在後臺的GridView1_RowDataBound()方法添加代碼，最後代碼如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
int i;
//執行循環，保證每條數據都可以更新
for (i = 0; i < GridView1.Rows.Count; i++)//這裏如果i從0開始的話，那麼鼠標移動到數據行的第一行時，顏色並沒有改變，所以建議改爲 i = -1
{
//首先判斷是否是數據行
if (e.Row.RowType == DataControlRowType.DataRow)
{
//當鼠標停留時更改背景色
e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
//當鼠標移開時還原背景色
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
}
}
}
