                CreateControl();
                IsNull();
            }
        }

        //下一頁的單擊事件
        private void DownLb_Click(object sender, EventArgs e)
        {
            if (CurrentPageIndex < PageCount)
            {
                CurrentPage.Session["index"] = ++CurrentPageIndex;
                CreateControl();
                IsNull(); 
            }
        }

        private void DUpLb_Click(object sender, EventArgs e)
        {
            int pi = (CurrentPageIndex-10) / 10 * 10;
            CurrentPage.Session["index"] = pi;
            IsNull();
        }

        private void DDownLb_Click(object sender, EventArgs e)
        {
            int pi = (CurrentPageIndex + 10) / 10 * 10;
            CurrentPage.Session["index"] = pi;
            IsNull();
        }

    }
}      

使用方法

SplitPage sp = new SplitPage(this);
            sp.GetListHandle += bm.GetBooks;//分頁查詢資料庫的方法
            sp.PageCount = bm.BooksCount() / sp.PageSize ;//總頁數
            this.divOne.Controls.Add(sp.BindGridView(dvBookInfo));//把放回的div加入到設定好的divOne中，dvBookInfo是一個GridView控件，
//也可以是Repeater控件      

上面這個分頁類可以在類中添加相關代碼，支援其他ASP.NET伺服器控件綁定資料後的分頁

備注：菜鳥，求指點。
