Silverlight - 公开子模板依赖项属性

Question

我创建了一个自定义的silverlight模板控件，它包含两个部分，一个是ContentControl，一个是ItemsControl。我已成功创建了一个在自定义模板控件中使用它们的模板，但我想将部件的内部模板公开给Blend，这样就可以对它们进行编辑，并使用默认值进行公开。

我尝试了以下代码的各种变体，试图让它工作，但没有成功。

    [TemplatePart(Name = ExpanderTemplateControl2.PartName_FullViewItem, Type = typeof(ExpanderFullViewItem))]
[TemplatePart(Name = ExpanderTemplateControl2.PartName_ItemsControl, Type = typeof(ItemsControl))]
public class ExpanderTemplateControl2 : Control
{
    public const string PartName_FullViewItem = "PART_FullViewItem";
    public const string PartName_ItemsControl = "PART_ItemsControl";

    #region Parts

    private ContentControl part_FullViewItem;
    private ItemsControl part_ItemsControl;

    #endregion


    static ExpanderTemplateControl2()
    {
        //DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomListControl), new FrameworkPropertyMetadata(typeof(CustomListControl)));

        //Add Ownership of dependency property
        ItemTemplateProperty = ItemsControl.ItemTemplateProperty;//.AddOwner(typeof(ExpanderTemplateControl2));
        ItemsPanelProperty = ItemsControl.ItemsPanelProperty;//.AddOwner(typeof(ExpanderTemplateControl2));
        FullViewTemplateProperty = ContentControl.TemplateProperty;//.AddOwner(typeof(ExpanderTemplateControl2));
    }

    public ExpanderTemplateControl2()
    {
        this.DefaultStyleKey = typeof(ExpanderTemplateControl2);
    }


    #region Dependency Properties

    public static readonly DependencyProperty ItemTemplateProperty;
        //= DependencyProperty.Register("ItemTemplate", typeof(DataTemplate), typeof(ExpanderTemplateControl2), new PropertyMetadata(null));

    public static readonly DependencyProperty ItemsPanelProperty;
        //= DependencyProperty.Register("ItemsPanel", typeof(ItemsPanelTemplate), typeof(ExpanderTemplateControl2), new PropertyMetadata(null));

    public static readonly DependencyProperty FullViewTemplateProperty;
        //= DependencyProperty.Register("FullViewItemTemplate", typeof(ControlTemplate), typeof(ExpanderTemplateControl2), new PropertyMetadata(null));

    #endregion



    #region Properties

    [BindableAttribute(false)]
    public DataTemplate ItemTemplate
    {
        get { return (DataTemplate)GetValue(ItemTemplateProperty); }
        set { SetValue(ItemTemplateProperty, value); }
    }

    [BindableAttribute(false)]
    public ItemsPanelTemplate ItemsPanel 
    {
        get { return (ItemsPanelTemplate)GetValue(ItemsPanelProperty); }
        set { SetValue(ItemsPanelProperty, value); }
    }

    [BindableAttribute(false)]
    public ControlTemplate FullViewTemplate
    {
        get { return (ControlTemplate)GetValue(FullViewTemplateProperty); }
        set { SetValue(FullViewTemplateProperty, value); }
    }

    #endregion
}

任何人都可以给我一些指示吗？

干杯

更新：通过执行以下操作，我已设法将其置于某种工作状态，但我对此并不满意。还有更好的方法吗？
