c# - 以编程方式添加 Boundfield

Question

我对将 BoundFiled 添加到 GridView 有疑问。所有关于 framework .net 2，更高的是不可能的。我有这个代码

BoundField column = new BoundField();
column.HeaderText = "XX";
column.DataField = "ID";
column.SortExpression = "ID";
column.HeaderStyle.CssClass = "titletext";
column.ItemStyle.Width = Unit.Percentage(7);

TableCell tc = new TableCell();
tc.Controls.Add(column);

最后一个命令返回这个错误信息

"The best overloaded method match for 'System.Web.UI.ControlCollection.Add(System.Web.UI.Control)' has some invalid arguments"

这是我在c#中使用的

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

此示例来自网络，无法运行，感谢帮助。

按此添加绑定(bind)列

  BoundField boundField = new BoundField();
  boundField.DataField = "ID";
  boundField.HeaderText = "ID";
  boundField.SortExpression = "ID";
  boundField.HeaderStyle.CssClass = "titletext";
  boundField.ItemStyle.Width = Unit.Percentage(7);
  GridView1.Columns.Add(boundField);
  //bind gridview..

  bindgridview();

 note: data source must contain the ID column
