listviewgroup troubels

[JR212]

Hi, I need some help wilt listviewgroups. 1. How can I find the group that I click/dblclick. I tryed with

Private Sub ListViewCollapsible1_MouseDown(sender As Object, e As MouseEventArgs) Handles ListViewCollapsible1.MouseDown
Dim lv As ListViewCollapsible = sender
Dim lvi As ListViewItem = lv.HitTest(e.X, e.Y).Item

If lvi Is Nothing Then
  For n = 0 To (lv.Font.Size \* 2)
    Dim ht As ListViewHitTestInfo = lv.HitTest(e.X, e.Y + n)
    If ht.Item IsNot Nothing Then
      Dim g As ListViewGroup = ht.Item.Group
      Dim gs As New ListViewGroupState

      Dim sTag As String = g.Tag & " "
      If sTag.Contains("collapsed") Then
        lv.SetGroupState(ListViewGroupState.Normal, ht.Item.Group)
        ht.Item.Group.Tag = "Collapsed"
      Else
        lv.SetGroupState(ListViewGroupState.Collapsed, ht.Item.Group)
        ht.Item.Group.Tag = ""
      End If
      Exit For
    End If
  Next
End If

End Sub

but when the group is collapsed the code find nothing How can I add an icon to a group? I added an imagelist but groups don't have an imageindex. Jan
