关于Button 动态生成MenuCheckBox点击回发

咕噜

您好：我想请问一下Button控件后台生成MenuCheckBox后，如何添加CheckedChange事件，我这边

mcb.CheckedChanged += new EventHandler<CheckedEventArgs>(mcb_CheckedChanged);

这样添加点击无效果。

MenuCheckBox mcb = new MenuCheckBox();
mcb.ID = obj.SiteValue.ToString();
mcb.Text = obj.SiteName.ToString();
mcb.AutoPostBack = true;
mcb.CheckedChanged += new EventHandler<CheckedEventArgs>(mcb_CheckedChanged);
btnSelectSite.Menu.Items.Add(mcb);
