I am using the position() function to display the position in which each row in a repeating table is located in the XML. This is being shown to the user using an Expression Box next to each row.

How can I display that position in the screentip of an error (from Data Validation) and/or in the error generated by using the e.ReportError() method.

Thank you.

I don't believe that validation rules allow for dynamic messages, so that wouldn't be an option.

In code, probably the easiest way to get a field's position is something like.

XPathNodeIterator previousRows = e.Site.Select("../preceding-sibling::my:repeatingGroup", NamespaceManager);

int position = previousRows.Count + 1;

You may need to add or remove ../s to the path depending on the relative path from e.Site to the repeating group.
