Now that the Kindle Fire devices are flying off the virtual shelves, it would be cool to add Silk support for Kindle Fire devices. Not sure how you do that or if it's even possible... just putting it out there.

I need to be able to bind similar to:

  <%= Html.Telerik().TreeView()
                .Name("TreeView")
                .DragAndDrop(settings => settings
                    .DropTargets(".drop-container")
                )
                .ClientEvents(events => events
                    .OnNodeDrop("onNodeDrop")
                )
                .BindTo(Model, mappings =>
                {
                    mappings.For<Employee>(binding => binding
                            .ItemDataBound((item, employee) =>
                            {
                                item.Text = String.Format("{0} {1}", employee.FirstName, employee.LastName);
                                item.ImageUrl = Url.Content("~/Content/TreeView/Common/contact.png");
                                item.Expanded = true;
                            })
                            .Children(employee => employee.Employees));
                })
                .HtmlAttributes(new { @class = "t-group" })
        %>


and have the functionality of sorting, filtering

It would be nice if you added an option to actually use combobox in mvvm scenario.

Like:  sortable: { mode: "multiple", max: 2 }. When the 3rd one is sorted it unsorts the first.

I have seen a few different samples on how to implement a dynamic skin chooser for Kendo UI Web, but I think this would be a great UI control to be added to the suite itself.  None of the code samples I have found are simply drop in and use, but require slight modifications.

Have the opportunity during the reporting grid columns to add or hide visible property. This then avoids calling the function hideColumn.

By default the column is visible.

Allow actionsheet to be databound to a DataSource

Add support for the HTML 5 data-* so we can access the Kendo API in this elegant and unobtrusive way.

Example, Kendo's date picker could be called this way something like this:

<input type="text" class="myClass" data-kendo-date="true" data-format="dd/MM/yyy" data-min-date="13/12/2013" />

This feature will help a lot then you need to show user a text values but send number values of cells to a server.

Release a guide similar to the jQuery UI one which shows the best practices to develop our own "kendo ui conform" widgets and allow and document the code reuse - like globalization - from our own widgets.

When you click on a tab in a TabStrip, the expand animation shrinks the content area's height to zero, then expands it to the height of the new tab. This isn't bad, but gives a "bounce" effect to the control, which can be offputting (I've had complaints about it from users).

If would be nice if you could animate it from its current height directly to the new height, without shrinking to zero in between. That would be a much nicer effect.

We are using the kendo dropdown widget and noticed that the performance degrades quite drastically if it contains more than 100 items. Can you investigate performance improvements even for larger item sets?

Find Node or search mode

Add client-side filter method that automatically updates the filter menu options (dropdowns and values) according to the filters described in the filter expression.

It would be nice to have a GroupBox widget that we could enable/disable or make visible/invisible groups of controls easily.  Would also be nice to populate via Ajax.

How about a simple addition to zooming, whereby the zoom just automatically zooms into the current data set by filtering off the outer elements? For example, have a zoomStep property, which defines the number of elements to filter off the start and end of the data. This would allow really simple zooming without having to write filters and would allow for easy use in shared code scenarios (eg, we have a single Knockout custom binding for all our charts).

I'd love to be able to do fractions in the NumericTextBox

...fractions are numbers too! ;)

I'm reposting this as a bug since currently when multiple windows are created, the zIndex never gets adjusted like in telerik.window.js hence it is impossible to have dynamically created windows without having to fix the zIndex manually for each new window. And once you adjust the zIndex on one window, it always stays on top.

We are using Metro theme, and many clients say us that is a little bit difficult to distinguish parent from child items in a panelbar because they are too similar. Is possible to introduce an left padding to recreate a fake tree?

I shouldn't be penalized in having to write more code to get kendo validation working with kendo controls.  You guys should know I'm validating a KendoNumericTextBox and auto-place the span in the appropriate spot outside of the control.
