    Hello Phu,

    I have created a sample with RadListView and its ItemTapped command and I cannot reproduce any issues while scrolling the ListView. 

    Let me explain in details: when item is swiped the ItemSwipeStarting event is triggered, then when you scroll the listvew the swiping is canceled. The ItemTapped command is triggered when you tap on the cell. If the swipe content is visible and the cell is tapped, the ItemTapped command is executed and then the item's swipe is canceled. 

    I have attached my test project for reference. Download it and give it a try.

    If you have any additional questions or concerns regarding this, please follow the next steps guide:

    Next Steps:

    - open a support ticket and attach a repro project there. Note that in the forum only image attachments are allowed

    - provide a "steps to reproduce" the issue

    - on which platform, device, emulator the issue occurs

    - versions of Xamarin.Forms and Telerik UI for Xamarin

    Also you could check our Feedback portal whether any of the logged RadListView issues matches the behavior you are observing.

    Could you please elaborate more in which ListView example from the Telerik UI for Xamarin Samples the issue can be reproduced?  Also in which iOS and Android versions the issue occurs?

    This bug can reproduce issues in app Telerik UI for Xamarin Samplese in List View Example Selection  at IOS 12+, Android 7+

    when I scroll the list up and down many times and quickly then swipe left or right quickly press the view of the item swipe then it won't receive the Command event in item view swipe left or right, this bug is frequency low.

    Hello Phu,

    Thank you for the provided details.

    I have tested the ListVeiw Selection example on Android 8.1 and iPhone X with iOS 13.2 and I could not reproduce the issue.

    I did the following steps:

    - quickly scroll the listview up and down
    - swipe listview's item
    - tap on item - expected - navigate to Detail's Page. ItemTapped event is triggered as expected.

    I have attached a video. Download it and review the steps. Let me know if I am missing something?

    Hello Phu,

    I have tested this scenario and the example runs as expected on my side. The ListView EndItemSwipe method works. Note that the Telerik UI for Xamarin ListView Selection example does not have any of the ItemSwipe events defined. 

    Next steps:

    As I could not reproduce the issue on our side, I would like to ask you to open a support ticket and attach a video of the issue, isolate repro project and the versions of Telerik and Xamarin.Forms used.

    Thank you for the understanding.
