How Do I Access Parent From Usercontrol

Intro:
Ok, so i'm currently working in C# WPF, what i've got is a mainWindow and a number of different usercontrols, The mainWindow has got a grid of which it's children are having UserControls added and removed.

However i am wanting to be able to remove and add a different UserControl to this mainWindow grid from within the default (or first loaded) UserControl. e.g from a button click inside the UserControl, once clicked changes to a specific different UserControl and loads that in the mainWindow Grid.Children attribute.

I've tried:
Window parent = this.Parent;
Window parentWindow = Window.GetWindow(userControlReference);

public UserControl()<br />
{<br />
     InitializeComponent();<br />
     this.Loaded += new RoutedEventHandler(UserControl_Loaded);<br />
}<br />
<br />
public void UserControl_Loaded(object sender, RoutedEventArgs e)<br />
{<br />
      Window parentWindow = Window.GetWindow(this);<br />
      MessageBox.Show(parentWindow.ToString());<br />
}

The above i tried to see what it was returning and it returned the location reference of my mainWindow (ProjectTest.Loader.Views.MainWindow) however as it is only the location reference (atleast i think that's what it's called, correct me if i'm wrong) I'm unable to use any controls or properties from the actual window itself.

So what ways are there for me to access the Grid and or mainWindow from the UserControl child (Grid Child)

Thanks for any help :)
