I can't seem to figure out how to sort a ListView by anything but the first
column.  I don't seem to see a way to set this property in the ListView or
the ListView.Columns objects.  It seems like one way would be to swap the
column you want to sort by and the first column, sort the list, then swap
them back, but that doesn't seem like it should be necessairy.

Thanks Michael

Hi Michael,

First of all you should have class implementing IComparer interface. Then
you create an instance of this class and set instance reference to
ListViewItemSorter property of listview.

When listview will sort items it will call Compare method of your class
passing two ListViewItems. All you have to do inside Compare method is to
compare :-) and return 0 if items are equal, -1 if item1 is less than item 2
or 1 if item1 is greater than item 2.

Following is a sample of this, assuming SubItem[1] is of String type:
        public class ListViewComparer : IComparer
        {
                public int Compare( object item1, object item2 )
                {
                        if( !(item1 is ListViewItem) || !(item2 is ListViewItem) )
                                return 0; // We don't know type - so both objects are same for us

                        ListViewItem lvi1 = (ListViewItem) item1;
                        ListViewItem lvi2 = (ListViewItem) item2;

                        return String.Compare( lvi1.SubItems[1].ToString(),
(string)lvi2.SubItems[1].ToString() );
                }
        }
