    Here is an example of binding the visibility of a Button to a Border. (The visibility of child controls in Border is consistent with Border.)
    MainWindow.xaml:

    <Window.Resources>  
            <local:BooleanToVisibilityConverter x:Key="BoolToVisConv"/>  
        </Window.Resources>  
        <Grid>  
            <Grid.ColumnDefinitions>  
                <ColumnDefinition/>  
                <ColumnDefinition/>  
            </Grid.ColumnDefinitions>  
            <Grid.RowDefinitions>  
                <RowDefinition/>  
                <RowDefinition/>  
            </Grid.RowDefinitions>  
            <Border x:Name="border" Grid.Column="1" Grid.Row="1" BorderBrush="Black" BorderThickness="1"   
                    Visibility="{Binding IsChecked, ElementName=toggleButton, Converter={StaticResource BoolToVisConv}}" >  
                <Button x:Name="btn" Content="button1" Width="200" Height="100"  />  
            </Border>  
            <ToggleButton x:Name="toggleButton" Grid.Column="1" Content="visibility" Width="200" Height="100"    />  
            <Button Width="100" Height="100" Content="button"  Visibility="{Binding IsVisible, ElementName=border, Converter={StaticResource BoolToVisConv}}"/>  
        </Grid>  
    

    MainWindow.xaml.cs:

    using System.Windows;  
    using System.Windows.Data;  
    
    namespace BorderAndButtonVisibility  
    {  
      public partial class MainWindow : Window  
      {  
        public MainWindow()  
        {  
          InitializeComponent();  
        }  
      }  
      public class BooleanToVisibilityConverter : IValueConverter  
      {  
        private object GetVisibility(object value)  
        {  
          if (!(value is bool))  
            return Visibility.Hidden;  
          bool objValue = (bool)value;  
          if (objValue)  
          {  
            return Visibility.Visible;  
          }  
          else  
          {  
            return Visibility.Hidden;  
          }  
        }  
        public object Convert(object value, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)  
        {  
          return GetVisibility(value);  
        }  
        public object ConvertBack(object value, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)  
        {  
          throw new System.NotImplementedException();  
        }  
      }  
    }
