+Summary: ListView: navigating with the cursor keys after Items.Clear and SelectedItems.Clear
+
+When you clear all items in a ListView and then add new items navigating
+with the cursor keys is no longer possible.
+
+To reproduce this, open the filedialog sample. Select an item in the file
+ListView. Hit backspace and try to navigate with the cursor keys again.
+
+At least here it crashes immediately.
+
+Expected behaviour would be that the first of the new items has the focus.
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
