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.

Useful Properties

You will probably use these properties most often:

PropertyDescription
CanVerticallyScrollDefines whether the content can be scrolled vertically.
CanHorizontallyScrollDefines whether the content can be scrolled horizontally.
