WPF; How Deselect all my selected items when click on empty space in my ListView

Question

When i have several (or even one) selected items and i press simple click on empty space in my ListView (empty space = not row) i want to deselect all my selected items.

This is my deselect all item function:

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

I try to take the selected index with this function:

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

But in case i have several selected items (or one..) the selected index will never be -1. So how can i distinguish that my mouse click is on empty space and not on item row ?

The code below works quite well.

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