UIElement.MouseWheel Event

 

Occurs when the user rotates the mouse wheel while the mouse pointer is over this element.

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public event MouseWheelEventHandler MouseWheel

Focus or mouse capture take precedence over where the mouse pointer is; therefore, if you receive the MouseWheel event from a focused or captured element, the mouse pointer might actually be over another element.

This event creates an alias for the Mouse.MouseWheel attached event for this class, so that MouseWheel is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the MouseWheel event are attached to the underlying Mouse.MouseWheel attached event and receive the same event data instance.
