这里一的的ObservableCollection的所有财产DataGrid的照片前我添加行：

这里与行DataGrid的照片说：

你可以看到，列添加到DataGrid

XAML的看法：

视图模型：

public EntreeDeCommandeViewModel(IBanniereService banniereService 
      , IItemsFactureService itemsFactureService 
      , IFactureService factureService, INavigationService navigationService) 
     { 
      _banniereService = banniereService; 
      _navigationService = navigationService; 
      _itemsFactureService = itemsFactureService; 
      _factureService = factureService; 
      RetrieveArgs = new RetrieveArticleFactureArgs(); 

       AjouterItem = new RelayCommand(() => 
       { 
        List<ItemsFacture> _itFacture = new List<ItemsFacture>(); 
        _itFacture.Add(new ItemsFacture() {NombreArticle = RetrieveArgs.NombreArticle 
         , PrixUnitaireArticle = RetrieveArgs.PrixArticle 
         , PrixTotalArticle = (RetrieveArgs.NombreArticle * RetrieveArgs.PrixArticle) }); 
        ItemsFactures = new ObservableCollection<ItemsFacture>(_itFacture); 
       }); 
     } 

     public RetrieveArticleFactureArgs RetrieveArgs {get; set;} 

     private ObservableCollection<ItemsFacture> _itemsFacture; 

     public ObservableCollection<ItemsFacture> ItemsFactures 
     { 
      get 
      { 
       return _itemsFacture; 
      } 

      set 
      { 
       if (_itemsFacture == value) 
       { 
        return; 
       } 

       RaisePropertyChanging(); 
       _itemsFacture = value; 
       RaisePropertyChanged(); 
      } 
     }

      _article = value; 
      RaisePropertyChanged(); 
     } 
    } 

    public virtual int? NombreArticle

      RaisePropertyChanging(); 
      _nombreArticle = value; 
      RaisePropertyChanged(); 
     } 
    } 

    public virtual double PrixUnitaireArticle 
    {

    } 

    public virtual double PrixTotalArticle 
    {

Answer 1

您需要在您的dataG上设置AutoGenerateColumns属性为False因为你想自定义你的列。默认情况下它是真的。

<DataGrid AutoGenerateColumns="False"> 
    ..... 
</DataGrid> 

Answer 2

你有你的DataGrid.AutoGenerateColumns属性设置为false否则电网就会自动生成和你自定义的列将被忽略。
