调用代码：int intStart, intEnd, intRows;//intRows返回查询数据集合的总记录数量
intRows = 0;
//设置其实记录位置
intStart = CtrlPag.PageIndex * CtrlPag.PageSize; //获取SQLRead的开始记录
intEnd = CtrlPag.PageSize;                       //获取记录条数量
DataTable dtb;  //获取查询记录的总记录数
CtrlPag.TotalRecords = intRows;//给控件设置总记录数
GrideView.PageSize = CtrlPag.PageSize; //为GrideView设置当前页显示记录条数
//下面就不用解释了哦
GrideView.DataSource = dtb;
GrideView.DataBind();
