Wait for the DisplayAlert to be closed

Question

Hi,

I have below code:

await App.Current.MainPage.DisplayAlert("Congratulations", "Your account is now active.", "Sign in");
App.Current.MainPage = new NavigationPage(new Signin());

The problem is that the code is immediately navigating to the Signin page although I have awaited the DisplayAltert.

I want the code to wait so the user will read the message and click on the DisplayAlert button.

Kidly help.

Thanks,

Jassim

Hello,

I want the code to wait so the user will read the message and click on the DisplayAlert button.

You can do this by Task.ContinueWith Method. And change the mainpage to Signin page, you need to run it on the Main thread, please refer to following code.

await App.Current.MainPage.DisplayAlert("Congratulations", "Your account is now active.", "Sign in").ContinueWith( (continueAction) =>
      {
         if (continueAction.IsCompleted)
          {
              MainThread.BeginInvokeOnMainThread(() =>
              {
                  // Code to run on the main thread
                  App.Current.MainPage = new NavigationPage(new Signin());
              });
          }      
      });

Best Regards,
