使用CompontDesigner即可。并重写其中的Initialize方法

例如

using System;

using System.ComponentModel;

using System.ComponentModel.Design;

using System.Web.UI;

using System.Web.UI;

namespace aaa

{

     public class WebTimer2Designer:ComponentDesigner

    {

          public override void Initialize(IComponent component)

          {

                IContainer contailer = component.Site.Container;

                foreach(IComponent comp in Container.Components)

                {

                    if(comp is Page)

                           ((WebTimer2)component)._Page = (Page)comp;

                }

               base.Initailze(component);

          }

    }

}
