我拿回來，我發現一個shift+click multiple select解決方案的GridView。所有的功勞歸功於mdv在asp論壇上。

var _sPreviousRow = null; 
function wsCheckRange(p_oGridView, p_oControl, e) { 
    var l_sCheckID = p_oControl.id; 
    var l_aCheckIDParts = l_sCheckID.split(p_oGridView.id); 
    var l_sCurrentRow = l_aCheckIDParts[1].split('_')[1].substring(3); 

    var l_oEvent = (window.event) ? event : e; 
    if (l_oEvent.shiftKey) { 
     if (_sPreviousRow != null && _sPreviousRow != l_sCurrentRow) { 
      var l_iFirst = 0, l_iLast = 0; 
      if (parseInt(_sPreviousRow,10) > parseInt(l_sCurrentRow,10)) { 
       l_iFirst = parseInt(l_sCurrentRow,10); 
       l_iLast = parseInt(_sPreviousRow,10); 
      } 
      else { 
       l_iFirst = parseInt(_sPreviousRow,10); 
       l_iLast = parseInt(l_sCurrentRow,10); 
      } 
      for (var i = l_iFirst; i < l_iLast; i++) { 
       var l_sLastRow = (i <= 9 ? '0' + i : i); 
       var l_sCtrlNew = l_sCheckID.replace('ctl' + l_sCurrentRow, 'ctl' + l_sLastRow); 
       var l_oCtrlNew = $get(l_sCtrlNew); 
       if (l_oCtrlNew) { 
        l_oCtrlNew.checked = p_oControl.checked; 
       } 
      } 
     } 
     _sPreviousRow = null; 
    } 
    else { 
     _sPreviousRow = l_sCurrentRow; 
    } 
}
