How do we detect double tap/click on a button in UWP?

Question

Hello everyone, i have a button in my UWP app. If one time clicked/tapped i want it to perform some operation and if double clicked/tapped, it should perform other operation. How do i do this?

I know, there are some similar queries in this forum, but i felt those are not comprehensive enough. So i've created this question.

Please answer asap and keep things in detail.

Hello,

Welcome to Microsoft Q&A!

The button object has a DoubleTapped Event which will occur when the user double-taps the button. You could handle that event for your logic.

One thing you need to notice is that, If you want different logic for Tapped versus DoubleTapped, your Tapped handler may need to use app-specific variables and a timer in order to avoid running on interactions that are eventually interpreted as a DoubleTap action. This is mentioned in the official document here: UIElement.DoubleTapped Event Remarks.

So what you need to do looks like this:

 <Button Content="Click" Tapped="MyButton_Tapped" IsDoubleTapEnabled="True" DoubleTapped="MyButton_DoubleTapped" Name="MyButton"/>  

Code-behind:

  public bool IsSingleTap;  
  
        private void MyButton_DoubleTapped(object sender, DoubleTappedRoutedEventArgs e)  
        {  
            IsSingleTap = false;  
  
            Debug.WriteLine("MyButton_DoubleTapped");  
        }  
  
        private async void MyButton_Tapped(object sender, TappedRoutedEventArgs e)  
        {  
            IsSingleTap = true;  
            await Task.Delay(200);  
            if (IsSingleTap)  
            {  
  
                Debug.WriteLine("MyButton_Tapped");  
            }  
  
             
        }  

Thank you.
