This might help to get started:
这可能有助于开始：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
var linkField = new TemplateField();
linkField.ItemTemplate = new LinkColumn();
GridView1.Columns.Add(linkField);
}
}
class LinkColumn : ITemplate
{
public void InstantiateIn(System.Web.UI.Control container)
{
LinkButton link = new LinkButton();
link.ID = "linkmodel";
container.Controls.Add(link);
}
}

但是：
Although you can dynamically add fields to a data-bound control, it is strongly recommendedthat fields be statically declared and then shown or hidden, as appropriate. Statically declaring all your fields reduces the size of the view state for the parent data-bound control.
尽管您可以向数据绑定控件动态添加字段，但 强烈建议静态声明字段，然后根据需要显示或隐藏字段。静态声明所有字段会减少父数据绑定控件的视图状态的大小。
