Hi
Thanks for your inquiry. This occurs because current field is not placed in table. So GetAncestor(NodeType.Row) returns null. You should use the following code:

void MailMerge_MergeField264(object sender, MergeFieldEventArgs e)
{
    if (string.IsNullOrEmpty(e.FieldValue.ToString()))
    {
        Aspose.Words.Node parentRow = e.Field.Start.GetAncestor(NodeType.Row);
        if (parentRow != null)
            parentRow.Remove();
    }
}

Hope this helps.
Best regards.

Hi
Have you tried to use the template I attached in the following thread?

I think this should solve your problem.
