/Objective C) for the targeted platform)

For example, if a user wants to use native Facebook login in his hybrid application, he has to use this plugin - https://github.com/davejohnson/phonegap-plugin-facebook-connect which requires some tweaks in the native code.

Without phonegap plugins, Icenium will fall behind the standart dev stack.

Have a way to remove padding from the Kendo Chart. For asthetic purposes some charts need to fill the entire area. Currently all of our area charts just have a straight line that comes up out of the x-axis and it looks like garbage. we need a way to remove the space from where the chart area starts and stops and where the actual area chart is contained. It should also be noted that both high charts and jqueryui charts can do this. Most people purchase kendo so they can have a consistent toolset.
