WPF Scatterview items - how to clear all the items by clicking a button?

I created a button and wrote its behaviour to clear the scatter view, but it didnt work:

private void Button1_Click(object sender, RoutedEventArgs e)
        {
            DependencyObject parent = VisualTreeHelper.GetParent(this);
            ScatterViewItem svi = null;
            while (parent as ScatterView == null)
            {
                if (parent is ScatterViewItem)
                    svi = parent as ScatterViewItem;
                parent = VisualTreeHelper.GetParent(parent);
            }

            ((ScatterView)parent).Items.Remove(svi);              
        }

Before this, I thought to reset the application by this code which didnt work either: (I added using System.Diagnostics; )

private void Button1_Click(object sender, RoutedEventArgs e)
    {    
       Process.Start(Application.ResourceAssembly.Location);    
       Application.Current.Shutdown();                      
    }

the xaml:

<s:SurfaceButton  Content="Clear" Name="Button1" Click="Button1_Click" VerticalAlignment="Bottom" HorizontalAlignment="Center"/>

can you tell me what i miss, thanks

You can simply give the ScatterView a name

<s:ScatterView x:Name="scatterView" ... />

and then access it from code behind:

private void Button1_Click(object sender, RoutedEventArgs e)
{
    scatterView.Items.Clear();
}
