How do you switch between two different Xamarin Form pages? - xamarin

Question

I'm trying to figure out how to switch between two different pages in Xamarin Forms.
I do not wish to use a NavigationPage (which has that little back arrow that is auto displayed.
I have a Login page (which is a ContentPage) and once the person has authenticated, I then need to navigate to my Dashboard page (which is a TabbedPage).
eg.
Next, one of the Tab's in the TabbedPage is the profile of the logged in user. As such, I need to log them out. So i'll have a button to log them out, which means I will need to navigate them back to the Login page (which was that ContentPage).
I feel like I have two modes the user might be in.
UnAuthorized. (ContentPage)
Authorized. (TabbedPage).
It's like I need to change the App's MainPage to be either one of those two?

Answer 1

To change MainPage to another just do:
App.Current.MainPage = new NavigationPage(new MyContentPage());
or
App.Current.MainPage = new MyContentPage();
BTW: You can use a NavigationPage and then HIDE the toolbar with:
NavigationPage.SetHasNavigationBar(this, false);

Answer 2

You can do navigation as usual by setting MainPage in your Application instance. Small sample.
namespace TestNavigation
{
public class App : Application
{
public App ()
{
// The root page of your application
MainPage = new MyPage1 ();
}
}
}
namespace TestNavigation
{
public class MyPage1 : ContentPage
{
public MyPage1 ()
{
var button = new Button () {
Text = "Click me"
};
button.Clicked += (object sender, EventArgs e) => {
Application.Current.MainPage = new MyPage2 ();
};
Content = new StackLayout {
Children = {
button
}
};
}
}
}
namespace TestNavigation
{
public class MyPage2 : ContentPage
{
public MyPage2 ()
{
Content = new StackLayout {
Children = {
new Label { Text = "Hello ContentPage" }
}
};
}
}
}

I submitted this answer but then I realised that I probably don't understand your problem.

Updated sample.

If you like to switch between the pages then you can simply do
Application.Current.MainPage=new YourPage();

Answer 4

For a login page, the best practice is to use
await Navigation.PushModalAsync (new LoginPage());
Once you are on the LoginPage, you can use popModelAsync after the validation is passed:
await Navigation.PopModalAsync ();
