Hi i am trying to update a record from the database, but for some reason the record is not updated. I am using ADO.NET entity Framework 4.0
public void updateCredits(string username)
{
myDBEntities Entity = new myDBEntities();
User u = Entity.Users.SingleOrDefault(u => u.username == username)
u.firstname = "name";
u.credits = 11.5;
Entity.SaveChanges();
}
I tried restarting VS and even the SQL Server but no luck. Am i doing something wrong?
It looks like there is an issue with change tracking. You can try manually marking the User
entity as changed like so:
public void updateCredits(string username)
{
myDBEntities Entity = new myDBEntities();
User u = Entity.Users.SingleOrDefault(u => u.username == username)
u.firstname = "name";
u.credits = 11.5;
Entity.Entry(u).State = EntityState.Modified; //<-- manually indicate the entity was changed
Entity.SaveChanges();
}
If the above code works, then there's a good chance ChangeTracking is being disabled somehow.
