如何给Asp.Net表格或控件加上自定义的提示框？

aspx页面:

<a href=# onClick='Play("<%#DataBinder.Eval(Container.DataItem,"mid")%>");return false;'
           onmouseover='showTip2(this, popTip, "歌曲名：<%#DataBinder.Eval(Container.DataItem,"mname") %>"
                   +"<br>所属专辑：<%#DataBinder.Eval(Container.DataItem,"cname") %>"
                   +"<br>演唱者：<%#DataBinder.Eval(Container.DataItem,"msinger") %>"
                   +"<br>点击数：<%#DataBinder.Eval(Container.DataItem,"mhits") %>"
                   +"&nbsp;|&nbsp;<%#DataBinder.Eval(Container.DataItem,"mstar") %>星级"
                   +"<br>添加人：<%#DataBinder.Eval(Container.DataItem,"uname") %>"
                   +"<br>添加时间：<%#DataBinder.Eval(Container.DataItem,"mtime") %>")'
           onmouseout="hideTip(this, popTip, event)">
