This is indeed a possible assumption, iman. However, since the original poster or other guys who joined the discussion have not commented yet, and the SignalR solution is doable, I'll leave the status of the thread unchanged.

@kenshin: I think the goal of people who upvote for this idea was access to properties like "autoRefresh:true" and "refreshInterval:5000" in DataSources to let them automatically refresh the records of datasource instead of manually calling "read" method of datasource.

Guys, note that we already support SignalR and Web Sockets binding with the data source:
http://demos.telerik.com/kendo-ui/web/grid/signalr.html
http://demos.telerik.com/kendo-ui/web/grid/web-socket.html

Does this cover what you request as automatic polling/refresh in this thread?

Did this ever get into the Datasource?  It would be extremely useful to me at the moment.

I'd like to see the datasource components be able to respond to the CouchDB _changes feed, so that any relevant updates to the serverside data can be propagated back into the kendoui datasource.

It rather crude:

pollingTimer = window.setInterval(triggerFilters, $("#pollingInterval").val() * 1000);
	              	
function triggerFilters() {
    grid.dataSource.page(1);
    grid.dataSource.filter([{ field: "logLevel", operation: "eq", value: filterValue },
              	                    	{ field: "_all", operation: "eq", value: $("#searchFilter").val()}]);
		    
}

Can be stopped again using:

window.clearInterval(pollingTimer);

Could you post what you did with your filter implementation?

this could be accomplished via support for SignalR https://github.com/SignalR/SignalR

Exactly. Currently I have implemented my own that calls the filter method at a specific interval. I use with a grid that displays log entries.
