WPF; How to deselect all my selected items when clicking on an empty space in my ListView

When I have several (or even one) selected items

and I click a simple one click

on an empty space in my ListView

(empty space = not a row), I want to deselect all my selected items.

This is my function to deselect all items:

private void DeselectAllListViewItems()
{
    MyListView.SelectedItems.Clear();
}

I am trying to grab the selected index using this function:

private void MyListView_MouseDown(object sender, MouseButtonEventArgs e)
{
    if (MyListView.SelectedIndex == -1)
        DeselectAllListViewItems();
}

But in case I have multiple selected items (or one ...), the selected index will never be -1. So how can I tell mine mouse click

is in the blank space and not in the position line?

The code below works well enough.

private void MyListView_MouseDown(object sender, MouseButtonEventArgs e)
{
    HitTestResult r = VisualTreeHelper.HitTest(this, e.GetPosition(this));
    if (r.VisualHit.GetType() != typeof(ListBoxItem))
        listView1.UnselectAll();
}


WPF Listbox remove selection by clicking on blank space
