问题 I want to override the selection behavior of ListBox Items. We can traverse through ListBox items using Up and Down arrows but I want to traverse the list using Left and Right arrow keys. While I am trying to add the key down event for ListBox, It shows almost all key presses except for Arrow Keys, Home, End and similar keys. I have the following code: private void listArtist_KeyDown(object sender, System.Windows.Input.KeyEventArgs e) { if (e.Key.ToString() == "Enter") { // Go to some page }
