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; |
