title: WPF - Can StringFormat be bound to a property?
body: <p>Given a WPF text box, as an example:</p>
  
  <pre><code>&lt;TextBox Text="{Binding Path=blahProperty, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, StringFormat=\{0:yyyy.MM.dd HH:mm:ss\}}"/&gt;
  </code></pre>
  
  <p>Could the StringFormat I've got there instead be bound to an underlying property string? - i.e. could the "yyyy.MM.dd HH:mm:ss" be provided by a property on the View (or ViewModel) instead of being hard-coded in the xaml?</p>
