Hi all! I have an anonymous linq query that I bind to a datagrid, when I debug it brings alright the data but it doesn't show in the datagrid, I suspect that the request to RIA services isn't completed before I bound it to the datagrid. I could use the LoadOperation<>() Completed event. But it only works with Defined Entities so how can I do that? For reference here is the last post: http://stackoverflow.com/questions/2403903/linq-query-null-reference-exception Here is the query:

var bPermisos = from b in ruc.Permisos
                                 where b.IdUsuario == SelCu.Id
                                 select new {
                                     Id=b.Id,
                                     IdUsuario=b.IdUsuario,
                                     IdPerfil=b.IdPerfil,
                                     Estatus=b.Estatus,
                                     Perfil=b.Cat_Perfil.Nombre,
                                     Sis=b.Cat_Perfil.Cat_Sistema.Nombre

                                 };

I'm a totally newbie sorry if is a very simple question.

Thanks!!
