title: WPF Binding syntax
body: <p>When to use "/" symbol in path?
  I thought "/" uses only when we work with XML, but today see example:</p>
  
  <pre><code>class ViewModel
  {
      CollectionView Data {get;set;}
  }
  
  class BusinessObkect
  {
      string Name {get;set;}
  }
  </code></pre>
  
  <p>DataContext property of the window is set to an instance of the ViewModel class, Data property of the ViewModel instance is niitialized with a collection of BusinessObject objects.</p>
  
  <p>if Text property of TextBox instance 
  <code>{Binding Path=Data/Name}</code> all works normal, but if <code>Text = {Binding Path=Data.Name}</code> - binding error.</p>
  
  <p>When I must use "/" instead of "." in bindings Path?</p>
