title: Datacontext reset at c#
body: <p>My WP app can edit data from database, which I get using LINQ query:</p>
  
  <pre><code>from item in db.SomeTable
  where item.Id = 5
  select new { Item = item}
  </code></pre>
  
  <p>And then I bind that selection to form controls.
  When I don't want to save changes (no <code>db.SubmitChanges()</code> call), I call another LINQ to reset field, but I get changed source values from db (even when I'm using <code>select new {}</code> operator.
  If there any way to reset to default state, so that I can get default values using LINQ again?</p>
