Good evening,
is it possible to prevent items from being dragged with the mouse into a PlannerControl?
Thanks for the replies

Hello

Try to use TPlannerControlEh.OnCheckPlannerItemInteractiveChanging event like this.

Code:
procedure TfrFrameOne.PlannerControlEh1CheckPlannerItemInteractiveChanging(
  PlannerControl: TPlannerControlEh; PlannerView: TCustomPlannerViewEh; Item,
  NewValuesItem: TPlannerDataItemEh; var ChangesAllowed: Boolean;
  var ErrorText: string);
begin
  ChangesAllowed := False;
end;
