不知道怎么表达..看代码应该明白了.

public partial class operate : System.Web.UI.Page
    {
        private int id = 0;
        private List<Model.Keys> lists = null;
        public operate() { lists = new List<Model.Keys>(); }
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!int.TryParse(Request.QueryString["id"].ToString(), out id))
                id = 0;
            if (!IsPostBack) {
                lists = new SQLserverDAL.KeysDAL().Items(id, false);
                this.list.DataSource = lists;
                this.list.DataBind();
            }
        }

 
        protected void ReMove_Click(object sender, CommandEventArgs e) {
            int id = Convert.ToInt32();
            lists.Remove(new SQLserverDAL.KeysDAL().Item(id));
            this.list.DataSource = lists;
            this.list.DataBind();
        }
    }
}

目点是想实现在ReMove_Click中移除指定的项,但结果是到ReMove_Click中时lists就已经为空了.请问要怎么更改或有其它方法代替..
