title: WPF DataGrid Binding
body: <p>I'm using the WPF toolkit datagrid and in the past have always created entities for the grid to bind to, so for example a Contact Entity with Name, Address etc. 
  On the current app I'm working on the user may select from 50 tables and individually select the fields from the tables to generate a view. 
  Clearly here having an Entity to bind to will not work as the binding source will be dynamic.</p>
  
  <p>Question is what do I do?</p>
  
  <p>Thanks</p>
