title: Convert IQueryable to BindingList
body: <p>Placing <code>ObsevableCollection User</code> from DataSource as Details on new form it creates all textBoxes, BindingSource and BindingNavigator. Which is excelent and fast.</p>
  
  <p>Because I only need to update one user I removed BindingNavigator. But... </p>
  
  <p>Can this be without a conversion of lists?</p>
  
  <pre><code>class UserDt : Forms {
      // Designer partial part
      this.userBindingSource.DataSource = typeof(WinFormswithEFSample.User);
  
      private void UserDt_Load
      {
          _context.Users.Load();
  
          // use this with BindNavigator to navigate ower all users
          //this.userBindingSource.DataSource = _context.Users.Local.ToBindingList();
  
          // this doesn't work
          //this.userBindingSource.DataSource = _context.Users.Where(p =&gt; p.Username == "admin").Local.ToBindingList();
  
          var query = _context.Users.Where(p =&gt; p.Username == "admin").ToList();
          var binding = new BindingList&lt;User&gt;(query);
          this.usersBindingSource.DataSource = binding;
      }
  }
  </code></pre>
