问题 I have a listbox with more than 20 items. How I can scroll to bottom of it? I tried the ScrollIntoView method, but no success: listmy.SelectedIndex = listmy.Items.Count;// listmy.Items.Count - 1; listmy.ScrollIntoView(listmy.SelectedIndex); listmy.UpdateLayout(); 回答1: The ScrollIntoView method expects an object (the item to scroll to), but you are passing in the numeric index of the selected item.

That limitation of course completely invalidates any attempt at having navigation run in the background as you can get pretty damn far off-track in fifteen minutes, let alone that a background task can only run once every thirty minutes or so! That
