c# - 为什么 Browsable(false) 不隐藏 DataGrid 中的列

Question

在我的 WPF 应用程序中，我想通过向某些属性添加 [Browsable(false)] 来隐藏具有绑定(bind) ItemsSource 的 DataGrid 中的列但是，无论有无 Browsable(false)，所有列都是可见的。

我的模型:

public class Room : INotifyPropertyChanged
{
    private int id;
  ...
    [Browsable(false)]
    public int Id
    {
        get
        {
            return this.id;
        }
        set
        {
            this.id = value;
            this.OnPropertyChanged("Id");
        }
    }
    ...
    public Room()
    {
    }
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler propertyChangedEventHandler = this.PropertyChanged;
        if (propertyChangedEventHandler != null)
        {
            propertyChangedEventHandler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
}

查看:

<DataGrid Grid.Row="1" ItemsSource="{Binding Rooms}" SelectedItem="{Binding SelectedRoom, Mode=TwoWay}" />

如何使用 Browsable(false) 隐藏列？

您可以通过连接 DataGrid 上的 AutoGeneratingColumn 事件来隐藏它们(参见 https://stackoverflow.com/a/3794324/4735446)。

public class DataGridHideBrowsableFalseBehavior : Behavior<DataGrid>
{
    protected override void OnAttached()
    {
        AssociatedObject.AutoGeneratingColumn += AssociatedObject_AutoGeneratingColumn;
        base.OnAttached();
    }

    private void AssociatedObject_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
    {
        if (((PropertyDescriptor)e.PropertyDescriptor).IsBrowsable == false)
            e.Cancel = true;
    }
}


<DataGrid
    ItemsSource="{Binding Path=DataGridSource, Mode=OneWay}"
    AutoGenerateColumns="true">
        <i:Interaction.Behaviors>
            <behaviors:DataGridHideBrowsableFalseBehavior>
             </behaviors:DataGridHideBrowsableFalseBehavior>
        </i:Interaction.Behaviors>
</DataGrid>
