So you are saying you can sort on any column. Thats not exactly what I was asking, but it is very useful information. I am having problems implementing it though. When I select the ColumnClick method I get this instead.

Private Sub lstRouteSegments_ColumnClick(ByVal sender As Object, _
ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles _
lstRouteSegments.ColumnClick
Me.lstRouteSegments.SortKey = ColumnHeader.Index - 1
End Sub

And my listview doesn't have the sortkey property and also ColumnHeader is not recognized. What am I doing wrong?
