That is doable as long as you’re handling a proper
PropertyChangedevent for this type.Aside, I would not recommend doing so, since this would necessitate to keep the connection alive until the whole editing is made, that is, one trip around the database for each property that has changed along the edit.
Should you want not to keep the connection, that will cost even more, since you’ll have all the connection instantiation and opening overhead, yet your database engine might manage a connection pool for itself.
ADO.NET prefers an offline approach, I don’t remember the term exactly. That is, connect to the database to load the needed data, and close and dispose it afterwards, so that another user may use the connection. Meanwhile, on your side, the user brings the changes he needs, then when he’s done, he persists them into the database, and then only one trip around the database is required for a bunch of changes, which looks to me to be more productive and more performant.
