Xceed WPF propertyGrid自定義集合編輯器

Question

我是WPF的新手，我使用xceed屬性網格，在我的課程中，我有一個自定義集合編輯器。 按照xceed，我發現我必須實現“ Xceed.Wpf.Toolkit.PropertyGrid.Editors.ITypeEditor”，但是已經實現了，但是在嘗試設置綁定時出現錯誤。 錯誤消息：“雙向綁定需要路徑或XPath”。 下面是c＃類，其中定義了屬性：

 /// <summary>
/// The expected assembly versions.
/// </summary>
[DescriptionAttribute("The expected assembly versions.")]
[Category("Mandatory")]
[ExpandableObject]
[Editor(typeof(Assembly), typeof(Assembly))]
public Assembly[] ExpectedAssemblyVersions
{
  get;
  set;
}
   /// <summary>
/// To verify assembly and there versions
/// </summary>
[TypeConverterAttribute(typeof(ExpandableObjectConverter))]
public class Assembly : Xceed.Wpf.Toolkit.PropertyGrid.Editors.ITypeEditor
{
  /// <summary>
  /// Assembly Name
  /// </summary>
  public string Name { get; set; }
  /// <summary>
  /// Assembly versions
  /// </summary>
  public string[] Versions { get; set; }

  #region Implementation of ITypeEditor
  /// <summary>
  /// 
  /// </summary>
  /// <param name="propertyItem"></param>
  /// <returns></returns>
  public FrameworkElement ResolveEditor(PropertyItem propertyItem)
  {
    TextBox textBox = new TextBox();
    var _binding = new Binding(Name);
    _binding.Source = propertyItem;
    _binding.ValidatesOnExceptions = true;
    _binding.ValidatesOnDataErrors = true;
    _binding.Mode = propertyItem.IsReadOnly ? BindingMode.OneWay : BindingMode.TwoWay;
    BindingOperations.SetBinding(textBox, TextBox.TextProperty, _binding);
    return textBox;
  }
  #endregion
}

XAML綁定：

<xctk:PropertyGrid Name="pk" Foreground="{Binding SelectedTheme.FontShade}" HorizontalAlignment="Stretch"  VerticalAlignment="Stretch" FontWeight="ExtraBold"  Background="{Binding SelectedTheme.DarkShade}" SelectedObject="{Binding SelectedElement,UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>

“ ResolveEditor”的實現不完整，我需要幫助解決此問題。

您的意思是這樣的嗎：

class Properties
{
    private List<Assembly> assemblies = new List<Assembly>();

    [DisplayName("ExpectedAssemblyVersions")]
    [Description("The expected assembly versions.")]
    [Category("Mandatory")]
    [Editor(typeof(CollectionEditor), typeof(CollectionEditor))]
    public List<Assembly> Assemblies
    {
        get
        {
            return assemblies;
        }
        set
        {
            assemblies = value;
        }
    }
}

class Assembly
{
    public string Name { get; set; }

    public string Version { get; set; }
}
