如何在asp.net中用c＃在車輛跟蹤系統中生成停工報告

Question

嗨我正在研究項目車輛跟蹤系統我想生成停工報告它工作正常與PHP和EXTJS，但現在正在改變項目爲ASP .net與C＃。我有4個不同的查詢來顯示報告，但在asp.net gridview我如何綁定所有4個不同的查詢顯示在GridView與分頁。

這是我的PHP代碼

$NewID = ""; 
     $OldID = "";   
     //echo("Select gps_id,lat,lon,tdate,ttime,tdate_time,speed,lname from gps_data where vehicle_no = '$vno' and (CONVERT(tdate_time, DATETIME) between '$FromDate' and '$ToDate') and speed > 1 order by gps_id asc"); 

    $sql1 = mysql_query("Select gps_id,latitude,longtitude,get_date,get_time,get_date_time,speed,location from gps_data where device_id = '$device_id' and host_name = '". $host ."' and (CONVERT(get_date_time, DATETIME) between '$FromDate' and '$ToDate') and speed > 1 order by gps_id asc"); 
    while($row = mysql_fetch_row($sql1)) 
    { 

     $NewID = $row[0]; 
     //echo($OldID); 
     if($OldID > 0) 
     { 
     // echo("Select CONVERT(tdate_time, DATETIME) from gps_data where gps_id = ". $OldID .""); 
      $query = mysql_query("Select get_date_time,date_time from gps_data where gps_id = ". $OldID ." and host_name = '". $host ."'"); 

      if($result = mysql_fetch_row($query)) 
      { 
       $show_old_get_date_time = $result[0]; 
       $old_get_date_time = $result[1]; 
       //echo($old_get_date_time); 
      } 

      $query1 = mysql_query("Select get_date_time,date_time from gps_data where gps_id = ". $NewID ." and host_name = '". $host ."'"); 
      if($result1 = mysql_fetch_row($query1)) 
      { 
        $show_new_get_date_time = $result1[0]; 
        $new_get_date_time  = $result1[1]; 
      } 

     //echo("Select gps_id,lat,lon,tdate,ttime,tdate_time,speed,lname from gps_data where vehicle_no = '$vno' and gps_id > ". $OldID ." and gps_id < ". $NewID ." and (CONVERT(tdate_time, DATETIME) between '$FromDate' and '$ToDate') order by gps_id asc"); 
      $sql2 = mysql_query("Select gps_id,latitude,longtitude,get_date,get_time,get_date_time,speed,location from gps_data where device_id = '$device_id' and host_name = '". $host ."' and gps_id > ". $OldID ." and gps_id < ". $NewID ." and (CONVERT(get_date_time, DATETIME) between '$FromDate' and '$ToDate') order by gps_id asc"); 
      if($rowA = mysql_fetch_row($sql2)) 
      { 

       $NewLoc = parseD($rowA[7]); 
       //echo("SELECT TIMEDIFF('". $new_get_date_time ."','". $old_get_date_time ."')"); 
       $sql3 = mysql_query("SELECT TIMEDIFF('". $new_get_date_time ."','". $old_get_date_time ."')"); 
        if($rowB = mysql_fetch_row($sql3)) 
        { 

          $cnt = $cnt + 1; 
          $DTDiff = $rowB[0]; 

          $strBld .= $comm."{slno:\"". $cnt ."\",get_date:\"". $rowA[3] ."\",get_date_time:\"". $show_old_get_date_time." "."-"." ". $show_new_get_date_time ."\",stoppedTm:\"". $DTDiff ."\",loc_name:\"". $NewLoc ."\",latitude:\"".$rowA[1]."\",longitude:\"".$rowA[2]."\"}"; 
          $comm = ","; 

        } 


      } //while($rowA = mysql_fetch_row($sql2)) 


     } //if($OldID > 0) 

     $OldID = $row[0]; 
     //echo($OldID); 
    } //while($row = mysql_fetch_row($sql1))

分頁是用來顯示剩餘的數據。但似乎你有不同的情況。你可以寫你查詢這些情況，然後將它們聯合起來，並將此查詢綁定爲gridview的數據源。或者你可以設置按鈕或任何其他ui控件爲每個案件更改gridview的數據源。
