使用编程方式动态添加DataGrid模板列：

public class UserItemTemplate : ITemplate {
   #region ITemplate 成员

   public void InstantiateIn(Control container) {
    Label lbl = new Label();
    lbl.DataBinding += new EventHandler(lbl_DataBinding);
    container.Controls.Add( lbl );
   }

   #endregion

   private void lbl_DataBinding(object sender, EventArgs e) {
    Label lbl = (Label)sender;
    if( DataBinder.Eval( ((DataGridItem)lbl.NamingContainer).DataItem , "HasPayPoint" ).ToString() == "True" ){
     lbl.Text = DataBinder.Eval( ((DataGridItem)lbl.NamingContainer).DataItem , "UserName" ) + "<img src='" + FC.CMS.Utility.Path.ApplicationFileHttpUrl + "modules/auto/GroupBuy/IsMember.gif' alt='已支付保证金会员'>";                                     
    }  
    else
     lbl.Text = DataBinder.Eval( ((DataGridItem)lbl.NamingContainer).DataItem , "UserName" ).ToString();
   }
  }

...

TemplateColumn col1 = new TemplateColumn();
   col1.HeaderText = "用户名";
   col1.ItemStyle.CssClass = "Normal";
   col1.ItemTemplate = new UserItemTemplate() ;
   UserList.Columns.Add( col1 );
