Another solution is to keep the selected index of each listbox in two separate variables and then delete each item by the index stored beforehand.

try to delete them in another order:

  listBox2.Items.Remove(listBox2.SelectedItem);
  listBox1.Items.Remove(listBox1.SelectedItem);

When you deleted the selecteditem at the first ListBox, SelectionChanged is firing and set SelectedItem of listbox2 into null.
