Xceed WPF propertyGrid自定义集合编辑器
Xceed WPF propertyGrid自定义集合编辑器
提问于 2015-06-23 11:57:32
我是WPF的新手，我正在使用xceed属性网格，在我的类中我有一个自定义的集合编辑器。根据xceed，我发现我必须实现"Xceed.Wpf.Toolkit.PropertyGrid.Editors.ITypeEditor"，--我已经实现了它，但是当我试图设置绑定时会出错。错误信息：“双向绑定需要路径或XPath”。下面是c#类，其中定义了属性：
/// <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绑定：
<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”的实现还没有完成，我需要帮助解决这个问题。

你的意思是这样的：
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; }
