Default protection for new shapes in a document

Hello,

As it is possible to set default styles for shapes using NDrawingDocument.Style attribute, is it possible to define default protections for the shapes we are drawing?

Maybe I could use one of the event in the EventSinkService to know when a new shape is added and set the protections at this point?

Thanks

Found one answer for doing this:

document.EventSinkService.NodeInserted += new ChildNodeEventHandler(EventSinkService_NodeInserted);

and

void EventSinkService_NodeInserted(NChildNodeEventArgs args)
{
INNode child = args.Child;

if (child is NRoutableConnector && child as NRoutableConnector != null)
{//we just added a connector
NRoutableConnector edge = child as NRoutableConnector;
NAbilities protection = new NAbilities();
protection.MoveX = true;
protection.MoveY = true;
edge.Protection = protection;
}
}

Hi, in your case it is best to apply the protections when the shape is added to the doucment, i.e. in the NodeInserted event of the document's event sync service:

document.EventSinkService.NodeInserted += OnNodeInserted;

 

private void OnNodeInserted(NChildNodeEventArgs args)

{

      NShape shape = args.Child as NShape;

      if (shape == null)

            return;

 

      // Set protections

      NAbilities protection = shape.Protection;

      protection.Select = true;

      shape.Protection = protection;

}
