为gridview的每个单元格添加鼠标悬停提示文本（tooltip）

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs
e)
    {
        for
(int i = 0; i < e.Row.Cells.Count;
i++)//获取总列数
       
{
           
//如果是数据行则添加title
           
if (e.Row.RowType ==DataControlRowType.DataRow
)
           
{//设置title为gridview的head的text
               
e.Row.Cells[i].Attributes.Add("title",
e.Row.Cells[i].Text);
           
}

}
   
}
