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", 0 });
            dtParent.Rows.Add(new object[] { "Parent2", 1 });

            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", 0 });
            dtChild.Rows.Add(new object[] { "Child1-2", 0 });
            dtChild.Rows.Add(new object[] { "Child1-3", 0 });
            dtChild.Rows.Add(new object[] { "Child2-1", 1 });
            dtChild.Rows.Add(new object[] { "Child2-2", 1 });
            dtChild.Rows.Add(new object[] { "Child2-3", 1 });
            
            ds.Relations.Add("Relation1", dtParent.Columns["Column2"], dtChild.Columns["Column2"]);
            
            fpSpread1.ActiveSheet.DataSource = ds;

            fpSpread1_Sheet1.Columns[1].Visible = false;
            for (int i = 0; i < fpSpread1_Sheet1.Rows.Count; i++)
            {
                fpSpread1_Sheet1.GetChildView(i, 0).Columns[1].Visible = false;
            }
        }
