How correct set PropertyPath

How correct add PropertyPath ?

I need binding usercontrol DataContext to DataContext, TwoWay.

                          {
                              Mode = BindingMode.TwoWay,
                              Source = ((FrameworkElement)sender),
                              Path = new PropertyPath(FrameworkElement.DataContextProperty)
                          };
    binding.Source = ((FrameworkElement) sender);

PropertyPath has a string consructor, which takes the property path as follows:

  var binding = new Binding()
                {
                   Mode = BindingMode.TwoWay,
                   Source = ((FrameworkElement)sender),
                   Path = new PropertyPath("DataContext")
                };

Alternatively, Binding has a constructor which will create a PropertyPath from the gives string argument:

  var binding = new Binding("DataContext")
                {
                   Mode = BindingMode.TwoWay,
                   Source = ((FrameworkElement)sender)
                };

binding.Path = new PropertyPath("DataContext")

Also it would help if you will say what is wrong with your code.
