Hello,

We are declining this request due to lack of interest and activity. 

That said, additional information can be passed to the Controller by utilizing the Data() method:

Thanks for clarifying.

Note that you can specify the read transport option as a function, as explained in the API documentation (http://docs.telerik.com/kendo-ui/api/framework/datasource#configuration-transport.read). 

Thus you can specify $.ajax call and set headers via the headers attribute, or intercept the beforeSend event as depicted here:
http://stackoverflow.com/questions/7686827/how-can-i-add-a-custom-http-header-to-ajax-request-with-js-or-jquery

I'll forward your feedback for exposing this via the MVC data source wrapper to our devteam.

Nope.. Now i need to set manually in javascript

        grid.dataSource.transport.options.read.beforeSend = function (req) {
            req.setRequestHeader('Authorization', 'Basic abc:123');.

I hope kendo mvc add 1 more helper in grid helper that can call beforesend

I assume you are talking about the jQuery ajax beforesend event here, is that correct?
http://api.jquery.com/Ajax_Events/

And if so, can you clarify what prevents you from intercepting this event when making $.ajax calls?
