How can you scroll a List Box to the bottom in C#? The items in the ListBox don't have names, which may make it more difficult.

it seems to scroll almost to the end of the ListBox but seems to stop halfway through the last item. – Newbie Jul 23 '13 at 18:04

In C#:

yourListBox.SelectedIndex = yourListBox.ItemsSource.Count();

If for some reason you do not have Count, try this:

public static int Count<TSource>(this IEnumerable<TSource> source)
{
  if (source == null)
    throw new ArgumentNullException("source");
  ICollection collection = source as ICollection;
  if (collection != null)
    return collection.Count;
  int num = 0;
  foreach (TSource item in source)
      checked { ++num; }
  return num;
}

This brings up an error, saying there is no definition for .Count andthere is no extension method for .Count – Newbie Jul 23 '13 at 11:11
@Newbie Add `using System.Linq;` to the top of your file. – It'sNotALie. Jul 23 '13 at 11:12
I am already using System.Linq; as its a default statement for windows phone projects – Newbie Jul 23 '13 at 13:14
@newStackExchangeInstance Can't he use `yourListBox.Items.Count` directly? – anderZubi Jul 23 '13 at 13:41
@anderZubi Not if it's not an ICollection, no. – It'sNotALie. Jul 23 '13 at 13:50
