Silverlight MVVM Light-从xaml设置控件依赖项属性值

我在SL4上使用MVVM灯。我的视图正在通过定位器解析视图模型，一切正常

我的问题是，我的一个视图有一个属性，我需要在另一个视图中设置该属性

i、 e.HomeView可以有多个组件视图实例。但是在主视图上，我想在组件视图上设置属性。我曾尝试向视图的代码隐藏中添加依赖项属性，然后可以从HomeView中设置该属性，但我的组件视图模型没有选择它

这可能吗

ComponentControl.cs

public enum CustomStyle
{
    Active,
    Draft,
    Completed
}

public class ComponentControl : Control
{
    public ComponentControl()
    {
        DefaultStyleKey = typeof (ComponentControl);
    }

    public CustomStyle CustomType
    {
        get { return (CustomStyle)GetValue(CustomTypeProperty); }
        set { SetValue(CustomTypeProperty, value); }
    }

    public static readonly DependencyProperty CustomTypeProperty =
        DependencyProperty.Register("CustomType",
        typeof(CustomStyle),
        typeof(ComponentControl), null);
}

public CustomStyle CustomType
{
    get { return _customType; }
    set
    {
        if (value == _customType)
            return;

        _customType = value;
        base.RaisePropertyChanged("CustomType");
    }
}
private CustomStyle _customType;

public static readonly DependencyProperty CustomTypeProperty =
    DependencyProperty.Register("CustomType", 
    typeof(CustomStyle),

我想我可以帮你一点忙，刚才我回答了一个类似的问题：

我的示例中的子视图包含一个dependency属性，它的值在父视图中设置。子视图使用带有ElementName=“this”的绑定绑定到该依赖项属性
