Question

I have a listbox which contains 20-50 items. All items must be sorted by unique id.
After applying sort, my listbox scrolls at top. How to prevent that?
Sort function

public static void Sort<TSource, TValue>(IList<TSource> source, Func<TSource, TValue> selector) {
      for (int i = source.Count - 1; i >= 0; i--) {
        for (int j = 1; j <= i; j++) {
          TSource o1 = source.ElementAt(j - 1);
          TSource o2 = source.ElementAt(j);
          TValue x = selector(o1);
          TValue y = selector(o2);
          var comparer = Comparer<TValue>.Default;
          if (comparer.Compare(x, y) > 0) {
            source.Remove(o1);
            source.Insert(j, o1);
          }
        }
      }
    }

Only this helped

void loadItems(){
//load
    var t = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(1000) };
            t.Tick += delegate {
              _ScrollViewer.UpdateLayout();
              SomethingLoading = false;
              listmy.ScrollIntoView(listmy.Items[listmy.Items.Count - 10]);
            };
            t.Start();
}
