Twoway 바인딩이 DataGrid.Resources 내에서 작동하지 않습니다.

Question

DataGrid.Resources를 사용하여 제대로 작동하려면 TwoWay Binding을 가져올 수 없습니다. TextBox는 편집 할 행과 함께 나타납니다. 행을 종료하면 해당 행에 바인딩 된 개체가 새 값으로 업데이트되지 않습니다 (INotifyPropertyChanged를 구현하는 개체의 중단 점을 테스트 한 결과).

DataBrid.Resources의 외부에 여러 개의 Datatemplates를 작성하기 전에 데이터 바인딩이 제대로 작동하고있었습니다.

. 바라기를 이것은 동일한 문제점을 가진 누군가를 도울 것입니다.

DataTemplateSelector 클래스를 만든 다음 해당 클래스를 XAML에서 호출해야했습니다. 아래는 Template Selector 클래스와 함께 새로운 XAML 코드의 복사본입니다.

<Window.Resources> 
     <DataTemplate x:Key="ProviderStringTemplate" DataType="{x:Type System:String}"> 
      <TextBox VerticalAlignment="Center" Text="{Binding Value, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" Width="200" /> 
     </DataTemplate> 
     <DataTemplate x:Key="ProviderBooleanTemplate" DataType="{x:Type System:Boolean}"> 
      <CheckBox Margin="15,0,0,0" VerticalAlignment="Center" IsChecked="{Binding Value, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" /> 
     </DataTemplate> 
     <Windows:ProviderPropertyTemplateSelector x:Key="templateSelector" /> 
    </Window.Resources>

    public class ProviderPropertyTemplateSelector : DataTemplateSelector

     public override DataTemplate SelectTemplate(object item, DependencyObject container)

      var property = item as Property<object>;

       return null; 

      if (property.Value is Boolean) 
       return ((FrameworkElement)container).FindResource("ProviderBooleanTemplate") as DataTemplate; 

      if (property.Value is String || property.Value is int) 
       return ((FrameworkElement)container).FindResource("ProviderStringTemplate") as DataTemplate; 

      return null; 
     } 
    }
