PnId Database Overrule

[annse]

Hi!

Does anyone know if there is an equivalent ObjectOverrule for the PnId Database?

If an entity is copied I dont want certain field values to be copied.

I've tried an ObjectOverrule but I can't get the RowId at that point.

I also noticed that the field values are set as XData. I edited the XData in my ObjectOverrule but the values still gets copied.

Is there a setting at project level to control which fields not to copy?

Thanks!

ObjectOverrule should apply to P&ID entities like all other entities. I am not sure off hand the exact order of events between our cloning code and the overrules. I do know we react to begin/end clone events and in the end clone do a lot of work to create rows in the project database, establish relationships, and copy row data.

I don’t think the Xdata is used in all situations. I know we attach Xdata with the property data so that we can insert DWGs (e.g. wblock followed by insert / explode).

It seems you simply want to prevent some project database row data from being copied?

I believe the best way to do that is to use the DataLinksManager events. 

        static private bool bIsActive = true;

        public static void dlm_DataLinkOperationOccurred(object sender, DataLinkEventArgs e)

        {

            if (e.Action == DataLinkAction.RowModified && bIsActive)

            {

                try

                {

                    DataLinksManager dlm = PlantProject.ActiveProjectPart.DataLinksManager;

                    if (dlm.HasProperty(e.RowId, "SAPCode"))

                    {

                        StringCollection props = new StringCollection();

                        props.Add("Size");

                        props.Add("Spec");

                        StringCollection values = null;

                        values = dlm.GetProperties(e.RowId, props, true);

                        PpObjectIdArray ppoids = dlm.FindAcPpObjectIds(e.RowId);

                        StringCollection newprops = new StringCollection();

                        newprops.Add("SAPCode");

                        StringCollection newvals = new StringCollection();

                        newvals.Add(values[0] + values[1]);

                        bIsActive = false;

                        dlm.SetProperties(ppoids.First.Value, newprops, newvals);

                    }

                }

                catch

                {

                }

                finally

                {

                    bIsActive = true;

                }

            }

        }

        [CommandMethod("DEMOSTART", CommandFlags.Modal)]

        public static void DemoStart()

        {

            DataLinksManager dlm = PlantProject.ActiveProjectPart.DataLinksManager;

            dlm.DataLinkOperationOccurred +=new DataLinkEventHandler(dlm_DataLinkOperationOccurred);

        }

        [CommandMethod("DEMOEND", CommandFlags.Modal)]

        public static void DemoEnd()

        {

            DataLinksManager dlm = PlantProject.ActiveProjectPart.DataLinksManager;

            dlm.DataLinkOperationOccurred -= new DataLinkEventHandler(dlm_DataLinkOperationOccurred);

        }

That is sample code that updates a SAPCode property every time a row in the project is modified. It would need to be changed to react to rows being added / modified and blank out necessary properties.
