GridView绑定时通过RowDataBound事件获取数据源列值

/// <summary>
/// 当数据绑定时， 设置未读邮件加粗显示
/// </summary>
protected void gvData_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //if (DataBinder.Eval(e.Row.NamingContainer, "DataRow.Readed").ToString() == "0")
    //if (gvData.DataKeys[e.Row.RowIndex][1].ToString() == "0")

    DataRowView drv = (DataRowView)e.Row.DataItem;
    if (drv != null)
    {
        if (drv.Row["Readed"].ToString() == "0")
            e.Row.Style["font-weight"] = "bold";
    }
}

要引入命名空间：

using System.Data;
