Question

I have the following scenario:

the below 2 global variables in my page:

MainContext db = new MainContext();
User user = new User();

A method to fill the properties that is called on the button update:

private void FillProperties()
        {
            user.FirstName = txtFirstName.Text;
            user.LastName = txtLastName.Text;
            user.Email = txtEmail.Text;
        }

on the button update i am doing the following:

FillProperties();
user.ID = Request.QueryString("userid");
db.SaveChanges();

but the record isn’t been updated which i think is logical since the user variable isn’t related to db object, but i a, not being able to do this:

db.Users.AddObject(user);

since AddObject isn’t found in the db properties.

What can I do to update user?

Your answers are appreciated.

If you are using the DbContext API simply use

db.Entry(user).State = EntityState.Modified;
