GridView高效分页和搜索功能的实现代码(6)

protected void btnReset_Click(object sender, EventArgs e)
     (
         RecordsCount = GetRecordsCount("default");//默认信息总数
         PagesCount = RecordsCount / PAGESIZE + OverPage();//默认的页总数
         ViewState["PagesCount"] = RecordsCount / PAGESIZE - ModPage();//保存末页索引，比页总数小1
         ViewState["PageIndex"] = 0;//保存页面初始索引从0开始
         ViewState["JumpPages"] = PagesCount;
         //保存页总数，跳页时判断用户输入数是否超出页码范围
         //显示lbPageCount、lbRecordCount的状态
         lbPageCount.Text = PagesCount.ToString();
         lbRecordCount.Text = RecordsCount.ToString();
         //判断跳页文本框失效
         if (RecordsCount <= 10)
         {
             GotoPage.Enabled = false;
         }
             GridViewDataBind("default");//调用数据绑定函数TDataBind()进行数据绑定运算
     }

这里的高效分页方法主要用的是select top 10 Id ，Name from tb where Id not in (select top 10*N from tb order by Id asc) order by Id asc
