title: Can I Achieve this Layout in Xaml?
body: <p>I have an array of objects that is basically a grid of Ids/Values for various Categories.  If I bind the collection ordered by category can I bind a "grid" of textboxes in a ListView? The ID values will be known. Example to clarify below. I can handle the UI, but I can't figure out how to "place" by the ID but show/bind the value unless I punt and create the UI in the code-behind.</p>
  
  <pre><code>public class MyItem {        
     string ID;
     string Value;
     string Category;
  }
  
  with values: 
    { id1,  value1a, catA}
    { id2, value1b, catA}
    { id1,  value2a, catB}
    { id2, value2a, catB}
  </code></pre>
  
  <p>Desired UI binding (ListView with each row showing values of each category):</p>
  
  <pre><code>value1a       value1b
  value2a       value2b
  </code></pre>
