The collection of gesture recognizers associated with this view.

Remarks
Adding items to this collection will associate gesture events with this element. This is not nessesary for elements which natively support input, such as a Button.
This example creates a tap gesture recognizer and associates it with an image. When the image is double tapped, it will become semi-transparent.
var image = new Image {Source = "image.png"};
var gestureRecognizer = new TapGestureRecognizer {
TappedCallback = o => image.Opacity = 0.5,
NumberOfTapsRequired = 2
};
image.GestureRecognizers.Add (gestureRecognizer);
