How can I pass parameter beetwen pages? I've tried to add parameters to page uri but it didn't work because I can't use onNavigatedTo event on user control. Please help
回答1:
You must use OnFragmentNavigation.
public void OnFragmentNavigation(FragmentNavigationEventArgs e)
{
DoYourStuff(e.Fragment)
}
e.Fragement contains everything past the # in the URI. In example, using
NavigationCommands.GoToPage.Execute("/Pages/CustomerPage.xaml#CustomerID=12345", this);
e.Fragment will be "CustomerID=12345"

It looks like you are coming from a client browser showing web pages world. With WPF you own the app! you can simply set the value on the new page before or after navigating, pass it in with a constructor or access it from a location accessible from both pages. It sounds like the parameter is an argument to the page so I would pass it in with a constructor in this case:
public class APage : Page
{
private object myVar; // use whatever Type you want
public APage
{
InitializeComponent();
}
public APage(object arg) : this()
{
this.myVar = args;
}
}
