Collection View

Data should be separated out from UI Elements for data binding purposes. In fact, Sorting, Grouping, selected changed event ( as in IBindingList) are better handled in View ( such as DataView and ListCollectionView). Here is a simple usage of Collection View in WPF:

    public class Stock
    {
        public string Symbol { get; set; }
        public double Price { get;set;}
        public Stock(string s, double p)
        {
            this.Price = p;
            this.Symbol = s;
        }

        public override string ToString()
        {
            return Symbol + " " + Price;
        }
    }

            List<Stock> stocks = new List<Stock>();
            stocks.Add(new Stock("YHOO", 27.90));
            stocks.Add(new Stock("MSFT", 28.90));
            stocks.Add(new Stock("GOOG", 179.40));
            ListCollectionView cv = new ListCollectionView(stocks);
            cv.SortDescriptions.Add(new SortDescription("Symbol", ListSortDirection.Ascending));
            Binding b = new Binding();
            b.Source = cv;
            this.listBox1.SetBinding(ListBox.ItemsSourceProperty, b);
