Is it possible to pop a modal page and then immediately push a new one?

Issue

I have tried this but it does not work

    private async void SignUpLink_OnTapped(object sender, EventArgs e)
      {
        await Navigation.PopModalAsync();
        await Navigation.PushModalAsync(new SignUp());
      }

Solution

It is possible . You can use delegate to realzie it .I will show a sample with MainPage/SecondPage/ThirdPage to show it.

Define a delegate in PageA and method to invoke it :

public partial class MainPage : ContentPage
{
    //declare a delegate in MainPage
    public delegate void MyDelegate(bool val);

    public MainPage()
    {
        InitializeComponent();
    }

    async private void Button_Clicked(object sender, EventArgs e)
    {
        // navigate to second page with delegate
        await Navigation.PushModalAsync(new SecondPage(DeleagteVoid));
    }

    // invoked by poping back
    private async void DeleagteVoid (bool value)
    {
        //When delegate method invoked , by value to determine whether to push to next page
        Console.WriteLine("---" + value);
        if (value)
        {
           // if true , push to third page 
           await Navigation.PushModalAsync(new ThirdPage());
        }
    }

}

SecondPage when poping to previous page invoke delegate method which in MainPage :

public partial class SecondPage : ContentPage
{
    // declare delegate also in second page
    MyDelegate myDelegate;

    public SecondPage(MyDelegate deleagteVoid)
    {
        InitializeComponent();
        // assign delegate
        this.myDelegate = deleagteVoid;
    }


    private async void Button_Clicked(object sender, EventArgs e)
    {
        // pop to previous page
        await Navigation.PopModalAsync();
        //invoke delegate method in MainPage
        myDelegate(true);
    }
}

ThirdPage do other you want .
