Хотя этот пример немного сложны для понимания и для использования, нужно придумать более лояльный метод...

Переделал полностью пример, теперь должно быть яснее - Для каждого TreeViewItem'а выделен блок (через #Region), в границах этого блока, !!!до «$i*_Last_Item = GUICtrlCreateDummy()», можно помещать новые элементы, они будут попадать под процесс отображения/скрытия элементов.
