DataSet ds = new System.Data.DataSet();
DataTable name; 
DataTable city; 
DialogResult dlg;
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.ActiveSheet.DataSource = ds;  
fpSpread1.ActiveSheet.DataMember = "Customers";
fpSpread1.ActiveSheet.SetColumnWidth(2, 150);
fpSpread1.ActiveSheet.ExpandRow(0, true);
dlg = MessageBox.Show("Do you want to see if the child is visible?", "GetChildVisible", MessageBoxButtons.YesNo);
if (dlg == DialogResult.Yes)
{
    bool b;
    FarPoint.Win.Spread.SheetView sv;
    sv = fpSpread1.ActiveSheet.GetChildView(1, 0);
    b = fpSpread1.ActiveSheet.GetChildVisible(sv);
    label1.Text = b.ToString();
}
