用JavaScript对GridView进行上移下移，保存排序

        //移动排序
        function Move(part)
        {
          var count= document.getElementById('HidCount').value;
          var temp=0;
          var index=0;
          var indexid=0
          for( i=0 ;i<=count;i++)
          {
            var bc=document.getElementById('GVLesson_Row_'+i).style.backgroundColor;
             if(bc=='#f8e0e0')
            { 
                index=document.getElementById('GVLesson_Row_'+i).rowIndex;
                indexid=i;
                //alert("GoUp  "+index);
                temp=temp+1;
            }          
          }
          if(temp<0||temp>1)
          {
            alert("只能选择一节课程！");
            return;
