我用网上给的方法，动态创建模板列，许多功能很实用，就是只能显示一行，其他都是空白

不知到怎么回事
下面是核心代码：

private void GeneralCols()

        {

            // 第1个模板列： Label 

            // HeaderTemplate Row

            System.Collections.Generic.Dictionary<string, ControlField> controlFieldList1 = new System.Collections.Generic.Dictionary<string, ControlField>();

            TemplateField col1 = new TemplateField();

            col1.ShowHeader = true;

            // CheckBox

            System.Web.UI.WebControls.CheckBox chk = new CheckBox();

            chk.ID = "chk";

            //

            System.Collections.Generic.Dictionary<string, string> fields0 = new System.Collections.Generic.Dictionary<string, string>();

            fields0.Add("Checked", "isYes");

            //

            ControlField controlField0 = new ControlField(ControlTypeEnum.CheckBox, chk, fields0);

            controlFieldList1.Add(chk.ID, controlField0);

            //

            MyTmeplateColumn col1_headerow = new MyTmeplateColumn(DataControlRowType.Header, "学生编号", controlFieldList1);

            col1.HeaderTemplate = col1_headerow;



            // ItemTemplate Row

            System.Collections.Generic.Dictionary<string, ControlField> controlFieldList2 = new System.Collections.Generic.Dictionary<string, ControlField>();

            //

            System.Web.UI.WebControls.Label lblID = new Label();

            lblID.ID = "lblID";

            //

            System.Collections.Generic.Dictionary<string, string> fields2 = new System.Collections.Generic.Dictionary<string, string>();

            fields2.Add("Text", "ID");

            //

            ControlField controlField1 = new ControlField(ControlTypeEnum.Label, lblID, fields2);
