用代码为GridVeiw添加模板列

#创建一个ItemTemplate：
　由于ItemTemplate是继承于ITemplate接口的，所有必须实现ITemplate接口中的InstantiateIn方法。
     
    private class DeletItem :ITemplate
    {
        #region ITemplate 成员

        void ITemplate.InstantiateIn(Control container)
        {
            ImageButton ib       = new ImageButton();
            //指定绑定数据字段
            ib.DataBinding     += new EventHandler(ib_DataBinding);
            ib.CommandName = "Del";
            ib.ImageUrl            = "~/Images/icon-delete.gif";
            ib.ToolTip              = "删除";
            container.Controls.Add(ib);
        }            
        void ib_DataBinding(object sender, EventArgs e)
        {
            ImageButton ib            = (ImageButton)sender;
            GridViewRow di         = (GridViewRow)ib.NamingContainer;
            ib.CommandArgument = ((DataRowView)di.DataItem)["id"].ToString();
        }
        #endregion
    }

＃在代码中运用DeleteItem列

            TemplateField  tpd = new TemplateField();
            tpd.HeaderText     = "删除";
            tpd.ItemTemplate  = new DeletItem();
            GridView1.Columns.Add(tpd);
