    System.Data.DataSet ds = new System.Data.DataSet();
    DataTable name; 
    DataTable city; 
    name = ds.Tables.Add("Customers"); 
    name.Columns.AddRange(new DataColumn[] {new DataColumn("LastName", typeof(string)), new DataColumn("FirstName", typeof(string)),
    new DataColumn("ID", typeof(Int32))}); 
    name.Rows.Add(new object[] {"Fielding", "William", 0}); 
    name.Rows.Add(new object[] {"Williams", "Arthur", 1}); 
    name.Rows.Add(new object[] {"Zuchini", "Theodore", 2}); 
    city = ds.Tables.Add("City/State"); 
    city.Columns.AddRange(new DataColumn[] {new DataColumn("City", typeof(string)), new DataColumn("Owner", typeof(Int32)), new
    DataColumn("State", typeof(string))}); 
    city.Rows.Add(new object[] {"Atlanta", 0, "Georgia"}); 
    city.Rows.Add(new object[] {"Boston", 1, "Mass."}); 
    city.Rows.Add(new object[] {"Tampa", 2, "Fla."}); 
    ds.Relations.Add("City/State", name.Columns["ID"], city.Columns["Owner"]); 
    fpSpread1.DataSource = ds;
    fpSpread1.DataMember = "Customers";
    Label1.Text = "Click on one of the + next to a row to fire the event";
    
    private void fpSpread1_ChildViewCreated(object sender, FarPoint.Win.Spread.ChildViewCreatedEventArgs e)
    {
         ListBox1.Items.Add("ChildViewCreated event fired!");
    }

    FpSpread1.DataMember = "Customers"
    Label1.Text = "Click on one of the + next to a row to fire the event"
