Was trying to retrieve from the IWebPageContentQueryDataContainer's WebPageItemParentID (int), however it throws an exception if the content item has no parent (does not default to 0, the type is int not int?).
Likewise, the TryGetValue on that columns ALSO throws an exception, vs. returning "false" as you would expect from a try catch error.
