COM Objects > TracksBoard object > Methods > TracksBoard.ItemLockStateSet method

Remarks

Modifies the lock state of the given item. The current lock state can be modified through the TracksBoard.ItemLockStateGet method.

The full track can be locked through the TracksBoard.TrackLockStateSet method.

In case you should only need to lock the position of the item, allowing to continue modifying existing volume points and the amplitude line, the alternative would be the TracksBoard.ItemPositionLockStateSet method.
