Linq To SQL Attach/Refresh Entity Object

Question

In Linq To Sql, when updating one of my entities, Faculty, I am creating a new instance of the Faculty object, then initializing some of the properties with values supplied by the user.

If I attach this new object to the entity set, and submit changes, the properties that I didn't set take on the default value of whatever datatype they are.

How can I refresh the new object so that the properties that have been set keep their values and the properties that haven't been set get the values from the database?

Thanks

Answer 1

What about retrieving the object from the database, then changing the appropriate values, then submitting the update?

Answer 2

Did you try

context.Refresh(RefreshMode.OverwriteCurrentValues, faculty);

after submit changes where context is your linq2sql datacontext and faculty is the entity you want to refresh?
