title: Bind DataGridTemplateColumn Visibility
body: <p>I am trying to bind the visibility of a column in a datagrid to a boolean DependencyProperty in the ViewModel (Set as data context of the View - UserControl in this case).
  For some reason (I don't seem to understand) it just doesn't work.</p>
  
  <p>After looking here I found out that the datagridtemplate (and any other template) is not part of the visual tree. So I can't bind to it.</p>
  
  <p>Any simple solution to the problem (without breaking the MVVM pattern of course) ?</p>
