Custom Sort of ObjectListView

can somebody help me? I am trying to do custom sort of items in objectlistview. I have found a method using BeforeSorting event. Items are sorted, but objectlistview are showing "old data". The source of items for objectlistview is _shows.

private void objectListView1_BeforeSorting(object sender, BeforeSortingEventArgs e)
    {
        _shows.OrderByDescending(s => s.Name != "News").ThenBy(s => s.Name);
        e.Handled = true;
    }

Thank you!!

Solution

  • You are not using the returned sorted collection, it should be:

    _shows = 
_shows.OrderByDescending(s => s.Name != "News").ThenBy(s => s.Name);

    This will result in IOrderedCollection, in case _shows is a List, then to ToList() post ThenBy

    Post this I assume that you rebind the Datagridview with the data source _shows and thus the correct values will be reflected
