title: Splitting WPF interface across multiple Xaml files
body: <p>I am trying to create a user interface using XAML. However, the file is quickly becoming very large and difficult to work with. What is the best way for splitting it across several files.</p>
  
  <p>I would like to be able to set the content of an element such as a ComboBox to an element that is defined in a different xaml file (but in the same VS project).</p>
  
  <p>thanks</p>
