title: DataGrid binding to List<int?>
body: <p>I need suggestions on the best middle layer between the WPF DataGrid control and an underlying object of type <code>List&lt;int?&gt;</code> . Obviously I can't easily connect the two directly, as the DataGrid wants to bind to collection of objects with get/set properties, and I've had issues with the 'Value' property of a nullable int object not being found by a DataGrid column binding source.</p>
  
  <p>The original data source has to remain as a <code>List&lt;int?&gt;</code>, and I'm trying to leverage the auto add/delete/edit features that DataGrid gives you, so that the two-way data binding is persisted to the original <code>List&lt;int?&gt;</code> source.</p>
  
  <p>Thanks for any suggestions.</p>
