1: lblTotalPage.Text = (Math.Ceiling(((double)dsVisitRecords.Tables[0].Rows.Count / VisitRecords.PageSize))).ToString();
2: //Ceiling是無條件進位的意思
3: lblCurrentPage.Text = "1";
4: //顯示第一頁，在每個按鈕處都要寫以reset不然上次按的頁數會保留
5: //若要換頁寫：lblCurrentPage.Text = (e.NewPageIndex + 1).ToString();，頁數會加1的意思
6: lblTotalNumber.Text = dsVisitRecords.Tables[0].Rows.Count.ToString();
ps. 第5行的e是指按鈕的PageIndexChanging
