将Silverlight UserControl自定义属性绑定到其元素

public class MyUserControl : UserControl
{
    public static readonly DependencyProperty MyCustomPropertyProperty =
        DependencyProperty.Register("MyCustomProperty", typeof(string), typeof(MyUserControl), null);

    public string MyCustomProperty
    {
        get { return (string)GetValue(MyCustomPropertyProperty); }
        set { SetValue(MyCustomPropertyProperty, value); }
    }
}

<UserControl x:Class="MyUserControl"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:MyUserControlNamespace">
    <Grid>
        <TextBlock Text="{Binding MyCustomProperty, ElementName=UserControl}" />
    </Grid>
</UserControl>

public partial class MyUserControl : UserControl
{
    public MyUserControl()
    {
        InitializeComponent();
        this.MyCustomProperty = "Hello, World!";
    }

    public string MyCustomProperty
    {
        get { return (string)GetValue(MyCustomPropertyProperty); }
        set { SetValue(MyCustomPropertyProperty, value); }
    }

    private static void OnMyCustomPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        MyUserControl control = d as MyUserControl;
        control.MyCustomProperty = e.NewValue as string;
    }
}
