Xamarin navigation (current page)

I'm developing an application using xamarin forms , I have to check the connectivity , i'm using the connectivity plugin .

So , what I want , if there is no connection , I want to go to no navigation page , and after the navigation is back , I want to go back to the page where I was .

What I was able to do is , to go back to the main page of the application , doing this on my App.xaml.cs .

Is there any way I can go back to the page where Exactly I was ?!

 

public App()

{

InitializeComp*onent();

if (Device.Idiom == TargetIdiom.Tablet || Device.Idiom == TargetIdiom.Desktop)

MainPage = CrossConnectivity.Current.IsConnected ? (Page)new NavigationPage(new ClientPagetablet()) : new NoNetworkPage();

else

MainPage = CrossConnectivity.Current.IsConnected ? (Page)new NavigationPage(new ClientPage()) : new NoNetworkPage();

}

private void HandleConnectivityChanged(object sender, ConnectivityChangedEventArgs e)

{

Type CurrentPage = this.MainPage.GetType();

if (e.IsConnected && CurrentPage != typeof(ClientPage))

this.MainPage = new NavigationPage(new ClientPage());

else

if (!e.IsConnected && CurrentPage != typeof(NoNetworkPage))

this.MainPage = new NavigationPage(new NoNetworkPage());

}

protected override void OnStart()

{

// if there is no connectivity it's going to go to no network page

base.OnStart();

CrossConnectivity.Current.ConnectivityChanged += HandleConnectivityChanged;
