<PasswordBox x:Name="MyPWBox1" Margin="20,10,0,0" PasswordChanged="MyPWBox1_PasswordChanged" MaxLength="8" Height="35" Width="200" HorizontalAlignment="Left" />
<TextBlock Text="Password" Margin="20,10,0,0"/>
<TextBox x:Name="ReadOnlyTB" Margin="20,10,0,0" HorizontalAlignment="Left" IsReadOnly="True" Height="35" Width="200" />

'Displaying the password typed in MyPWBox1 in ReadOnlyTB
Private Sub MyPWBox1_PasswordChanged(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ReadOnlyTB.Text = MyPWBox1.Password
End Sub
