What type does the watch window say the subitem is? Even if a class is
cast
to a base class the watch will correctly ID the correct class.

It's a ListViewItem.ListViewSubItem like it's supposed to be. Try it,
it just doesn't seem to work for some reason.

Try this for a general 'catcher'
private void listView1_SelectedIndexChanged(object sender, System.EventArgs
e)
{
ListViewItem lvi = listView1.SelectedItems[0];
for(int i=0; i< lvi.SubItems.Count; i++)
{
if(lvi.SubItems[i] is CustListViewSubItem)
{
DoCustThings();
}
else if(lvi.SubItems[i]is ListViewItem.ListViewSubItem)
{
DoBaseThings();
}
}
}
