Hi
DefaultNodeExpanded:=false work fine but DefaultNodeExpanded:=true not.

This is my code :

if tmp_box.Enabled then tmp_memE.TreeList.DefaultNodeExpanded:=false

else tmp_memE.TreeList.DefaultNodeExpanded:=true;

tnp_memE.Refresh;

Hello

Please, check result in <EhLib Archive>\Demos\DBGridEh.TreeView\Project1.dpr project.

Code:
procedure TForm1.Button2Click(Sender: TObject);
begin
  if (DBCheckBoxEh1.Checked)
    then MemTableEh1.TreeList.DefaultNodeExpanded := True
    else MemTableEh1.TreeList.DefaultNodeExpanded := False;

  MemTableEh1.Refresh;
end;


I tested it. I works as for DefaultNodeExpanded := True as for DefaultNodeExpanded := False.

Hello

Can you use TreeList.FullExpand and TreeList.FullCollapse code instead of DefaultNodeExpanded?

Like this:

Code:
  if (DBCheckBoxEh1.Checked)
    then MemTableEh1.TreeList.FullExpand
    else MemTableEh1.TreeList.FullCollapse;
