The MouseWheelEventArgs type exposes the following members.

Properties

Name Description
Delta Gets a value that indicates the amount that the mouse wheel rotated relative to its starting state or to the last occurrence of the event.
Handled Gets or sets a value that marks the routed event as handled, and prevents most handlers along the event route from rehandling the same event.
OriginalSource Gets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)
StylusDevice Gets an object that reports stylus device information, such as the collection of stylus points associated with the input. (Inherited from MouseEventArgs.)

Methods

Name Description
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetPosition Returns the x- and y-coordinates of the pointer position, optionally evaluated against a coordinate origin of a supplied UIElement. (Inherited from MouseEventArgs.)
GetType Gets the Type of the current instance. (Inherited from Object.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

Because MouseWheel is a routed event, it can invoke handlers on objects other than the object that raised the event. MouseWheelEventArgs has a Handled property, which enables marking the event as handled and shortens the event route in all but exceptional handling cases.
