我的自定义控件在我的控制库程序集中：

public class TestControl : Control
{
    public static readonly DependencyProperty TestPropProperty =
        DependencyProperty.Register("TestProp",typeof(string),typeof(TestControl),new UIPropertyMetadata(null));

    public string TestProp
    {
        get { return (string)GetValue(TestPropProperty); }
        set { SetValue(TestPropProperty,value); }
    }

    static TestControl()
    {
        DefaultStyleKeyProperty.OverrideMetadata(typeof(TestControl),new FrameworkPropertyMetadata(typeof(TestControl)));
    }
}

及其XAML模板：

<Style TargetType="{x:Type local:TestControl}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:TestControl}">
                <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                    <StackPanel>
                        <TextBlock Text="Testing..." />
                        <Label Content="{Binding TestProp}" Padding="10" />
                    </StackPanel>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

这是在wpf窗口中使用引用我的控制库的XAML消费控件：

<Grid>
    <ItemsControl Name="mylist">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <my:TestControl TestProp="{Binding Path=Name}" />
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Grid>

这里是代码：

public partial class Test2 : Window
{
    public class TestObject : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
        protected void OnPropertyChanged(string PropertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this,new PropertyChangedEventArgs(PropertyName));
        }

        private int _id;
        public int id
        {
            get { return _id; }
            set { _id = value; OnPropertyChanged("id"); }
        }

        private string _Name;
        public string Name
        {
            get { return _Name; }
            set { _Name = value; OnPropertyChanged("Name"); }
        }
    }

    public Test2()
    {
        InitializeComponent();

        mylist.ItemsSource = new TestObject[]
        {
            new TestObject(){ id = 1,Name = "Tedd" },new TestObject(){ id = 2,Name = "Fred" },new TestObject(){ id = 3,Name = "Jim" },new TestObject(){ id = 4,Name = "Jack" },};
    }
}

运行这个例子给了我四个控件的实例,但是我只看到每一个“测试…”TextBlock.我的标签永远不会被束缚.我有什么误会和做错了？
