来源：互联网发布：2010人口普查全国数据编辑：程序博客网时间：2024/05/29 15:57

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：

.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：

//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

<tr>

</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();

cnn.ConnectionString = "data source=localhost;initial catalog=Northwind;password=;"

+"persist security info=True;user id=sa;workstation id=APJ062;packet size=4096";

string sqlstr = "select Top 16 CustomerID, CompanyName, ContactTitle,Country, City, Address,PostalCode,Phone,Fax from Customers";

cnn.Open();

SqlDataAdapter ad = new SqlDataAdapter(sqlstr,cnn);

dt = new DataTable();

ad.Fill(dt);

grdCustomer.DataSource = dt;

grdCustomer.DataBind();

}

private void grdCustomer_ItemDataBound(object sender,

System.Web.UI.WebControls.DataGridItemEventArgs e)

{

if(e.Item.ItemType == ListItemType.AlternatingItem

|| e.Item.ItemType == ListItemType.Item)

{

e.Item.Attributes.Add("onmouseover",

"this.oldcolor=this.style.backgroundColor;this.style.backgroundColor='#C8F7FF';");

e.Item.Attributes.Add("onmousemove",
