            if (page <= 0) 
                page = 1; 
            if (page > PaObj.PageCount) 
                page = PaObj.PageCount; 
            PaObj.CurrentPageIndex = page - 1; 
            this.message.DataSource=PaObj; 
            this.message.DataBind(); 

            this.Page1.Currpage = page; 
            this.Page1.Pagesize = PaObj.PageSize; 
        } 

        protected void OnClick_Mestype(object sender, CommandEventArgs e) { 
            ViewState["mestype"] = Convert.ToByte(); 
            DataBind(); 
        } 

在OnClick_Mestype事件中触发DataBind方法,却更新不了Page1中的属性值...请大家帮助看一下,谢谢了..

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                ViewState["mestype"] = 0;
                DataBind();
            }
        }
在上面可以给Page1属性赋值的
