MVC Edit method resets field to default value

I have a Customer Model containing the following properties: Id, Name and AccountBalance.

A Customer can register an account, but is not able to specify his AccountBalance (I didn't include it in the create method parameter

    public ActionResult Create([Bind(Include="Id,Name")] Customer customer)

I added a HiddenFor in the View method:

    @Html.HiddenFor(model => model.AccountBalance)

This all works fine, the customer can create an account and the accountbalance defaults to 0.

The problem occurs when editing the customer's account. I don't want the customer to be able to edit his accountbalance, so I also omitted it from the edit method and added a hiddenfor in the edit method's view. When I edit a customer's name for instance, the AccountBalance resets to 0.

How do I deny the user from changing the AccountBalance, but have MVC not reset the value to 0?

Thanks in advance.

Stephen Muecke's first suggestion works for me. Didn't try the second one yet.

On your Controller:

public ActionResult Edit([Bind(Include="Id,Name,AccountBalance")] Customer customer)

Then on your View:

@Html.HiddenFor(model => model.AccountBalance)

Hope this helps and works for others! :)

Ended up solving it with Stephen Meucke's suggestion:

    var original = db.Customers.FirstOrDefault(x => x.Id == customer.Id);
    customer.AccountBalance= original.AccountBalance;

    db.Entry(original).CurrentValues.SetValues(customer);

    db.SaveChanges();

Thanks a lot!
