效果如下图所示:

实现原理:

     为DataGrid中的每一行,绑定onmouseover、onmousemove、onmouseout事件,使的鼠标移动到行内时,自动显示一个<div>,鼠标移出该行,就把这个<div>隐藏掉。

实现代码:

     前台:

1.   定义<div>的样式:

<style type="text/css">

.transparent { FILTER: alpha(opacity=85);

BORDER-TOP: indianred 1px solid;

BORDER-RIGHT: indianred 1px solid; 

BORDER-LEFT: indianred 1px solid;

BORDER-BOTTOM: indianred 1px solid;

POSITION: absolute;

BACKGROUND-COLOR: infobackground;

DISPLAY: none  }

</style>

2.   显示和隐藏窗体的脚本:

<script language="javascript">

     //显示弹出窗体

     function Show(Country, City, Address, PostalCode, Phone, Fax)

     {

         document.getElementById("td1").innerText="国家:"+Country;

         document.getElementById("td2").innerText="城市:"+City;

         document.getElementById("td3").innerText="地址:"+Address;

         document.getElementById("td4").innerText="邮政编码:"+PostalCode;

         document.getElementById("td5").innerText="电话:"+Phone;

         document.getElementById("td6").innerText="传真:"+Fax;

         //获得鼠标的X轴的坐标

         x = event.clientX + document.body.scrollLeft;

         //获得鼠标的Y轴的坐标

         y = event.clientY + document.body.scrollTop + 20;

         //显示弹出窗体

         Popup.style.display="block";

         //设置窗体的X,Y轴的坐标

         Popup.style.left = x;

         Popup.style.top = y;

     }

//隐藏弹出窗体

function Hide()

     {

         //隐藏窗体

         Popup.style.display="none";

     }

</script>

3.   ToolTip窗体的代码

<div id="Popup" class="transparent" style=" Z-INDEX: 200">

     <table border="0" cellpadding="0" style="FONT-SIZE: x-small">

          <tr>

<td align="middle" bgcolor="indianred"><font color="white">联系方式</font></td>

</tr>

         <tr><td id="td1"></td></tr>

         <tr><td id="td2"></td></tr>

         <tr><td id="td3"></td></tr>

         <tr><td id="td4"></td></tr>

         <tr><td id="td5"></td></tr>

         <tr><td id="td6"></td></tr>

     </table>

</div>

     后台:

private DataTable dt;

private void Page_Load(object sender, System.EventArgs e)

{

     // Put user code to initialize the page here

     if(!IsPostBack)

     {

          SqlConnection cnn = new SqlConnection();
