[Solved] Ajax Binding Question

[bogus]

I am looking at the example and i have one question
<%= Html.Telerik().Grid<Order>()
        .DataBinding(dataBinding => dataBinding.Ajax().Select("_AjaxBinding", "Grid"))
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Bound(o => o.OrderID).Width(81);
            columns.Bound(o => o.Customer.ContactName).Width(200);
            columns.Bound(o => o.ShipAddress);
            columns.Bound(o => o.OrderDate).Format("{0:MM/dd/yyyy}").Width(100);
        })
%>

[GridAction]
public ActionResult _AjaxBinding()
{
    return View(new GridModel(GetOrders()));
}

I get all the orders from the database in memory and using linq i extract the orders corresponding to the current page?
I hope i got this wrong because normally you extract from the database only the records correspnding to the current page, sorting, etc..

Later edit: Because of my long nose i didn't see custom binding which is what i was talking about. Sorry for posting such silly question.
