Hello,

Try this. It works by starting with the last node in the treeview and working its way back to the first one. As soon as it find's a node with no parent it selects it and breaks out of the loop.

procedure TForm1.Button1Click(Sender: TObject);
var
  i:integer;
begin
  for i:=treeview1.items.count -1 downto 0 do
  begin
    if treeview1.items[i].parent=nil then
    begin
      treeview1.items[i].Selected:=true;
      break;
    end;

  end;
end;

Thanks nnbbb09, you answer gave me what i was looking for.

mohsenian, i was busy elsewhere and i think it rude of you that you assume that if someone does not respond back promptly they have rejected the answer.

hi moggy12,

sorry, you are right but I think 'rude' is not a good word for my action.

"obnoxious"...or do you have one in mind?

I hope you will give others a little more time before jumping on them.
