title: how to set binding stringformat to all DataGridTextColumn controls?
body: <p>This is one of my DataGridTextColumn controls looks like :</p>
  
  <pre><code>&lt;DataGridTextColumn x:Name="contractStartDateColumn" Header="Start Date" Binding="{Binding Path=StartDate, StringFormat={}\{0:dd/MM/yyyy\}}" /&gt;
  </code></pre>
  
  <p>Then how can I set <strong>StringFormat={}{0:dd/MM/yyyy}</strong> to all of DataGridTextColumn controls instead of setting every single one ?</p>
