Use a complex custom sort in ListView

Question

I can't find how to add custom sorting to WPF ListView control? I don't need to sort by columns asc or desc, I need a custom one with some algorithm in it?

can you help me?

Thank you!

You can use CustomSort property on ListCollectionView provided that you implement IComparer for your class:

//somewhere in code behind of your window:
var view = (ListCollectionView)CollectionViewSource.GetDefaultView(Items); //Items is an ObservableCollection<T> 
view.CustomSort = new MyComparer(); //MyComparable implements IComparer

Any control bound to your Items such as ListBox will display elements in order.
