Currently if you have combos that are bound via MVVM or knockout etc and have a kendo data source on them for doing suggest lookup they will query everything without a filter to get the display value for the bound value that is set to the value property of the combo.

I should be able to pre-populate an initial set of data on the datasource which it will use when the value property is set. If and only if it isn't set, it should then go and do an odata query with filtering for the specific item and only the specific item based on the field that the dataValueField is bound to, not everything.

Further the combobox and auto-complete should cache data and searches previously done so that it doesn't have to hit the data source again in these scenarios as the user types.

Add a visible property to the column items for the grid control. Then provide the value in the view-model. This would allow us to declare the columns in html and manage their visibility in the business logic.

Excellent work, I think (one/two way) form data binding with JSON/XML serialization will be very helpful. Templates are good but need to support attribute based data binding expressions without templates.

can you advise if the upcoming mvvm framework can be replaced by knockoutjs and / or work with it. we have invested heavily in ko and love it as an mvvm framework. we have also started to use kendo to replace telerik mvc (where appropriate) but would like to know if we can ensure that all 3 products will work together... telerik for server-side UI, ko and kendo for client.

Mapping xml with namespace prefixes is not currently possible.

Basic XPath predicates should be supported (no less than is already natively supported by jQuery).

Kendo UI should have first-class support for XML.  As it stands, Xml support is currently second class to JSON.

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.

I have a Site http://www.amb-selfiesquaregurgaon.com/ . Can i track its page views,browsing time and any other statistical methods on this..can you please suggest me how can i achieve my goal.

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...

When calling the update method on the grid the update is being called after read.  When using a pop up modal to update a row that using a hidden member of the model as an id the display name isn't updated and the update call is actually firing off after the read so the value on the grid looks unchanged until you sort or refresh the page.

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.

It would be nice to have the IF and IFNOT bindings like KnockoutJS has.  It would help keep the DOM cleaner instead of having to use the Visible binding.

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
