WPF自定义控件 Name属性问题

[PirloL]

我自己编写了一个自定义控件，然后MainWindow.xmal中调用，Name属性赋值了，但是后台取不到。改成x：Name，编译报错：错误 2 类型“ControlTree”不能具有 Name 特性。值类型和没有默认构造函数的类型可以用作 ResourceDictionary 中的项。 行 7 位置 27. F:\c#\TreeControl\WpfTree\MainWindow.xaml 7 27 WpfTree。求大神指导！

ControlTree简要代码？ControlTree继承自？ControlTree的构造函数？

[PirloL]

继承UserControl ControlTree.xmal.cs

     public partial class ControlTree : UserControl
    {
        DataTable dt_;
        public ControlTree(DataTable ParamDT)
        {
            InitializeComponent();
            LoadedTree(ParamDT);
        }

        public DataTable DTSource
        {
            set
            {
                dt_ = value;
            }
            get
            {
                return dt_;
            }
        }

        public string Name
        {
            get{ return this.Name;}
            set { this.Name = value; }
        }

        private void LoadedTree(DataTable ParamDT)
        {
            if (treeView1.Items.Count > 0)
            {
                return;
            }

            //定义树模版
            HierarchicalDataTemplate tpl = new HierarchicalDataTemplate(typeof(TreeNode));
            tpl.ItemsSource = new Binding("SubNode");
            FrameworkElementFactory factoryTextBlock = new FrameworkElementFactory(typeof(TextBlock));
            factoryTextBlock.SetBinding(TextBlock.TextProperty, new Binding("Name"));
            tpl.VisualTree = factoryTextBlock;

            TreeNode rootRsc = new TreeNode("", "", "", ParamDT);
            foreach (TreeNode temp in rootRsc.SubNode)
            {
                TreeViewItem rootItem = new TreeViewItem();
                rootItem.Header = temp.Name;
                rootItem.ItemsSource = temp.SubNode;
                rootItem.ItemTemplate = tpl;
                rootItem.IsExpanded = true;
                treeView1.Items.Add(rootItem);
            }
        }
    }

MainWindow.xma;:

<Window x:Class="WpfTree.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:tree="clr-namespace:WpfTree"
        Title="MainWindow" Height="350" Width="525">
    <Grid Name="grid1">
        <tree:ControlTree Name="tree1"></tree:ControlTree>
    </Grid>
</Window>

tree1后台找不到，改成x:Name就报问题中的错误了

[Bonjour-你好]

在 ControlTree.xmal.cs 中新增一个这样的无参构造函数：

public ControlTree()
{
    InitializeComponent();
}
