  • Hello SmartWhy,

    Welcome to the Developing Universal Windows apps forum! 
    Please read the sticky posts, especially the Guide to posting: subject line tags and Known Issues for Windows 10 SDK and Tools .

    If you are using your own Slider class then you may need to see drag related event, for example:


    For more details please tell us more things about your project. Now I can only see that you are showing WPF articles. I'm not so sure about your really problem.

    By the way, I recommend that you can check Slider class to see more details about any available events.

    (PS: In Slider we can see that there are also Point enter and Point leave, this is also the event that you can used)

    Best regards,
