Method “TreeList.MoveNode” does not transfer the node?
Data source - MS Access database;
Scenario.
- form "Frm6UC". The user selects the node to be transferred;
- form "Frm6UC". User clicks "button1";
- form "searchNodefrm". User chooses where to move;
- form "searchNodefrm". The user clicks "button2" (Select);
- result. See picture.
Question.
How to make the "TreeList.MoveNode" method work?
