Pages versus Windows

Question

I have a RibbonWindow as start window and now I want to create an input option for persons, articles etc.

 

 

If I use further windows they will all open as new windows.

 

Since not so many controls are needed, I wanted to use pages that are displayed in the RibbonWindow.

Therefore I have the following entry in the RibbonWindow

<Frame x:Name="WorkZone" Grid.Row="2" Grid.RowSpan="2" NavigationUIVisibility="Hidden"></Frame>

In the CodeBehind the page is displayed with

 

private void BtnLief_Click(object sender, RoutedEventArgs e)
        {
            WorkZone.NavigationService.Navigate(new Uri("PageRSTGruppen.xaml", UriKind.Relative));
        }

 

This works. 

When I click on Close the page should be closed.

 

 

 

 

 

 

 

Problem is, there is no "Close()" option in the page.

 

How can I remove the page from the RibbonWindow or where can I find an example?

Maybe this is not a good approach with pages and I should work with windows?

 

Thanks a lot
