データ テーブルのビューを含む DataView オブジェクト
次のサンプルコードでは、このメンバを使用して、データビュー内のリレーションの親テーブルを返しています。
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.ActiveSheet.DataSource = ds;  
fpSpread1.ActiveSheet.DataMember = "Customers";
fpSpread1.ActiveSheet.SetColumnWidth(2, 150);
fpSpread1.ActiveSheet.ExpandRow(0, true);
label1.Text = "The parent table of the data relation for the sheet is - " + fpSpread1.ActiveSheet.GetDataView(false).DataViewManager.DataSet.Relations["City/State"].ParentTable.ToString();
Dim ds As New System.Data.DataSet()
Dim name As DataTable
Dim city As DataTable
name = ds.Tables.Add("Customers")
name.Columns.AddRange(New DataColumn() {New DataColumn("LastName", Type.GetType("System.String")), New DataColumn("FirstName",
Type.GetType("System.String")), New DataColumn("ID", Type.GetType("System.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", Type.GetType("System.String")), New DataColumn("Owner", Type.GetType("System.Int32")),
New DataColumn("State", Type.GetType("System.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."})

FpSpread1.ActiveSheet.DataSource = ds
FpSpread1.ActiveSheet.DataMember = "Customers"
FpSpread1.ActiveSheet.SetColumnWidth(2, 150)
FpSpread1.ActiveSheet.ExpandRow(0, True)
Label1.Text = "The parent table of the data relation for the sheet is - " & FpSpread1.ActiveSheet.GetDataView(False).DataViewManager.DataSet.Relations("City/State").ParentTable.ToString()
