@seba30 Thx for the code. I can see that you use a FlipViewItem inside a FlipViewItem ;-) because the FlipViewItem is automatically generated by WPF itself, so you don't need to use a second one.
So my suggestion and maybe the easiest way is to use a Binding to the BannerText of the FlipView and the SelectedItem like
BannerText="{Binding RelativeSource={RelativeSource Self}, Path=SelectedItem.Title, FallbackValue={x:Null}}"and then using this ItemTemplate
<mah:FlipView.ItemTemplate>
<DataTemplate DataType="interfaces:IPage">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="30" />
</Grid.RowDefinitions>
<ContentControl Grid.Row="0" cm:View.Model="{Binding}" />
</Grid>
</DataTemplate>
</mah:FlipView.ItemTemplate>

Does anyone know if it's possible to change the underlying XAML definition of BaseMetroDialog?
I have a custom style for dialog boxes, but I need to change the highlighted line below - since it's in BaseMetroDialog.xaml, I'm not sure how to go about it:
System.InvalidOperationException: 'Context is not registered. Consider using DialogParticipation.Register in XAML to bind in the DataContext.' _dialogCoordinator.HideMetroDialogAsync(Application.Current.MainWindow as MetroWindow, Dialog);<mah:MetroWindow
mah:DialogParticipation.Register="{Binding}"
...
