signalR gives the possibility to quasi direct connection to the server side with easy parameter passing and easy implementation.

Add support for automatic polling/refresh on DataSource.
Property: interval in milliseconds

Option to refresh one item from a datasource from the server using a GET request using the transport read url appended with the item ID field value.

See: http://www.kendoui.com//forums/framework/data-source/how-to-refresh-an-item-in-a-datasource-with-server-data.aspx

I am creating a realestate website, I want my url to be readable,

For example my site url is http://sitename/property/3, (3 represents property id)

I want to change it like this link  www.paarthrepubliclucknow.in

Of course they are using id and all. How can I replace "property" with something like "residential-property-in-india" in my url and it should be changing dynamically according to search.

I hope it is clear what I want to do...

There has been many scenarios where I've needed to know when a DataSource finishes a "read" or "sync" operation.

I know there's the global "sync" event that I can bind to, but a lot of the time I only care about the result of one specific sync call. I can use the "one" method to only listen to it once, but this complicates things when I also care about errors. Since I need to register callbacks for both the "sync" and "error" events, and then unregister either one or the other, depending on which event fired.

It's even harder hooking into a "read" event because the DataSource doesn't expose one. I know I can hook into the "change" event of the DataSource, but I still have to guess whether the change event was fired because of read, or because of some other change.

If these methods returned a deferred it would be a lot easier to handle the circumstances where an app needs to do additional things after a "read" or "sync" is completed.

Mobile app should be able to save the data locally in the mobile device and  when online network status is detected, should have the mechanism to synchronize the local data back to the server. I asked this during the webcast demo about supporting the html5 local web storage or the html5 indexeddb.

I know you're continuing to improve the kendo/angular integration, but with the rise of full single page applciationsI think you need a deeper integration between the data source and the use of $http (ie services or resources), to cater for such things as custom http headers (for authentication/authorization, application state, etc), which are often set using http interceptors. A typical example is an authentication token.

I'd rather use the grid & data sources' built in functionality such as just setting the url for the source of the data, but this doesn't allow any way to set custom http headers to have the auth token sent along with the request. I see two options:

1. Allow the dataSource to use $http directly for its transport, thereby piggy-backing ontop of the angular http architecture.
2. Keep what you have and allow the requestStart event to have access to the HTTP Headers collection, thus allowing us to modify them before the request gets sent.

We are evaluating migrating from Asp MVC to KendoUI (MVC), which looks promising. However, there is one BIG problem we have encountered: 

Cell values of null are displayed as "Null" instead of as ""! I really urge you to change this since this would require large changes to very many places otherwise. At least an option to select the behaviour.

Thanks

Add support for Web Sockets to enable push notifications to grid, listview, and other data bound widgets.

If possible, please consider making the Kendo DataSource compatible with the data returned from using an ASP.NET MVC 4 Web API project possibly by adding a 'webapi' dataType.

Like many other Kendo components, the treeview is not mature enough to be considered to display dynamic hierarchical data in a LOB application (features limit its use to a static web site).

I can only recommend to urgently add databinding to a datasource. Then you will have to consider loading the dataSource on demand. See http://demos.telerik.com/aspnet-mvc/treeview/ajaxloading

Will you be doing something like KnockoutJS?

I was using DataSource.Read with additional parameters to get data from server to load grid. It was working fine with Q1. But after upgrading libraries to Q3 it is not working. It passes "null" parameter value to controller.
