title: Filter items of a ListBox based on the text of a TextBox using only XAML in WPF
body: <p>I currently have a ListBox binded to a collection of items. As the collection is big we want to filter the items being shown based on the text entered on a TextBox. </p>
  
  <p>What I'm asking is if this is possible to implement using only XAML, I don't want to modify the collection of items, I would like to modify the Visibility of each of the items based on the filter.</p>
  
  <p>Hope its clear,</p>
  
  <p>thanks!</p>
