Sort ListView by Date

Question

I have a WPF ListView with a column that has dates in it. I would like a way to custom sort the dates (by date value, rather than string value). Is there a way to do this? Right now I am using list.Items.SortDescriptions to sort using another column, but I would like to change this to sort on the date column instead.

Thanks.

Answer 1

Have you tried that ?

ICollectionView view = CollectionViewSource.GetDefaultView(listView.ItemsSource);
view.SortDescriptions.Add(new SortDescription("Date", ListSortDirection.Descending));

EDIT: You can also have a look at this attached property

Answer 2

If you're finding that the way WPF is sorting by default isn't what you intended, you can provide a custom sorter to the default view:

ListCollectionView view = 
  (ListCollectionView)CollectionViewSource.GetDefaultView(listView.ItemsSource);
view.CustomSort = new DateValueSorter();
listView.Items.Refresh();

Where DateValueSorter is a class that implements the IComparer interface and sorts according to the date value and produces the ordering you are looking for.

Answer 3

Use ObservableList and a custom object type - and do the sorting yourself. Connect the ListView to the ObservableList using ItemsSource.
