动态显示图片，并为hyperlink 做鼠标悬停效果

最近在给交通局忙一套好大的系统，到底有多大 ，呵呵 我也不知道，只是知道公司目前报价27万9 。第一次接这样大的活，并且从调研、到开发，都由我一个人主持 。呵呵 压力好大。经过了4个多月的调研，这套系统终于开始投入开发，准备在8月底，软件初步完成，交交通局试用。记录下，记录下在这套系统开中遇到的问题，以及解决方法，供自己和大家参考！
下面是一个遇到的小问题，动态显示图片，并动态添加鼠标悬停效果
代码如下：

< table cellSpacing = " 0 "  cellPadding = " 0 "  width = " 200 "  border = " 0 " >
                             < tr >
                                 < td  class = " biance "  style = " WIDTH: 87px " ></ td >
                                 < td valign = " top "   >
                                     < asp:repeater id = " Repeater1 "  runat = " server " >
                                         < ItemTemplate >
                                             < table width = " 200 "  border = " 0 "  cellspacing = " 0 "  cellpadding = " 0 " >
                                                 < tr >
                                                     < td background = " images/bg.jpg "   class = " biance " >< script language = " javascript " >
document.write( " <img src="images/<%# DataBinder.Eval(Container,  " DataItem.ID " ) %>.jpg"> " );
                                                         </ script >
                                                   < asp:HyperLink id = HyperLink1 Text = ' <%# DataBinder.Eval(Container.DataItem, "biance") %> '  NavigateUrl = ' <%# "detailspage.aspx?id=" + HttpUtility.UrlEncode(DataBinder.Eval(Container.DataItem,"ID").ToString()) %> '  ToolTip = ' <%#   DataBinder.Eval(Container.DataItem,"title")   %> '  runat = " server "   />            </ td >
                                                 </ tr >
                                             </ table >
                                         </ ItemTemplate >
                                     </ asp:repeater ></ td >
                             </ tr >
                         </ table >
                     </ td >
                     < td width = " 79% " >& nbsp; </ td >
                 </ tr >
             </ table >

cs文件代码如下：

     private   void  Page_Load( object  sender, System.EventArgs e)
         ... {
            // 在此处放置用户代码以初始化页面
            BindData();

        }
         private   void  BindData()
         ... {
            TAJTJ.Components.SaftTrain st=new SaftTrain();
            Repeater1.DataSource = st.GetBookNo();
            Repeater1.DataBind();
        }
 saftTrain代码如下
... #region 
        //读取培训教程
        public SqlDataReader GetBookNo()
        ...{
            Database data = new Database();
            SqlDataReader dr = null;
            SqlParameter[] prams = ...{};
            data.RunProc ("GetBookNo",prams,out dr);
            return(dr);        
        }
#endregion
