title: Check validation errors for all bindings bound to current DataContext
body: <p>I have a form with some controls (say TextBox) which Text property is bound to some DataContext (say DataRowView).</p>
  
  <p>I want to know if this row was filled correctly without any validation errors. <a href="https://stackoverflow.com/questions/127477/detecting-wpf-validation-errors">I have found one possible solution.</a> But I do not like it. It is not good to enum all the DependencyObjects on a form. Is there any way to enum only those DependencyObjects which was bound to this DataContext? May be some magic with BindingOperations...</p>
