title: WPF Binding individual text boxes to an element in a collection object or array
body: <p>I need to bind a <code>textblock.text</code> property to a single element in an observable collection, or array element, and have the text update using the <code>INotifyPropertyChanged</code> or <code>INotifyCollectionChanged</code>, whichever is best.</p>
  
  <p>Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.</p>
  
  <pre><code>textblock1.Text = MyArray(0)...
  textblock2.Text = MyArray(1)...
  textblock3.Text = MyArray(2)...
  textblock4.Text = MyArray(3)...
  etc...
  </code></pre>
  
  <p>Is it possible to bind a single textblock to a single array element?</p>
  
  <p>Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?</p>
