How would one go about setting the logged in user for a readonly UI field as a default. I have .net membership running. Is there a way of retrieving a session variable of some sort that can be used for Inserts and updates. I would like to log the last user who edited a record.Each table has a [LastUser] Column that needs to be populated.
