I think a Kendo UI plugin for WordPress would be a potentially massive hit with WordPress users and developers. I saw here http://www.kendoui.com/blogs/teamblog/posts/12-02-29/q_a_from_kendo_ui_webinar_q1_2012.aspx that you can use Kendo UI with WordPress. That is great, but an actual plugin would be awesome. Of course there are plenty of ways you could go about it - these are just a couple broad suggestions that come to mind. Offer a free WP plugin available to current Kendo UI customers seeking simplified integration with WP. Or, offer a premium/paid WP plugin to potential customers who would like to use Kendo UI with WordPress site(s) only. 

you can able to change background image in kendo ui slider.

Take a look at DevExpress DXperience...

You can currently set series labels to position "center" on the pie chart to get them to render on the slices, but sometimes slices are too small to contain these labels. It would be great if there were an option for the chart to detect when a slice is too small and render the label outside the chart, while still rendering labels on pie slices that are big enough to contain them.

For these tools to create ID's for all actionable items and allow them to be named(Telerik's Default)or by the developer as the developer creates them.

KendoUI Mobile currently has only back button. There should also be a forward button along with it.

Where several pie charts are displayed above each other, it would be nice to specify a consistent diameter or max width for the legend (when the legend is displayed to the side) to ensure all the pies line up together. Longer legend items then need to wrap.

The loading text of kendo.ui.progress is hard coded. 

Please make it localizable.

Allow multiple header lines in the grid - eg two header lines first line contains four columns the next eight. The first col provides a visual grouping to the second header

Ruby server wrappers. We need it!

Suggested fix

                if (a != null && b !== null) {
                    return a > b ? 1 : (a < b ? -1 : 0);
                }

                if (a == null && b == null) {
                    return 0;
                }

                if (b == null) {
                    return 1;
                }

                return -1;

I would like to be able to configure a tooltip to be shown if the user hovers over an x-axis category. I would also like it to be dynamic based on the category. 

My use case is each x axis category represents a flight, to keep the label succinct I use the flight number, however it would be good if the user could find out more information about the flight such as the date, departure, destination etc.

Currently I put this information in the tooltip for the data series, but when I show multiple data series this text looks out of place and also makes it harder to see the data relating to the data series point.

Provide means to specify if a legend item needs to displayed or not, either through a configuration API which can take a condition on the value / series, or through an event when the legend is being added. This will make it easy to manipulate the legends that are displayed. Additionally, having an event to hook into, can also provide means to add custom functionality, like click handling, to the legend items.

Seems like lots of Chart features are yet to be implemented.  I want to use jQuery to hack positioning of elements like axis titles and replacing some rendered paths with images, but without classes the selections would be expensive and maybe imprecise.

This will help take some of the heat off Telerik while users wait for more functionality in the next release. Let us modify what we need!

I want specific column in Kendo UI grid canbe disable columnMenu! Now only can disable sortable and filterable but not the whole columnMenu~

Big SPA projects need to have an architecture for the code, some structure. Current examples for SPA are suitable for small apps, so some docs/examples/guidelines for bigger projects would be useful.

I can't select date in my kendoDatePicker when I set readonly option or call readonly method. This problem is in the new version 2013.1.319, in version 2012.3.1114 all work perfectly

When displaying a large list (hundreds of items) in a list-view it takes a long time with many flicks to get to the bottom. I've been testing on a Galaxy Nexus, and in my gmail I can get to the bottom of my list of  emails (hundreds) in just a couple of flicks.

It seems the kinetic scrolling in kendo ui mobile doesn't scale well with longer lists, it scrolls the same number of items no matter the size of the list. Whereas the native behaviour seems to keep scrolling for longer and faster, scaling with the size of the list.

Add a css class to the treeview to style an item (change complete background, indent, font-style etc). Currently only a spriteCssClass is available, but is not applicable for the total line. Must be available like the spriteCssClass, so available in datasource.
