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();  
    }  
  }  
}  

The result:
