Asp.net connector + datastore + grid

Hello,
I’m using asp.net connector to populate grid and it works fine. Now I decided to try populating the grid using datastore. But I can’t find any examples with .NET connector. Doing it this way leaves grid empty:

            var mydata = new dhtmlXDataStore({
                url: "url to connector that works on loadXML"
            });
            var dp = new dataProcessor("url to connector that works on loadXML")
            dp.init(mydata);
            mygrid.sync(mydata);

What do I do wrong?

Above code will work, but as url you need to use instance of dhtmlxDataConnector, not dhtmlxGridConnector
