     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" Height="60" Width="150"> 
<Grid> 
    <Border BorderThickness="2" BorderBrush="Red" Background="Black"> 
     <Grid> 
      <Grid.RowDefinitions> 
       <RowDefinition Height="*"/> 
       <RowDefinition Height="*"/> 

      </Grid.RowDefinitions> 
      <TextBlock Text="Abcd" Background="Red"/> 
    <Button Content="Delete" Grid.Row="1" Click="Button_Click"/> 
     </Grid> 
    </Border> 
</Grid> 

public partial class UserControl1 : UserControl 
{ 
    public UserControl1() 
    { 
     InitializeComponent(); 
    } 

    public Action Delete; 

    private void Button_Click(object sender, RoutedEventArgs e) 
    { 
     if(Delete!=null) 
      Delete(); 
    } 

} 

<Window x:Class="WpfApplication1.MainWindow"

      </Grid> 
     </GroupBox.Content> 
    </GroupBox>

public partial class MainWindow : Window 
{ 
    public MainWindow() 
    { 
     InitializeComponent(); 
     DataContext = this; 
     uc2.Delete += OnDelete; 
    } 
    private void OnDelete() 
    { 
     LayoutRoot.Children.Remove(uc2); 
    } 
}
