ASP.net 用CSS 来隐藏 GridView 的列

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ((TextBox)e.Row.Cells[0].FindControl("TextBox3")).Attributes.Add("onkeyup", "javascript:sumsy(this);");
            e.Row.Cells[13].Style.Add("display", "none");  //隐藏数据列
            e.Row.Cells[14].Style.Add("display", "none");
        }
        else
        {
            e.Row.Cells[13].Style.Add("display", "none");  //隐藏表头
            e.Row.Cells[14].Style.Add("display", "none");
        }
    }
