problem seemed to resolve itself - by replacing old jquery-1.4.3.js with a new copy

The ObjectContext instance has been disposed and can no longer be used for operations that require a connection.

I don't understand the internals,
I've had the grid up and running, then I added the DataKeys (2 of them, I hope it is right) and the Ajax databinding,
added the functions to the controller (hopfully I did it right also)
and tried to run - I got this exception in Html.Telerik().ScriptRegistrar() in the master page.
Here is the grid definition:

Html.Telerik().Grid(Model.ItemsInOrderList) 

.Name("ItemsInOrderGrid") 

.DataKeys(dataKeys => dataKeys.Add(e => e.OrderID)) 

.DataKeys(dataKeys => dataKeys.Add(e => e.ItemID)) 

.ToolBar(commands => commands.Insert()) 

.DataBinding(dataBinding => dataBinding.Ajax() //Ajax binding 

//Home.Index renders the grid initially 

.Select("ItemsGridAjax", "Orders", new { OrderID = Model.order.OrderID }) 

//Home.Insert inserts a new data record 

.Insert("InsertItemsGrisAjax", "Orders", new { OrderID = Model.order.OrderID }) 

//Home.Update updates an existing data record 

.Update("UpdateItemsGrisAjax", "Orders", new { OrderID = Model.order.OrderID }) 

//Home.Delete deletes an existing data record 

.Delete("DeleteItemsGrisAjax", "Orders", new { OrderID = Model.order.OrderID }) 

) 

.BindTo(Model.ItemsInOrderList) 

.Columns(c => 

{ 

c.Bound(o => o.ItemID); 

c.Bound(o => o.OrderID); 

c.Bound(o => o.ItemDescription); 

c.Bound(o => o.NumOfItems); 

c.Bound(o => o.CostOfItem); 

c.Bound(o => o.TotalCost); 

c.Bound(o => o.SupplyDate); 

c.Command(commands =>
                                {
                                    commands.Edit();
                                    commands.Delete();
                                });

})
