Since we’re not talking data access – upon postback, compare it to your object in your database. This is somewhat of an open question because it depends what data access you are using and what models you are using. Entity framework Entities can track their modified state so you may be able to use
and check the status of each field. That ‘may’ work, otherwise you are comparing each field. However why do you need to know specifically which field changed? Save the entire object back to the database (or simply merge with the values from the page using the same TryUpdateModel above)
