ContentElement.PreviewMouseWheel 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 PreviewMouseWheel

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

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