C# 未从数据库asp.net中删除项目

我正在使用实体框架来填充网格，但我正在尝试删除该项，但没有错误，只是没有任何操作

我的网格如下所示，不知道问题是什么，因为我使用的是类型播放器，所以它应该被删除

我没有这方面的任何进展。有人能帮我一下吗

我猜你错过了一个命令。查看此控件的文档

你为什么要使用GUID？为什么不使用主键或像唯一值这样的简单标识类型？GUID是问题所在，请按原样使用ID。您要删除的项目是否是另一个表的外键？如果该项是另一个表中的外键，SQL将停止您。一支球队可以有很多球员，但球员不是外键self@Timmy如上所述，一个球员可以在一个团队中，即一个团队可以有很多球员，但可以退出that@TranscendentGuid不是问题所在，它是一个unqiue值！不，我没有丢失它。请查看代码并理解我在item命令上手动调用delete object

     public player GetPlayerBYID(Guid _playerId)
        {
            try
            {
                if (_playerId == Guid.Empty)
                {
                    player _player = new player();
                    _player.player_id = "16-56-232";
                    return _player;
                }
                else
                {
                    var q = SoccerEntities.players.Where(p => p.id == _playerId);

                    if (q == null)
                        throw new EntityContextException(string.Format("A player could not be found {0}!", _playerId));
                    else
                        return q.ToList()[0];
                }
            }
            catch (Exception ex)
            {
                throw new EntityContextException("GetPlayerBYID failed.", ex);
            }
        }
