I have a grid column being bound to an object.  I would like to be able to filter this column on a sub-property of the object that it is bound to.  In my example I have an object called Division, and I would like to be able to filter on Division.Name.  Currently the filter controls all show up blank when used against an object-typed column.

Its very important to have dynamic binding in the Tree view. Many users are changing the control from Kendo and using other controls because of this. Many large organisations have this problem and both of user and developer is loosing the opportunity to use it.

Throughout the examples/docs for the KendoUI Window component, a variable named 'window' is used to reference the component. This is a terrible pratice, because the variable masks the global window object and prevents the script from acessing it further. As your examples are often used as a starting point for custom solutions, you should rename the variable into something like kWindow or similar. 

It will be great if the Chart Label has hyperlink facility....

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

It’s a web application without server side, which use google javascript Client API to provide additional tools for google calendars management like :
- batch deletion
- generation of recurrent sequence of events.

would be nice to be able to manipulate the grid itself before to data is loaded (wich eventually takes some time).
some manipulations on the grid seems to be irritating, if they are not happend till the full datasource is loaded

Please document that using "validationMessage" as an attribute in a validated control will allow you to have a custom validation message while having a "title" defined. Also, indicate that "Title" will be used if no "validationMessage" is defined.

Instead of pulling the validation message from the Title attribute, use the title in the formatted message. For people who are trying to write localized messages, this could be very beneficial since they can just replace the title with the correct field name and change the message in the options.errors just once for the localized error message.

   _extractMessage: function (input, ruleKey) {
        var that = this,
                customMessage = that.options.messages[ruleKey],
                fieldName = input.attr(NAME);

        customMessage = $.isFunction(customMessage) ? customMessage(input) : customMessage;

        return kendo.format(input.attr(kendo.attr(ruleKey + "-msg")) || input.attr("validationMessage") ||  customMessage || "", input.attr("title") || fieldName, input.attr(ruleKey));
    },

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.

Improve the xml parser so it can handle missing data that is sent in a shortcut manner.  For example, NAME is blank or missing:

<NAME></NAME>

Shortcut manner is

<NAME/>

We can do it using JQuery getJson or .ajax calls but would be good if everything gets unified inside Datasource so all on-screen controls can be bound to a datasource not a specific control.

This will allow the person  viewing the page to get rid of unwanted columns.

Add ability to insert SVG html into Kendo Chart areas like the title. Example would be ability to add my own TSPAN to the title to help style it more.

It would be nice if there was an additional dropdown in the Editor that was populated with CSS classes in my .css file.  It would allow users of the application to style articles and other text consistently by simply selecting predefined styles for that layout.  (Hopefully this isn't a duplicate)

We have a need for a disabled option in the drop down list. I tried it with the Kendo UI dropDownList control, but the disabled attribute was removed in the rendering process.  It is a nice control, but it could use some additional functionality.

I want to ask you to add support for this type of call to kendo.format:
    kendo.format('{0} - {1}', [3, 5]);
Of course this is not useful if you have the parameters in seperate variables.
But it is useful if you get the format and the parameters from some external source and that delivers the parameters as an array.

Provide default mode for Kendo Mobile.

When working in kendo mobile web applications, give the user the ability to specify a default or fallback render mode if iOS, blackberry, or droid are not found.

Implement it much in the same way you implement the platform application property but instead of saying use this platform for all render modes, this property would equate to saying use this mode IF none of the other supported modes within Kendo Mobile are not found.

This also would be good for future development as you add render modes we could response with our "default" style.

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");
