Hi,

This is possible but will require some coding, If you take a look at the ContentImport.RecordImporting event you can cancel an import. So what you could do in this event is either update the old record. then cancel the import to make sure the new record doesn't get imported. Or you can use this event to delete the old record and import this new record as new.

The Items collection gives you all the fields from the record.  Using ContentRelation.GetRelatedDocument you can get the actual document based on the relation info. Below an example how to use the event to modify the document. It only requires a reference to the interface,businesslogic,cms and Umbraco dll's and the CMSImport.Extensions dll.

    public class SetUnpublish : ApplicationBase
    {
        public SetUnpublish()
        {
            ContentImport.RecordImporting += new ContentImport.RecordImportingEventHandler(ContentImport_RecordImporting);
        }

        void ContentImport_RecordImporting(object sender, RecordImportingEventArgs e)
        {
            //Add an extra day, you might check if teh value is null or not
            ((DateTime)e.Items["ClosingDate"]).AddDays(1);
        }
    }

Is this something that you are after?

Thanks,

Richard

It looks like it might be. 

Do you mean doing something like this.  Manually setting the values of the document and cancelling the actual import.

void ContentImport_RecordImporting(object sender, RecordImportingEventArgs e)
{
    Document d = ContentRelation.GetRelatedDocument(e.DataAdapter, e.DataKeyName, e.Items["Old Course Code"]);
    d.getProperty("courseCode").Value = e.Items["Course Code"];

    e.Cancel = true;
}

This seems to be working however even though I am cancelling the import a new document is still being created, although no data is being filled into the properties.

Is there something I need to set to stop this from happening.

is working on a reply...
