I am on FirstPage and want to change to SecondPage by calling
await Navigation.PushAsync(new SecondPage());
But I always get an Exception. How do I navigate?
PushAsync is for use in a NavigationPage which handles Navigation for you. For this create your MainPage in your App class like this:
MainPage = new NavigationPage(new FirstPage());
Then you can use PushAsync.
If you don't want to use a NavigationPage for certain reasons, you should use
await Navigation.PushModalAsync(new SecondPage());
With this you have something like a two-dimensional navigation stack.
You need to set your First Page as your main page.
MainPage=new NavigationPage(new FirstPage());
And from the FirstPage you can go to the second page using a click event
btnTest.Clicked += async (sender, e) =>
{
await Navigation.PushAsync(new SecondPage());
};
