title: Binding StringFormat
body: <p>I have a collection of textblocks that I'm going to be showing and I'm needing the text of each textblock to be displayed differently. I'm currently saving the format string in the tag property and I'm needing to display the text in this format. How do I bind the StringFormat section?</p>
  
  <p>Something like the section below:</p>
  
  <p><code>&lt;TextBlock Tag="{Binding MyFormatString}" Text="{Binding MyProperty, StringFormat='{}{0:MyTag}'}" /&gt;</code></p>
