Our apps require refresh of the grid's underlying dataset every 15 seconds. By default, this refresh expands all groups. With a couple of enhancements to the grid, we can create a map of collapsed groups and recollapse them after a call to dataSource.data(someNewFreshData). We need two events, groupCollapse and groupExpand. And the k-grouping-row needs a custom data attribute data-k-distinct-values which contains a JSON representation of the array of distinct data values of the current group. For example, if the grid were grouped by state by city by zip, the custom data-k-distinct-values attribute for one of the groups in the grid might contain this hypothetical data: "['California','Beverly Hills','90210']". WIth these complementary enhancements, we'd have all we need to store a map of collapsed groups that we could use to fnd these groups again after a call to dataSource.data(someNewFreshData).  The new data has the same schema as the previously bound dataset.

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.

Kendo UI layout is not working correctly in IE 7

It would be nice to have a wrapper for RadChart to Kendo DataViz or extend RadChart to use SVG and VML to have animated charts like the ones on Kendo Dataviz

I want to have more options for tooltips that work like facebook's tooltips - you get a box, a strip at the bottom w/ buttons. I would like this for the modal windows as well as any tooltip/menu item. 

Some sort of scaffolding for adding buttons to a flyout window component.

Input Mask is very  basic requirment but Kendo UI dont have such Mask Controls.

It would be a great idea if the kendo ui grid has the ability to freeze numbers of columns and rows when scrolling. 

This will allow the user to have the ability to keep for example total etc to be always shown. Those frozen columns will probably not included in the sort. 

There is a bug when cancelling the edit of a row that was loaded through virtual scrolling from a remote datasource, the row disappears from the grid/datasource. Telerik confirmed they can reproduce the bug but due to the specificity of the virtualization process currently do not plan to provide a solution for this. Their recommendation is that if you need editing with a remote datasource to disable virtual scrolling and enable paging instead. Vote for this to have the bug fixed.

In a kendoTreeView if I define the dataSource as an observableHierarchy, then expand(".k-item") expands only the first level but if I execute it twice!!! it works correctly

I have a master detail grid and simply would like to place captions on them.

The js executes successfully, but the captions don't appear when the View is fully rendered.

Grid._toolbar function:
toolbar = isFunction(toolbar) ? toolbar({}) : (typeof toolbar === STRING ? toolbar : that._toolbarTmpl(toolbar).replace(templateHashRegExp, "\\#"));
if toolbar a function, you don't escape # characters, which results in invalid template function generation

Scrolling using the scroll bar works just fine.

There is a error in the grid demo http://demos.kendoui.com/web/grid/index.html. This is in the Virtualization of local data section. The Error says "stop running this script? A script on this page is causing IE to run slowly. If it continues to run, your computer might become unresponsive."

In documentation and examples, its mentioned that Kendo UI Menu can be accessed on client using $("#menu").data("kendoMenu") , which doesn't work

it's actually $("#menu").kendoMenu().data("kendoMenu");

Multi-column Headers like the asp.net ajax grid

There are some bug on parseExact function where check literal return value is not checked producing as consequence that invalid dates are accepted.
You can see this in http://jsfiddle.net/OnaBai/LnaTq/1/
Where I show that a date as String that equals to 2012-09-26 and parsed with format HH:mm is recognized as Jan 01 1900 20:12:00
because the 2012 gets converted into 20 hours and 12 minutes.
As I mentioned above the bug is due to the fact that checkLiteral return value is not tested in parseExact function allowing the execution to continue skipping the ':' of the format string.
If you want me to send you fixed solution I have already implemented it. By the way, watch out that all but one checkLiteral should be checked for false.

Kind of common header to few columns
