1. Passing a string value using formatted string:
The easiest way to pass a parameter is just to use a string, something like:
private void btnNavigate_Click(object sender, RoutedEventArgs e) {
NavigationService.Navigate(new Uri("/Page1.xaml?parameter=test", UriKind.Relative));
}
2. Passing multiple parameters.
private void btnNavigate_Click(object sender, RoutedEventArgs e) {
NavigationService.Navigate(new Uri("/Page1.xaml?parameter1=p1&meter2=p2", UriKind.Relative)); }
