asp.net AspNetPager Repeater PagedDataSource 假分页方法适用于小数据量分页

 string sqlString = String.Format("SELECT * FROM V_XSOA_OASEARCH WHERE BT LIKE '%{0}%'",searchName);

            DataTable dt = BP.DA.DBAccess.RunSQLReturnTable(sqlString);

            this.AspNetPager1.RecordCount = dt.Rows.Count;//绑定总数量

            this.AspNetPager1.AlwaysShow = true;

            //先声明一个分页类对象

            PagedDataSource ps = new PagedDataSource();

            ps.AllowPaging = true;

            ps.PageSize = this.AspNetPager1.PageSize;

            ps.CurrentPageIndex = this.AspNetPager1.CurrentPageIndex - 1;

            ps.DataSource = dt.DefaultView;

            this.rp_sarch.DataSource = ps;

            this.rp_sarch.DataBind();
