안녕하세요, 부모 속성에서 바인딩 가시성이 두 가지 모드. standar을 제어 은 가능한 탐 사용이 : 바인딩 가시성 any 부모
<Window.Resources>
<BooleanToVisibilityConverter x:Key="BoolToVis"/>
</Window.Resources>
<Button x:Name="buttonTest" Width="75" Visibility="{Binding IsModify, Converter={StaticResource BoolToVis}}"/>
하지만 가시성을 결합 내 UserControl을에 나는 단지이 방법
, 그렇지 않으면하지 않습니다 작품 : 내가해야하는 이유<local:UserControl4 Height="100" Width="100" Visibility="{Binding ElementName=Window1,Path=IsModify,Converter={StaticResource BoolToVis}}"/>
내 질문은 내 컨트롤의 가시성에서 요소 이름과 ParentProperty를 전달하지만 버튼은 안된다.
이
는 코드 숨김public static readonly DependencyProperty IsModifyProperty =
DependencyProperty.Register("IsModify", typeof(Boolean), typeof(MainWindow), new PropertyMetadata(false));
[DefaultValue(false)]
public Boolean IsModify
{
get { return (Boolean)GetValue(MainWindow.IsModifyProperty); }
set
{
SetValue(MainWindow.IsModifyProperty, value);
this.OnPropertyChanged("IsModify");
}
}
이며,이 여기에 생성자
public MainWindow()
{
InitializeComponent();
this.DataContext = this;
}
오류를 복제 할 소스 코드입니다. 하나의 창과 하나의 usercontrol이있는 프로젝트가 하나 필요합니다. 창 ---- XAML위한

나는 문제가 생성자에서 생각 This.datacontext =이; 하지만 속성 설명을 바인딩하려는 경우 필수 항목입니다. 사전
