在ASP.NET的DataGrid中，鼠标点击某行进行高亮显示的解决方案

首先在页面端加入如下Javascript代码：
----------------------------------------------

< SCRIPT language = " javascript " >
         <!--
             var  oldid = "" ;
             var  selid = "" ;
             function  onfocuscolor(line, eventid)
             {
                if (oldid == line){
                    line.style.backgroundColor = "#ffffff";
                    line.style.color = "#003399";
                    oldid = "";
                    selid = "";
                }
                else{
                    if (oldid==""){
                        line.style.backgroundColor = "#009999";
                        line.style.color = "#CCFF99";
                        oldid = line;
                        selid = eventid;
                    }
                    else{
                        line.style.backgroundColor = "#009999";
                        line.style.color = "#CCFF99";
                        oldid.style.backgroundColor = "#ffffff";    
                        oldid.style.color = "#003399";
                        oldid = line;
                        selid = eventid;
                    }
                }
            }
         -->
         </ SCRIPT >

然后在后台代码端的 ItemDataBound 事件函数中，加入事件代码：
---------------------------------------------------------------------

if  ((e.Item.ItemType != ListItemType.Header) && (e.Item.ItemType != ListItemType.Footer))
             {
                     e.Item.Attributes.Add("onMousedown", "javascript:onfocuscolor(this,'" + e.Item.Cells[1].Text + "')");
            }

 搞定！

不过，有一个遗留问题，如何让Server端知道Client端现在鼠标点击的是哪一行？

有大侠知道吗？请留言，谢谢！
