title: Simple Master/Detail scenario with combobox/datagrid in Silverlight 4
body: <p>I'm building a series of admin forms as part of my application.</p>
  
  <p>Many of the forms have this same scenario, and I'm wondering what the best way to manage this is...</p>
  
  <p><a href="http://gyazo.com/6cc16dbb76f831fc382c7721d71fdde2.png" rel="nofollow">Here's a screenshot of an example from the old winforms app.</a> Not all of the forms are this simple, but I figure it's a good place to start. </p>
  
  <p>The first field is always a combo box. After a user selects an item, the other fields populate with the associated data. </p>
  
  <p>Currently, my ViewModel contains an <code>ObservableCollection&lt;circuit&gt;</code> (for this example). I'm not sure how to set up my bindings, given the master/detail scenario where your master (primary combobox) is also part of your detail (CircuitName field). I was thinking of pulling the combobox out and, after selecting an item, displaying a datagrid. Is there a better way? If I do go this route, I have read a few articles that indicate binding a combobox INSIDE the datagrid, while property binding the selectedValue prop is a total PITA. Obviously having a combobox would be required for a user to create/edit an existing CircuitName...</p>
  
  <p>Your thoughts?</p>
