If undo is enabled (UndoLimit<>0), the editor hides the control ("moves" it

to undo buffer).

The control is not destroyed yet and can be returned by redo operation.

If the size of undo buffer is limited (UndoLimit is positive), the control

can be destroyed in the undo buffer when the number of stored operations

exceeds the limit.

Can you explain what do you want to achieve?
