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.

As a proof-of-concept, I have reworked some of the PHP tutorial examples for a ColdFusion CFScript service.

Add the AJAX FileExplorer to the MVC Controls Toolset with additonal built-in features I would like to see:
1. Support for UNC paths so that the root folder may be located in a network share as opposed to a folder under the application folder.
2. Support for sub-pathing so that it can be dynamically programmed to support direct display of target folder without having to navigate to the target folder
3. Built-in Delete function to complement the built-in Upload function
4. Optionally select display of a checkbox column to allow for multiple selection for items to be Deleted or Downloaded
5. Built-in Progress Bar for Upload and Download functions
6. Optionally select automatic filtering of hidden files and directories from the display

Could you please provide a way to change the default 200ms fade:in modal view animation? Ideally it should work with all transitions that a standard view accepts.

This suggestion is related to the following thread on the forum:

add delay parameter in miliseconds for the kendo.ui.progress so you don't see your container blinking if your ajax calls are fast.

add treeSelect   example:http://www.miniui.com/demo/treeselect/lazy.html

When creating a multilingual website I've realized, non-English unicode characters are not supported by the Grid's toolbar buttons. The toolbar won't be created and the Grid's setup cancelled. So, also no read function called or anything else.
Strangely it also killed the functionality of my Razor DropDownList for language selection despite no connection other than both using JavaScript.

I would suggest to enter the function menu script that is described in the following link. This is an interesting application that really makes it easy to navigate the menus user an.

We would like to write a UI using Kendo UI Mobile and be able to still use it with mouse scrolling on desktop browsers like Firefox / IE etc.
