Silverlight 하위 창에서 바인딩 문제가 발생했습니다.

Question

Silverlight 그리드를 배치 한 Silverlight 자식 창을 사용하고 있습니다. 샘플 코드는 아래에 언급 : 네임 스페이스로

<controls:ChildWindow x:Class="Bixi.Atlas.Client.UI.OrganisationModule.Views.CostCenters.Lookup"

컨트롤은 내가 사용할 수 있습니다 :

<UserControl.Resources> 
    <viewmodel:ViewModelLocator x:Key="PersonLookupViewModel"/>  
</UserControl.Resources>
