title: WPF Toolkit Datagrid Headers and Empty Source
body: <p>How could I make the Datagrid display the headers in case there's no row to display?</p>
  
  <p>My Datagrid is "completely" read-only with:</p>
  
  <p>"AutoGenerateColumns ="True"
  "CanUserAddRows="False"
  "CanUserDeleteRows="False"
  "CanUserResizeRows="False"
  "IsReadOnly"="True"</p>
  
  <p>If there's no row, then the headers aren't displayed, if I add even an empty row, then the headers are shown!</p>
  
  <p>Until now, I couldn't find any workaround/solution for that!</p>
  
  <p>Thx all</p>
