在 asp.net 中对网格视图进行排序

Question

private void BindGridView(string field)
    {       
        string userName = field;
        //Get OrganisationID from user Table
        string OrgIdQueryText = "SELECT tbl_organisation_OrganisationID FROM tbl_user WHERE Email ";
        int newOrgID = Convert.ToInt32(server.performQuery(OrgIdQueryText, userName, MySqlDbType.VarChar));

        MySqlCommand command = new MySqlCommand();
        DataSet ds = new DataSet();

        string MysqlStatement = "SELECT MsgID, MsgText, Title, RespondBy, ExpiresBy, OwnerName, Status FROM tbl_message WHERE tbl_user_tbl_organisation_OrganisationID = @Value1";
        using (server)
        {
            MySqlParameter[] param = new MySqlParameter[1];
            param[0] = new MySqlParameter("@value1", MySqlDbType.Int32);
            param[0].Value = newOrgID;
            command.Parameters.AddWithValue("@Value1", newOrgID);
            ds = server.ExecuteQuery(CommandType.Text, MysqlStatement, param);
        }

        Grid_Messagetable.DataSource=ds;
        Grid_Messagetable.DataBind();
}

我正在对网格视图进行数据绑定，它根据 MsgID 显示行。我希望它按降序显示，以便新消息显示在网格顶部

更改您的查询以进行适当的排序，如下所示：

string MysqlStatement = "SELECT MsgID, MsgText, Title, RespondBy, ExpiresBy, OwnerName, Status FROM tbl_message WHERE tbl_user_tbl_organisation_OrganisationID = @Value1 order by MsgID desc";
