你的问题在各种方式严重制定和代码示例太大.. – franssu

你的视图模型在哪里？ – RQDQ

在你内心的网格，可以将所选项目中的转换器应用于可视性。

在XAML中添加此资源：

<local:NotNullToVisibilityConverter x:Key="NotNullToVisibilityConverter" />

并使用它在你的孩子电网这样的：

<Grid Grid.Row="1" Visibility={Binding SelectedEmployee, Converter={StaticResource NotNullToVisibilityConverter}} ...>

这里是转换器代码：

public class NotNullToVisibilityConverter : IValueConverter 
    { 
     public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      if (value == null) 
       return Visibility.Hidden; // or Visibility.Collapsed 

      return Visibility.Visible; 
     } 

     public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
     { 
      throw new NotImplementedException(); 
     } 
    }
