Get all the childs from treeview

[simmo09]

This is driving me mad, i have my treeview setup something like:

-PARENT1
---aChild1
---aChild2
-PARENT2
---aChild1
---aChild2
---aChild3

..etc..

what i need to do is two things:

1) when i click on PARENT1 OR PARENT2, i need to delete all its childs

2) then add childs under whichever parent was selected, so far i have only got this which adds to the treeview, but everytime i click the parent its duplicating and duplicating:

DelphiTreeNode:= tvwMain.Selected;

for l:= 0 to lvwMain.Items.Count -1 do
begin
  with tvwMain.Items.AddChild(DelphiTreeNode, lvwMain.Items.Item[l].SubItems[0]) do
  begin
    ImageIndex:= 0;
    SelectedIndex:= 0;
  end;
end;

I think this would be easy if i know how to delete all childs under the parent i select each time.

Thanks
