Say I store the CollectionView as a property : You can add them in the collectionView to get desired output. The CollectionView actually maintains a stack of SortDescription objects, each of them being a Structure can hold information of a Column and the Direction of Sorting. You need to add a SortDescription to the CollectionView. Sorting can be applied to the CollectionView in a very easy way.

Now let us look how to implement the basic features for the ICollectionView. So the CollectionView actually separates the View object List Control with the actual DataSource and hence gives an interface to manipulate the data before reflecting to the View objects. The List will get the CollectionView it requires. = CollectionViewSource.GetDefaultView( this.Source) Just you need to pass the Enumerable to CollectionViewSource.GetDefaultView. Practically speaking, getting a CollectionView from an Enumerable the most easiest thing I ever seen in WPF. Therefore in other words, a CollectionView is a class which takes care of the View totally and giving us the capability to handle certain features incorporated within it. It is a layer that runs over the Data Objects which allows you to define rules for Sorting, Filtering, Grouping etc and manipulate the display of data rather than modifying the actual data objects. So I thought I would consider to describe it a bit so that people might easily plug in the same to their own solution. It is been very popular to those working with data object because of inbuilt support for all WPF List controls. Thus it ensures that all the related information like filtering, sorting etc is decoupled from the actual control. It is the primary Data object for any WPF list controls (like ComboBox, ListBox, ListView etc) that allows flexibilities like Sorting, Filtering, Grouping, Current Record Management etc. If you are working with WPF for long, you might already have come across with ICollectionView.
