Fill just some DataView columns with IEnumerable

Question

I have a method which returns an IEnumerable of some custom type.

 public IEnumerable<_Persona> RegresaBusquedaPersona(string nombres)
        {
            return context.personas.Where(x => x.Nombres.Contains(nombres) ||
                                            x.ApellidoP.Contains(nombres) ||
                                            x.ApellidoM.Contains(nombres))
                                            .Select(x => new _Persona
                                            {
                                                Id = x.IDPersona,
                                                Nombres = x.Nombres,
                                                ApellidoP = x.ApellidoP,
                                                ApellidoM = x.ApellidoM,
                                                FechaNacimiento = x.FechaNacimiento
                                            });
        }

Even when _Persona has some other properties I just want to return the properties chosen in the method.

The problem is that when I fill my DataView with results, properties that aren't set they are being displayed and I don't want this, so I manually make these columns not visible.

public void LLenarDataView(IEnumerable<_Persona> personas)
        {
            _listaPersonas.DataSource = personas;
            _listaPersonas.Columns["Sexo"].Visible = false;
            _listaPersonas.Columns["Rfc"].Visible = false;
            _listaPersonas.Columns["Curp"].Visible = false;
            _listaPersonas.Columns["EstadoCivil"].Visible = false;
            _listaPersonas.Columns["Direccion"].Visible = false;
            _listaPersonas.Columns["Cp"].Visible = false;
            _listaPersonas.Columns["Delegacion"].Visible = false;
            _listaPersonas.Columns["Email"].Visible = false;
            _listaPersonas.Columns["Telefono"].Visible = false;
            _listaPersonas.Columns["Celular"].Visible = false;
            _listaPersonas.Columns["Empresa"].Visible = false;
            _listaPersonas.AutoResizeColumns();
        }

Is there a simpler way of doing the same?

Your dataview automatically generates columns based on data from your class. Neat way to hide columns is to use "Browsable" attribute in your class like this:

[Browsable(false)]
public string MyString { get;set;}

See this so post for reference.
