Add pageproxy at runtime

[78fede78]

The control with ID 'StoreRow_S1' not found





Store store = new Store { ID = "StoreRow_"+id };
JsonReader reader = new JsonReader();
reader.IDProperty = "ID";
reader.Fields.Add("ID", "Name");
store.Reader.Add(reader);


//This is the line that generates error
store.Proxy.Add(new Ext.Net.PageProxy());



How do I add a pageproxy at runtime to an object store???
