Key Points:

 

1. Make sure that you have already added the assembly System.windows.Controls.Navigation in you project.

2. import the namespace xmlns:navigation="clr-namespace:System.windows.Controls;assembly=System.windows.Controls.Navigation"

3. There are two main items here.

    navigation:Frame  this can hold the pages and controls

    navigation:Page

4. <navigation:Frame x:name="MainFrame" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch" margin="20" UriMapper="{StaticResource uriMapper}"
                           Source="About">
         </navigation:Frame>

 

-- Source it to set the default URI for the frame.

--UriMapper is to set the UriMapper defined in the app.xaml<Application.Resources> <navcore:UriMapper x:Key="uriMapper"> <navcore:UriMapPing Uri="Home" MappedUri="/VIEws/HomePage.xaml" /> <navcore:UriMapPing Uri="About" MappedUri="/VIEws/AboutPage.xaml" /> <navcore:UriMapPing Uri="Customers" MappedUri="/VIEws/CustomersPage.xaml" /> <navcore:UriMapPing Uri="Customer/{ID}" MappedUri="/VIEws/CustomerDetail.xaml?ID={ID}" /> </navcore:UriMapper> </Application.Resources>

 

5. You can use the Navigate method of the Frame to go to where you want to. Before doing this,you should add some Hyperlinkbutton controls outsIDe the Frame

 

Hyperlinkbutton btn = sender as Hyperlinkbutton; string url = btn.Tag.ToString(); MainFrame.Navigate(new Uri(url,UriKind.relative));

 

6. If you want to Navigate another page when you are insIDe the page,you Could use this.NavigationService.Navigate(new Uri(string.Format("Customer/{0}",ID),UriKind.relative));
