gridview 动态添加列，网上搜的不错的代码，可以借鉴下

C# code public partial class ManagementSystem_Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { GridView1.DataSource = BuildGridViewDataSource(); GridView1.DataBind(); } ///

/// 用来做例子中的数据源 ///

/// private DataTable BuildGridViewDataSource() { DataTable dt = new DataTable(); dt.Columns.Add("Number"); dt.Columns.Add("Name"); DataRow dr = dt.NewRow(); dr["Number"] = "1000"; dr["Name"] = "张三"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["Number"] = "1001"; dr["Name"] = "李四"; dt.Rows.Add(dr); return dt; } protected void Button1_Click(object sender, EventArgs e) { BoundField nameColumn = new BoundField(); nameColumn.HeaderText = "姓名"; nameColumn.DataField = "Name"; GridView1.Columns.Add(nameColumn); GridView1.DataSource = BuildGridViewDataSource(); GridView1.DataBind(); } } HTML code
