1, page jump
In the control properties NavigateUri = "/ MainPage.xaml" settings need to jump page.
Or use this.NavigationService.Navigate (new new Uri ( "/ the MainPage .xaml", UriKind.Relative)); jump to the page.
2 Back
You may be used NavigationService.GoBack (); return to the previous page. Note that, before use judgment,
if (this.NavigationService.CanGoBack)
{
NavigationService.GoBack();
}
Previous avoided because there is no cause errors.
Learning, and if wrong supplement, hoping to point out, thank you ~ ~ ~ ~!
