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

我正在将MVVM Light与SL4结合使用。我的视图通过定位器解决了他们的视图模型，一切都很好。Silverlight MVVM Light - 从xaml设置控件依赖项属性值

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。

即一个HomeView可以有一个组件视图的许多实例。但在该主视图上，我想在组件视图上设置属性。我已经尝试添加一个依赖项属性到视图后面的代码中 - 然后我可以从HomeView中设置它，但是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); 
}

ComponentViewModel.cs

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

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

ComponentView.xaml.cs

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

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

ComponentView.xaml

<Grid> 
    <common:ComponentControl 
      DataContext="{Binding Path=WorkflowList, Mode=OneWay}" 
      CustomType="{Binding Path=CustomType, Mode=TwoWay, 
           ElementName=root}" /> 
</Grid>

HomeView.xaml

<Grid x:Name="LayoutRoot"> 
    <common:HomeControl x:Name="homeControl"> 
     <common:HomeControl.ActiveContent> 
      <local:ComponentView x:Name="active" CustomType="Active" /> 
     </common:HomeControl.ActiveContent> 
     <common:HomeControl.DraftContent> 
      <local:ComponentView x:Name="draft" CustomType="Draft" /> 
     </common:HomeControl.DraftContent> 
     <common:HomeControl.CompletedContent> 
      <local:ComponentView x:Name="completed" CustomType="Completed" /> 
     </common:HomeControl.CompletedContent> 
    </common:HomeControl> 
</Grid>
