ScrollGestureRecognizer

A gesture recognizer that tracks a scrolling gesture. This can be attached to a control to detect when a pointer moves in a specific direction inside the control's bounds. This is especially useful when a control pans its contents, either horizontally, vertically or both.

Using a ScrollGestureRecognizer

A ScrollGestureRecognizer can be attached to a control using the control's GestureRecognizers property.

<Image Stretch="UniformToFill"
        Margin="5"
        Name="image"
        Source="/image.jpg">
  <Image.GestureRecognizers>
    <ScrollGestureRecognizer CanHorizontallyScroll="True"
                              CanVerticallyScroll="True"/>
  </Image.GestureRecognizers>
</Image>

C#

image.GestureRecognizers.Add(new ScrollGestureRecognizer()
            {
                CanVerticallyScroll = true,
                CanHorizontallyScroll = true,
            });

The ScrollGestureRegonizer raises a Gestures.ScrollGestureEvent when it detects the start of a scroll gesture. When the scroll ends, from the pointer being released or another gesture start, it raises a Gestures.ScrollGestureEndedEvent.
