title: How to update my gridView.ItemsSource in C#
body: <p>I have a problem with a <code>GridView</code> and the <code>ItemsSource</code></p>
  
  <p>My Code looks like this:</p>
  
  <pre><code>public ObservableCollection&lt;MyClass&gt; MyData = new ObservableCollection&lt;MyClass&gt;();
  ...
  gridView.ItemsSource = MyData;
  </code></pre>
  
  <p>when I add something to <code>MyData</code> I instantly see it in the grid. But when I edit a element of the type <code>MyClass</code> in <code>MyData</code> I dont see the changes in the grid.</p>
  
  <p>How to refresh the grid so I also see the changes made on on <code>MyClass</code> item?</p>
