    Hi,

    I've implemented an appbar in each flipview which consists of a start and stop button. 

    What I want to do is that when the start button of an item is clicked for the very first time, 2 await methods are called. And if it is clicked for the second time onwards, it only calls 1 of the await method.

    For example, if I select an item and click the start button, the 2 await buttons are called successfully. However, when I navigate to the next item in the flipview or any other item, and click the start button, it is considered as a second click onwards despite me clicking a different item. 

    Thus, how can I implement it in such a way that the click count only applies to each individual item instead of the click count applies to all items as a whole?

    Thanks. 

    Regards,

    Eka

    Use a global boolean which all of the buttons set to true once when they are clicked. EX:

    public Boolean RunSecondAwaitMethod = true;

private async void Button_Click_1(object sender, RoutedEventArgs e)
{
  await AwaitableMethod();
  if (RunSecondAwaitMethod) await AwaitableMethod2();
  RunSecondAwaitMethod = false;
}

private void Button_Click_2(object sender, RoutedEventArgs e)
{
  await AwaitableMethod();
  if (RunSecondAwaitMethod) await AwaitableMethod2();
  RunSecondAwaitMethod = false;
}

private async Task<object> AwaitableMethod()
{
  // Do something           
}

private async Task<object> AwaitableMethod2()
{
  // Do something           
}

    NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
