最首页前一页下一页最后页

代码：

     private   void  ShowStats()
         {
            //显示当前页面是第几页
            lblCurrentIndex.Text = "第 " + (DataGridPage.CurrentPageIndex + 1).ToString() + " 页";
            //显示总页数
            lblPageCount.Text = "总共 " + DataGridPage.PageCount.ToString() + " 页";
        }

     public   void  PageButtonClick( object  sender, EventArgs e)
         {
            //取得按钮单击时传递的命令参数
            string arg = ((LinkButton)sender).CommandArgument.ToString();
            switch(arg)
            {
                //如果点击的是“下一页”
                case "next":
                    //如果当前页不是最后一页
                    if (DataGridPage.CurrentPageIndex < (DataGridPage.PageCount - 1))
                    {
                        //设置DataGrid控件的当前页索引为下一页面
                        DataGridPage.CurrentPageIndex += 1;
                    }
                    break;
                //如果点击的是“前一页”
                case "prev":
                    //如果当前页不是首页
                    if (DataGridPage.CurrentPageIndex > 0)
                    {
                        //设置DataGrid控件的当前页索引为上一页面
                        DataGridPage.CurrentPageIndex -= 1;
                    }
                    break;
                //如果点击的是“最后页”
                case "last":
                    //设置当前页的索引为最后一页
                    DataGridPage.CurrentPageIndex = (DataGridPage.PageCount - 1);
                    break;
                //默认为”最首页“
                default:
                    //设置当前页的索引为首页
                    DataGridPage.CurrentPageIndex = System.Convert.ToInt32(arg);
                    break;
            }
            BindGrid();
            ShowStats();
        }

         public   void  DataGridPage_Page( object  sender, DataGridPageChangedEventArgs e)
         {
            //设置DataGrid当前页的索引值为用户选择的页的索引
            DataGridPage.CurrentPageIndex = e.NewPageIndex;
            //重新绑定数据
            BindGrid();
            //显示当前分页信息
            ShowStats();
        }

     private   void  InitializeComponent()
         {    
            this.DataGridPage.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.DataGridPage_Page);
            this.DataGridPage.SelectedIndexChanged += new System.EventHandler(this.DataGridPage_SelectedIndexChanged);
            this.Load += new System.EventHandler(this.Page_Load);

        }
