FarPoint Spread ChildView子视图

有一种需求场景在很多地方都会用到，就是父子关系（头表和子表的关系），比如订单和订单明细。

做过winform的朋友第spread控件应该比较熟悉，或者了解。他的展示方式就通过一个关联关系就可以了，下面是关键代码：

         private void Form1_Load(object sender, EventArgs e)
         {
             DataSet ds = new DataSet();

             var dtParent = ds.Tables.Add("SAMPLE");
             dtParent.Columns.AddRange(new DataColumn[] { new DataColumn("Column1", typeof(string)) {Caption = "父节点"}, new DataColumn("Column2", typeof(int)) });
             dtParent.Rows.Add(new object[] { "Parent1",  });
             dtParent.Rows.Add(new object[] { "Parent2",  });

             var dtChild = ds.Tables.Add("Child1");
             dtChild.Columns.AddRange(new DataColumn[] {new DataColumn("Column1", typeof(string)) {Caption = "子节点"}, new DataColumn("Column2", typeof(int))});
             dtChild.Rows.Add(new object[] { "Child1-1",  });
             dtChild.Rows.Add(new object[] { "Child1-2",  });
             dtChild.Rows.Add(new object[] { "Child1-3",  });
             dtChild.Rows.Add(new object[] { "Child2-1",  });
             dtChild.Rows.Add(new object[] { "Child2-2",  });
             dtChild.Rows.Add(new object[] { "Child2-3",  });

             ds.Relations.Add("Relation1", dtParent.Columns["Column2"], dtChild.Columns["Column2"]);

             fpSpread1.ActiveSheet.DataSource = ds;

             fpSpread1_Sheet1.Columns[].Visible = false;
             for (int i = ; i < fpSpread1_Sheet1.Rows.Count; i++)
             {
                 fpSpread1_Sheet1.GetChildView(i, ).Columns[].Visible = false;
             }
         }
