Good afternoon, I'm filling a datagriview with a list whose entity is:

public class ECliente
{
    public int CLI_CODIGO { get; set; }
    public string CLI_NOMBRE { get; set; }
    public string CLI_RUC { get; set; }
    public string CLI_DIRECCION { get; set; }
    ...
    ...
    public int EJE_CODIGO_AM { get; set; }
    public int TP_CODIGO { get; set; }

    public ECiudad CIUDAD { get; set; }

}

and the entity ECcity is as follows

public class ECiudad
{
    public int CIU_CODIGO { get; set; }
    public string CIU_NOMBRE { get; set; }
    public string CIU_ESTADO { get; set; }
    public string CIU_RUBRO_CON { get; set; }
}

and in the business layer I have the filling of my list.

    public List<ECliente> GetListClientes(string Criterio)
    {
        List<ECliente> lista = new List<ECliente>();
        ....
        ....

}

In the form I have a toolStrip button whose event is:

    private void tsBuscar_Click(object sender, EventArgs e)
    {
         ...
        dgvLista.AutoGenerateColumns = true;
        dgvLista.DataSource = nCliente.GetListClientes(sb.ToString());
    }

and I filled the datagridview

I want the CIU_NOMBRE property value of the entity ECIUDAD to be displayed ??

Also, I can use EF6 with SQL Server 2000 Express Edition ????, since all entities are creating it manually ...

Thanks for your kind help and suggestions.

overwrite the .ToString () function in the secondary class by returning the property you want and you'll have it fixed.

It would be something like this:

public class ECiudad
{
    public int CIU_CODIGO { get; set; }
    public string CIU_NOMBRE { get; set; }
    public string CIU_ESTADO { get; set; }
    public string CIU_RUBRO_CON { get; set; }
    public override string ToString()
    {
        return CIU_NOMBRE;
    }
}
