The example is an event handler for the Button1 button.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Begin
    treelist1.Nodes.BeginUpdate;
    treelist1.nodes.FirstNode.Accessibility := False;
    treelist1.nodes.FirstNode.NextNode.Accessibility := False;
    treelist1.Nodes.EndUpdate;
End Sub Button1OnClick;

After executing the example, element and subelement will be inactive in the TreeList component.
