PnId Database Overrule

annse — Fri, 31 May 2013 08:02:14 GMT

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.
