推荐答案

如果不起作用通过分配html代码，尝试在代码隐藏文件中的RowDataBound事件中分配tooltip属性。检查下面的代码 -

If it does not work by assigning in html code, try to assign tooltip property in RowDataBound event in code behind file. Check the code below-

protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    ImageButton lbtnSendMail = (ImageButton)e.Row.FindControl("lbtnSendMail");
    lbtnSendMail.ToolTip = "Send Mail";

    ImageButton ibtnDelete = (ImageButton)e.Row.FindControl("ibtnDelete");
    ibtnDelete.ToolTip = "Delete";
}

尝试使用ToolTip指定AlternateText属性。 ToolTip不适用于所有浏览器。

Try specifying AlternateText property along with ToolTip. ToolTip does not work on all browsers.
