Automatically navigate to a new page after a time in UWP

Question

I'm trying to transition/navigate to a new page after a time (let's say 3 seconds), but nothing worked. I've tried this.Frame.Navigate(typeof(NewPage)); and it gives me an error "Object reference not set to an instance of an object.".

I've also tried

Thread.Sleep(3000); 
NewPage pg2 = new NewPage();
Window.Current.Content = pg2;

but it navigates immediately without waiting the 3 seconds.

The same problem I have also in am Xamarin app.

Answer 1

Thank you for your responses. In the mean time I've soled my problem and the code I'm using is the following:

await Task.Delay(3000);

Frame navigationFrame = Window.Current.Content as Frame;
navigationFrame.Navigate(typeof(PageToNavigateTo));

Answer 2

it gives me an error "Object reference not set to an instance of an object.

Please avoid use Thread.Sleep(3000), it will block UI thread and make Frame as null. And as Silent Programmer mentioned, you could use DispatcherTimer to approach.

var timer = new DispatcherTimer() { Interval = TimeSpan.FromSeconds(3) };
timer.Start();
timer.Tick += (s, e) =>
{
    Frame.Navigate(typeof(NewPage));
    timer.Stop();
};

Answer 3

you can try using DispatcherTimer , Dispatcher timer is having tick event, set timer from interval to one second.

write if in timer_tick event and when tickCount hits 3 , navigate to new page

Note : you may required to use coreDispatcher [If exception occures]

hope it help , if not work please comment down
