排序不变 [英] Sorting does not change

问题描述

你好

我在WPF应用程序中具有ListView，其中显示了所有播放器，

 i've ListView in WPF Application which display all Players ,

按游戏名称和

排序方式:得分降序

            PlayersList.ItemsSource = myList;  
            CollectionView view = (CollectionView)CollectionViewSource.GetDefaultView(PlayersList.ItemsSource);
            PropertyGroupDescription groupDescription = new PropertyGroupDescription("Game");
            SortDescription sd = new SortDescription("Score", ListSortDirection.Descending);
            view.SortDescriptions.Add(sd);
            view.GroupDescriptions.Add(groupDescription);

当我更新特定用户的分数时，它工作正常

it works fine , when i am updating  the score of specific user

ScoreHistory param = myList.FirstOrDefault(z => z.Player == userName );
                    if (param != null)
                    {
                        param.Score = newscore;
                         
                    }

分数得到了很好的更新，但是分数的排序或排名没有变化.

The score is well updated but the sorting or the ranking of scores does not change.

public class ScoreHistory : INotifyPropertyChanged
    {
     private string _player;
    public string Player
    {
        get { return _player; }
        set
        {
            if (_player != value)
            {
                _player = value;
                OnPropertyChanged("Player");
            }
        }
    } 
	
	
	
    private int _score;
    public int Score
    {
        get { return _score; }
        set
        {
            if (_score != value)
            {
                _score = value;
                OnPropertyChanged("Score");
            }
        }
    }
     

   
        private string _game;
        public string Game
        {
            get { return _game; }
            set
            {
                if (_game != value)
                {
                    _game = value;
                    OnPropertyChanged("Game");
                }
            }
        }
       


         
    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string p_strPropertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(p_strPropertyName));
    }


}

请帮助我，我的代码有什么问题?

推荐答案

您是否尝试过在 view 上调用 Refesh()方法> 变量?

Have you tried calling the Refesh() method on view variable ?
